A fast and accurate method for perturbative resummation of transverse momentum-dependent observables

AbstractWe propose a novel strategy for the perturbative resummation of transverse momentum-dependent (TMD) observables, using the q T spectra of gauge bosons (γ∗, Higgs) in pp collisions in the regime of low (but perturbative) transverse momentum q T as a specific example. First we introduce a scheme to choose the factorization scale for virtuality in momentum space instead of...

Semi-inclusive wino and higgsino annihilation to LL′

We systematically compute the annihilation rate for winos and higgsinos into the final state relevant for indirect detection experiments, γ + X. The radiative corrections to this process receive enhancement from the large Bloch-Nordsieck-Violating Sudakov logarithm, log(2M χ /M W ). We resum the double logs and include single logs to fixed order using a formalism that combines...

Comparison of charges and resource use associated with saxagliptin and sitagliptin

Objectives Saxagliptin and sitagliptin are two commonly used dipeptidyl peptidase-4 (DPP-4) inhibitors. Little is known about their comparative effectiveness in the real world, particularly their impact on cost and resources use. The objective of this study was to analyze charges and resource use associated with saxagliptin and sitagliptin to understand the impact of these DPP-4...

The Higgs transverse momentum distribution at NNLL and its theoretical errors

In this letter, we present the NNLL-NNLO transverse momentum Higgs distribution arising from gluon fusion. In the regime p ⊥ ≪ m h we include the resummation of the large logs at next to next-to leading order and then match on to the α s 2 fixed order result near p ⊥ ∼ m h . By utilizing the rapidity renormalization group (RRG) we are able to smoothly match between the resummed...

Constraints on galactic wino densities from gamma ray lines

We systematically compute the annihilation rate for neutral winos into the final state γ + X, including all leading radiative corrections. This includes both the Sommerfeld enhancement (in the decoupling limit for the Higgsino) and the resummation of the leading electroweak double logarithms. Adopting an analysis of the HESS experiment, we place constraints on the mass as a...
