Search for heavy neutrinos or third-generation leptoquarks in final states with two hadronically decaying τ leptons and two jets in proton-proton collisions at \( \sqrt{s}=13 \) TeV

A search for new particles has been conducted using events with two high transverse momentum (p T) τ leptons that decay hadronically, at least two high-p T jets, and missing transverse energy from the τ lepton decays. The analysis is performed using data from proton-proton collisions, collected by the CMS experiment in 2015 at \( \sqrt{s}=13 \) TeV, corresponding to an integrated...

Measurement of the transverse momentum spectrum of the Higgs boson produced in pp collisions at \( \sqrt{s}=8 \) TeV using H → WW decays

The cross section for Higgs boson production in pp collisions is studied using the H → W+W− decay mode, followed by leptonic decays of the W bosons to an oppositely charged electron-muon pair in the final state. The measurements are performed using data collected by the CMS experiment at the LHC at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19...

Search for dark matter particles in proton-proton collisions at \( \sqrt{s}=8 \) TeV using the razor variables

A search for dark matter particles directly produced in proton-proton collisions recorded by the CMS experiment at the LHC is presented. The data correspond to an integrated luminosity of 18.8 fb−1, at a center-of-mass energy of 8 TeV. The event selection requires at least two jets and no isolated leptons. The razor variables are used to quantify the transverse momentum balance...

Measurement of electroweak production of a W boson and two forward jets in proton-proton collisions at \( \sqrt{s}=8 \) TeV

A measurement is presented of the cross section for the electroweak production of a W boson in association with two jets in proton-proton collisions at a center-of-mass energy of 8 TeV. The data set was collected with the CMS detector and corresponds to an integrated luminosity of 19.3 fb−1. The measured fiducial cross section for W bosons decaying to electrons or muons and for p...

Decomposing transverse momentum balance contributions for quenched jets in PbPb collisions at \( \sqrt{s_{\mathrm{N}\;\mathrm{N}}}=2.76 \) TeV

Interactions between jets and the quark-gluon plasma produced in heavy ion collisions are studied via the angular distributions of summed charged-particle transverse momenta (p T) with respect to both the leading and subleading jet axes in high-p T dijet events. The contributions of charged particles in different momentum ranges to the overall event p T balance are decomposed...

Search for s channel single top quark production in pp collisions at \( \sqrt{s}=7 \) and 8 TeV

A search is presented for single top quark production in the s channel in proton-proton collisions with the CMS detector at the CERN LHC in decay modes of the top quark containing a muon or an electron in the final state. The signal is extracted through a maximum-likelihood fit to the distribution of a multivariate discriminant defined using boosted decision trees to separate the...

Measurement of the \( \mathrm{t}\overline{\mathrm{t}} \) production cross section in the eμ channel in proton-proton collisions at \( \sqrt{s}=7 \) and 8 TeV

The inclusive cross section for top quark pair production is measured in proton-proton collisions at \( \sqrt{s}=7 \) and 8 TeV, corresponding to 5.0 and 19.7 fb−1, respectively, with the CMS experiment at the LHC.
