Special features of heavy quark - antiquark pair production ratios at LHC ∗

چکیده
We consider the ratio of the cross section of production of heavy bottom-antibottom pairs (σ b ¯ b) to the cross section of production of top-antitop pairs (σ t ¯ t) at LHC. We show that in this ratio a major fraction of virtual contributions (including QCD components) disappears, leaving a residual dominant electroweak Yukawa effect that might be strongly enhanced in the presence of supersymmetry. A quantitative numerical analysis of the size of the effect is also performed under the assumption of a relatively light supersymmetric scenario.

Two-loop fermionic corrections to heavy-quark pair production: the quark-antiquark channel
We evaluate the fermionic two-loop QCD corrections to the heavy-quark pair production process in the quark-antiquark channel. We obtain analytic results which are valid for any value of the Mandelstam invariants s and t, and of the heavy quark mass m. Our findings confirm previous results for the analytic evaluation in the small-mass limit and numerical results for the exact amplitude. We furth...
متن کاملElectroweak corrections to top-quark pair production in quark–antiquark annihilation
Top-quark physics plays an important rôle at hadron colliders such as the Tevatron at Fermilab or the LHC at CERN. Given the planned precision at these colliders, precise theoretical predictions are required. In this paper we present the complete electroweak corrections to QCD-induced top-quark pair production in quark–antiquark annihilation. In particular we provide compact analytic expression...
متن کاملGauge-Boson Pair Production at the LHC: Anomalous Couplings and Vector-Boson Scattering
We compare vector boson fusion and quark antiquark annihilation production of vector boson pairs at the LHC and include the effects of anomalous couplings. Results are given for confidence intervals for anomalous couplings at the LHC assuming that measurements will be in agreement with the standard model. We consider all couplings of the general triple vector boson vertex and their correlations...
متن کاملA heavy quark effective field lagrangian keeping particle and antiparticle mixed sectors
We derive a tree-level heavy quark effective Lagrangian keeping particle-antiparticle mixed sectors allowing for heavy quark-antiquark pair annihilation and creation. However, when removing the unwanted degrees of freedom from the effective Lagrangian one has to be careful in using the classical equations of motion obeyed by the effective fields in order to get a convergent expansion on the rec...
متن کاملSupersymmetric virtual effects in heavy quark pair production at LHC ∗
We consider the production of heavy (b, t) quark pairs at proton colliders in the theoretical framework of the MSSM. Under the assumption of a " moderately " light SUSY scenario, we first compute the leading logarithmic MSSM contributions at one loop for the elementary processes of production from a quark and from a gluon pair in the 1 TeV c.m. energy region. We show that in the initial gluon p...
