QED ⊗ QCD Threshold Corrections at the LHC †

چکیده
We use the theory of YFS resummation to compute the size of the expected resummed soft radiative threshold effects in precision studies of heavy particle production at the LHC, where accuracies of 1% are desired in some processes. We find that the soft QED threshold effects are at the level of 0.3% whereas the soft QCD threshold effects enter at the level of 20% and hence both must be controlled to be on the conservative side to achieve such goals.

Threshold Corrections in Qed ⊗ Qcd at the Lhc
In some processes at the LHC, theoretical precisions of 1% are desired. With an eye toward such precisions, we introduce the theory of the simultaneous YFS resummation of QED and QCD to compute the size of the expected resummed soft radiative threshold effects in precision studies of heavy particle production at the LHC. Our results, that the soft QED threshold effects are at the level of 0.3% ...
متن کاملQCD and QED Corrections to Higgs Boson Production in Charged Current ep Scattering
First order QCD and leading QED corrections to Higgs boson production in the channel ep → νHX ;H → bb̄ are calculated for the kinematical conditions at LEP ⊗ LHC (√s = 1360GeV) and the interesting mass range 80 < MH < 150GeV. In the DIS scheme the QCD corrections (not including the corrections to the branching ratio, which are well-known) are found to be about 1% for the total cross section and ...
متن کاملPrecision QED⊗QCD Resummation Theory for LHC Physics: IR-Improved Scheme for Parton Distributions, Kernels, Reduced Cross Sections with Shower/ME Matching
We summarize the recent progress in a new approach to precision LHC physics based on the IR-improved DGLAP-CS theory as it relates to a new MC friendly exponentiated scheme for precision calculation of higher order corrections to LHC physics in which IR singularities from both QED and QCD are canceled to all orders in α and in αs simultaneously in the presence of rigorous shower/ME matching. We...
متن کاملThreshold Effects in Slepton Pair Production at the LHC
We present a study of threshold resummation effects for slepton pair production at the Large Hadron Collider (LHC). After confirming the known NLO QCD corrections and generalizing the NLO SUSY-QCD corrections to the case of mixing squarks in the virtual loop contributions, we employ the Mellin N -space resummation formalism to compute logarithmically enhanced soft-gluon terms to all perturbativ...

Deep inelastic electron–nucleon scattering allows for fundamental QCD tests investigating the scaling violations of structure functions in the perturbative regime of large values of Q. The detailed knowledge of the structure functions enables to study various aspects of the dynamics of nonAbelian gauge theory, and is necessary for the future experimental search for the Higgs–boson and new parti...
