Top Quark Pair Production at Threshold: Complete Next-to-next-to-leading Order Relativistic Corrections
The complete next-to-next-to-leading order (i.e. O(v2), O(vαs) and O(αs)) relativistic corrections to the total photon mediated tt̄ production cross section at threshold are presented in the framework of nonrelativistic quantum chromodynamics. The results are obtained using semi-analytic methods and “direct matching”. The size of the next-to-next-to-leading order relativistic corrections is foun...
متن کاملHiggs boson pair production at the LHC: top-quark mass effects at next-to-leading order
Higgs boson pair production is considered at next-to-leading order with special emphasis on the effect of a finite top quark mass. It is shown that, unlike for single-Higgs boson production, power-suppressed corrections are numerically important.
متن کاملTop-quark decay at next-to-next-to-leading order in QCD.
We present the complete calculation of the top-quark decay width at next-to-next-to-leading order in QCD, including next-to-leading electroweak corrections as well as finite bottom quark mass and W boson width effects. In particular, we also show the first results of the fully differential decay rates for the top-quark semileptonic decay t → W(+)(l(+)ν)b at next-to-next-to-leading order in QCD....
متن کاملThreshold corrections in bottom and charm quark hadroproduction at next-to-next-to-leading order
We calculate threshold soft-gluon corrections to total cross sections and transverse momentum distributions for bottom and charm quark production in fixed-target experiments, considering both pp and π−p interactions. We investigate the quality of the near threshold soft-gluon approximation at next-to-leading order (NLO) and calculate next-to-nextto-leading order (NNLO) corrections through next-...
متن کاملTop mass effects in Higgs production at next-to-next-to-leading order QCD: virtual corrections
Top quark mass suppressed terms are calculated for the virtual amplitude for Higgs production in gluon fusion at three-loop level, i.e. O(α3 s ). The method of asymptotic expansions in its automated form is used to evaluate the first three non-vanishing orders in terms of M H /M t , where the first order corresponds to the known results of the effective Lagrangian approach.
