Abstract

We study electroweak Sudakov corrections in high energy scattering, and the cancellation between real and virtual Sudakov corrections. Numerical results are given for the case of heavy quark production by gluon collisions involving the rates gg→t¯t, b¯b, t¯bW, t¯tZ, b¯bZ, t¯tH, b¯bH. Gauge boson virtual corrections are related to real transverse gauge boson emission, and Higgs virtual corrections to Higgs and longitudinal gauge boson emission. At the LHC, electroweak corrections become important in the TeV regime. At the proposed 100TeV collider, electroweak interactions enter a new regime, where the corrections are very large and need to be resummed.

Electroweak logarithms in inclusive cross sections

Journal Article Manohar, Aneesh V. ; Waalewijn, Wouter J. - Journal of High Energy Physics (Online)

We expand the framework to perform all-orders resummation of electroweak logarithms of Q/M for inclusive scattering processes at energies Q much above the electroweak scale M. We determine all ingredients needed at next-to-leading logarithmic (NLL) order and provide an explicit recipe to implement this for 2 → 2 processes. PDF evolution including electroweak corrections, which lead to Sudakov double logarithms, is computed. If only the invariant mass of the final state is measured, all electroweak logarithms can be resummed by the PDF evolution, at least to LL. However, simply identifying a lepton in the final state requires the corresponding fragmentationmore »« less

Resummation of Yukawa enhanced and subleading Sudakov logarithms in longitudinal gauge boson and Higgs boson production

Journal Article Melles, Michael - Physical Review D

Future colliders will probe the electroweak theory at energies much larger than the gauge boson masses. Large double (DL) and single (SL) logarithmic virtual electroweak Sudakov corrections lead to significant effects for observable cross sections. Recently, leading and subleading universal corrections for external fermions and transverse gauge boson lines were resummed by employing the infrared evolution equation method. The results were confirmed at the DL level by explicit two loop calculations with the physical standard model (SM) fields. Also for longitudinal degrees of freedom the approach was utilized for DL corrections via the Goldstone boson equivalence theorem. In all cases,more »« less

Electroweak splitting functions and high energy showering

Journal Article Chen, Junmou ; Han, Tao ; Tweedie, Brock - Journal of High Energy Physics (Online)

We derive the electroweak (EW) collinear splitting functions for the Standard Model, including the massive fermions, gauge bosons and the Higgs boson. We first present the splitting functions in the limit of unbroken SU(2)_L × U(1)_Y and discuss their general features in the collinear and soft-collinear regimes. These are the leading contributions at a splitting scale (k_T) far above the EW scale (v). We then systematically incorporate EW symmetry breaking (EWSB), which leads to the emergence of additional “ultra-collinear” splitting phenomena and naive violations of the Goldstone-boson Equivalence Theorem. We suggest a particularly convenient choice of non-covariant gauge (dubbed “Goldstonemore »« less

Factorization structure of gauge theory amplitudes and application to hard scattering processes at the LHC

Journal Article Juiyu, Chiu ; Fuhrer, Andreas ; Kelley, Randall ; ... - Physical Review. D, Particles Fields

Previous work on electroweak radiative corrections to high-energy scattering using soft-collinear effective theory (SCET) has been extended to include external transverse and longitudinal gauge bosons and Higgs bosons. This allows one to compute radiative corrections to all parton-level hard scattering amplitudes in the standard model to next-to-leading-log order, including QCD and electroweak radiative corrections, mass effects, and Higgs exchange corrections, if the high-scale matching, which is suppressed by two orders in the log counting, and contains no large logs, is known. The factorization structure of the effective theory places strong constraints on the form of gauge theory amplitudes at highmore »« less
