Radiative corrections to the Z0 resonance.
We review calculations of the radiative corrections to the Z” resonance, and we show that while the radiative corrections are quite large, they can be calculated and incorporated into the comparison with experiment so that there will be no significant theoretical uncertainties on the measurements of the 2’ mass and width at SLC and LEP. We compare calculations based on matrix elements and struc...
متن کاملQED ⊗ QCD Threshold Corrections at the LHC †
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 controlle...
متن کاملThreshold 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 Corrections to Associated tt̄h Production at the Tevatron
We present in detail the calculation of the O(α 3 s) inclusive total cross section for the process pp → tth in the Standard Model, at the Tevatron center-of-mass energy √ s H = 2 TeV. The next-to-leading order QCD corrections significantly reduce the renormalization and factorization scale dependence of the Born cross section. They slightly decrease or increase the Born cross section depending ...
متن کاملBose-einstein Correlations at the Z0 Peak
Presented here is an overview of studies of the manifestations of the Bose-Einstein correlations in the hadronic decays of Z 0 boson, performed by the LEP experiments. The scope of the overview is connned to studies of two-and three-particle correlation functions for charged pions, with emphasis on analyses of transverse mass m T and directional dependence of the two-particle correlation functi...
