#### A 6D nonabelian (1, 0) theory

Abstract We construct a 6D nonabelian $\mathcal{N}=\left(1,\ 0\right)$ theory by coupling an $\mathcal{N}=\left(1,\ 0\right)$ tensor multiplet to an $\mathcal{N}=\left(1,\ 0\right)$ hypermultiplet. While the $\mathcal{N}=\left(1,\ 0\right)$ tensor multiplet is in the adjoint representation of the gauge group, the hypermultiplet can be in the fundamental...

#### Charting generalized supersoft supersymmetry

Abstract Without any shred of evidence for new physics from LHC, the last hiding spots of natural electroweak supersymmetry seem to lie either in compressed spectra or in spectra where scalars are suppressed with respect to the gauginos. While in the MSSM (or in any theory where supersymmetry is broken by the F-vev of a chiral spurion), a hierarchy between scalar and gaugino...

#### LeClair-Mussardo series for two-point functions in Integrable QFT

Abstract We develop a well-defined spectral representation for two-point functions in relativistic Integrable QFT in finite density situations, valid for space-like separations. The resulting integral series is based on the infinite volume, zero density form factors of the theory, and certain statistical functions related to the distribution of Bethe roots in the finite density...

#### Status of the semileptonic B decays and muon g-2 in general 2HDMs with right-handed neutrinos

Abstract In this paper, we study the extended Standard Model (SM) with an extra Higgs doublet and right-handed neutrinos. If the symmetry to distinguish the two Higgs doublets is not assigned, flavor changing neutral currents (FCNCs) involving the scalars are predicted even at the tree level. We investigate the constraints on the FCNCs at the one-loop level, and especially study...

#### Some remarks on anthropic approaches to the strong CP problem

Abstract The peculiar value of θ is a challenge to the notion of an anthropic landscape. We briefly review the possibility that a suitable axion might arise from an anthropic requirement of dark matter. We then consider an alternative suggestion of Kaloper and Terning that θ might be correlated with the cosmological constant. We note that in a landscape one expects that θ is...

#### The $T\overline{T}$ deformation at large central charge

Abstract We study Zamolodchikov’s $T\overline{T}$ deformation of two dimensional quantum field theories in a ’t Hooft-like limit, in which we scale the number of degrees of freedom c to infinity and the deformation parameter t to zero, keeping their product t · c fixed (more precisely, we keep energies and distances fixed in units of t · c). In this limit the Hagedorn...

#### SU(2|1) supersymmetric mechanics on curved spaces

Abstract We present SU(2|1) supersymmetric mechanics on n-dimensional Riemannian manifolds within the Hamiltonian approach. The structure functions including prepotentials entering the supercharges and the Hamiltonian obey extended curved WDVV equations specified by the manifold’s metric and curvature tensor. We consider the most general u(2)-valued prepotential, which contains...

#### Update of global Two-Higgs-Doublet model fits

Abstract We perform global fits of Two-Higgs-Doublet models with a softly broken ℤ2 symmetry to recent results from the LHC detectors CMS and ATLAS, that is signal strengths and direct search limits obtained at $\sqrt{s}=8$ TeV and $\sqrt{s}=13$ TeV. We combine all available ATLAS and CMS constraints with the other relevant theoretical and experimental bounds and present...

#### Search for a heavy right-handed W boson and a heavy neutrino in events with two same-flavor leptons and two jets at $\sqrt{s}=13$ TeV

Abstract A search for a heavy right-handed W boson (WR) decaying to a heavy right-handed neutrino and a charged lepton in events with two same-flavor leptons (e or μ) and two jets, is presented. The analysis is based on proton-proton collision data, collected by the CMS Collaboration at the LHC in 2016 and corresponding to an integrated luminosity of 35.9 fb−1. No significant...

#### A new insight into the phase transition in the early Universe with two Higgs doublets

Abstract We study the electroweak phase transition in the alignment limit of the CP-conserving two-Higgs-doublet model (2HDM) of Type I and Type II. The effective potential is evaluated at one-loop, where the thermal potential includes Daisy corrections and is reliably approximated by means of a sum of Bessel functions. Both 1-stage and 2-stage electroweak phase transitions are...

#### Addendum to: Scheming in the SMEFT. . . and a reparameterization invariance!

Abstract We allow two independent flavor contractions for the operator ${\mathcal{Q}}_{ll}$ in the U(3)5 flavor symmetric limit and report modified fit results in this limit.

#### Scale-invariant scalar field dark matter through the Higgs portal

Abstract We discuss the dynamics and phenomenology of an oscillating scalar field coupled to the Higgs boson that accounts for the dark matter in the Universe. The model assumes an underlying scale invariance such that the scalar field only acquires mass after the electroweak phase transition, behaving as dark radiation before the latter takes place. While for a positive coupling...

#### N = 1 supercurrents of eleven-dimensional supergravity

Abstract Eleven-dimensional supergravity can be formulated in superspaces locally of the form X × Y where X is 4D N = 1 conformal superspace and Y is an arbitrary 7-manifold admitting a G2-structure. The eleven-dimensional 3-form and the stable 3-form on Y define the lowest component of a gauge superfield on X × Y that is chiral as a superfield on X. This chiral field is part of...

#### Leptoquark toolbox for precision collider studies

Abstract We implement scalar and vector leptoquark (LQ) models in the universal FeynRules output (UFO) format assuming the Standard Model fermion content and conservation of baryon and lepton numbers. Scalar LQ implementations include next-to-leading order (NLO) QCD corrections. We report the NLO QCD inclusive cross sections in proton-proton collisions at 13 TeV, 14 TeV, and 27...

#### A note on the entropy of rotating BPS AdS7 × S4 black holes

Abstract In this note we show that the entropy of BPS, rotating, electrically charged AdS7 × S4 black holes can be obtained by an extremization principle involving a particular combination of anomaly coefficients of the six-dimensional $\mathcal{N}=\left(2,0\right)$ theory. This result extends our previous finding for BPS, rotating AdS5 × S5 black holes.

#### Partition functions on 3d circle bundles and their gravity duals

Abstract The partition function of a three-dimensional $\mathcal{N}=2$ theory on the manifold ℳg,p, an S1 bundle of degree p over a closed Riemann surface Σ g , was recently computed via supersymmetric localization. In this paper, we compute these partition functions at large N in a class of quiver gauge theories with holographic M-theory duals. We provide the supergravity...

#### Electroweak gauge boson parton distribution functions

Abstract Transverse and longitudinal electroweak gauge boson parton distribution functions (PDFs) are computed in terms of deep-inelastic scattering structure functions, following the recently developed method to determine the photon PDF. The calculation provides initial conditions at the electroweak scale for PDF evolution to higher energies. Numerical results for the W ± and Z...

#### Ghostbusters in f (R) supergravity

Abstract f (R) supergravity is known to contain a ghost mode associated with higher-derivative terms if it contains R n with n greater than two. We remove the ghost in f (R) supergravity by introducing auxiliary gauge field to absorb the ghost. We dub this method as the ghostbuster mechanism [1]. We show that the mechanism removes the ghost super-multiplet but also terms...

#### Exact correlators on the Wilson loop in $\mathcal{N}=4$ SYM: localization, defect CFT, and integrability

AbstractWe compute a set of correlation functions of operator insertions on the 1/8 BPS Wilson loop in $\mathcal{N}=4$ SYM by employing supersymmetric localization, OPE and the Gram-Schmidt orthogonalization. These correlators exhibit a simple determinant structure, are position-independent and form a topological subsector, but depend nontrivially on the ’t Hooft coupling and...

#### The singularity structure of scale-invariant rank-2 Coulomb branches

Abstract We compute the spectrum of scaling dimensions of Coulomb branch operators in 4d rank-2 $\mathcal{N}=2$ superconformal field theories. Only a finite rational set of scaling dimensions is allowed. It is determined by using information about the global topology of the locus of metric singularities on the Coulomb branch, the special Kähler geometry near those...

#### Measurement of differential cross sections and W+/W− cross-section ratios for W boson production in association with jets at $\sqrt{s}=8$ TeV with the ATLAS detector

Abstract This paper presents a measurement of the W boson production cross section and the W +/W − cross-section ratio, both in association with jets, in proton-proton collisions at $\sqrt{s}=8$ TeV with the ATLAS experiment at the Large Hadron Collider. The measurement is performed in final states containing one electron and missing transverse momentum using data...

#### Towards an explicit model of large field inflation

Abstract The unwinding inflation mechanism is studied in a type IIB flux compactification where all moduli are stabilized using flux, non-perturbative effects, and the leading α′ corrections of the large volume scenario. We consider the backreaction on the geometry due to the presence of anti-D3 branes as well as the backreaction of inflation on the Kähler moduli, and compute the...

#### Casimir squared correction to the standard rotator Hamiltonian for the O(n) sigma-model in the delta-regime

Abstract In a previous paper we found that the isospin susceptibility of the O(n) sigma-model calculated in the standard rotator approximation differs from the next-to-next-to leading order chiral perturbation theory result in terms vanishing like 1/ℓ, for ℓ = L t /L → ∞ and further showed that this deviation could be described by a correction to the rotator spectrum proportional...

#### Higher-order Skyrme hair of black holes

Abstract Higher-order derivative terms are considered as replacement for the Skyrme term in an Einstein-Skyrme-like model in order to pinpoint which properties are necessary for a black hole to possess stable static scalar hair. We find two new models able to support stable black hole hair in the limit of the Skyrme term being turned off. They contain 8 and 12 derivatives...

#### Probing neutrino coupling to a light scalar with coherent neutrino scattering

Abstract Large neutrino event numbers in future experiments measuring coherent elastic neutrino nucleus scattering allow precision measurements of standard and new physics. We analyze the current and prospective limits of a light scalar particle coupling to neutrinos and quarks, using COHERENT and CONUS as examples. Both lepton number conserving and violating interactions are...
