Electroweak corrections to Wγ and Zγ production at the LHC
We have calculated the electroweak O(α) corrections to the processes pp → Zγ+X → νlν̄lγ +X, pp → Zγ +X → ll̄γ +X, and pp → Wγ +X → νl l̄γ +X at the LHC, with l = e, μ and νl = νe, νμ, ντ . The virtual corrections are evaluated in leading-pole approximation, whereas the real corrections are taken into account exactly. These corrections are implemented into a Monte Carlo generator which includes bot...
متن کاملElectroweak Corrections to t-channel single top production at the LHC
— We describe the computation of the O(α) corrections for single top (and single anti-top) production in the t-channel at hadron colliders. We show also The genuine one loop SUSY contribution to these processes. Such contributions are generally quite modest in the mSUGRA scenario. The experimental observables would therefore only practically depend, in this framework, on the CKM Wtb coupling.
متن کاملExclusive Higgs boson production at the LHC: hard rescattering corrections
We examine, as a correction to the central exclusive Higgs boson production in pp collisions at the LHC, the rescattering of gluonic ladders off the proton. As usual, at the lowest order the hard part of this process can be described as a fusion of two hard gluonic ladders. We calculate corrections to this hard amplitude which are due to rescattering of these ladders. These corrections, which c...
متن کاملSupersymmetric Electroweak Corrections to Top Quark Production at LHC
The αmt /m 2 W order supersymmetric electroweak corrections arising from loops of chargino, neutralino, and squark to top quark pair production by gg fusion at LHC are calculated in the minimal supersymmetric model. We found that the corrections amount about a few percent.
متن کاملNNLL Electroweak Corrections to Gauge Boson Pair Production at LHC
The high energy behaviour of electroweak corrections to gauge boson pair production at LHC can be derived in the framework of evolution equations up to NNLL contributions to all order in perturbation theory. On the basis of this general result we derive the one-and two-loop cross section in NNLL approximation for W-pair production at partonic and hadronic level. c Copyright owned by the author(...
