Next-to-next-to-leading order soft-gluon corrections in top quark hadroproduction
We calculate next-to-next-to-leading order soft-gluon corrections to top quark total and differential cross sections in hadron colliders. We increase the accuracy of our previous estimates by including additional subleading terms, including next-to-next-to-next-toleading-logarithmic and some virtual terms. We show that the kinematics dependence of the cross section vanishes near threshold and i...
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 کاملTop 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 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 Quark Pair + Jet Production at Next-to-leading Order: Nlo Qcd Corrections to Gg → T ¯ Tg Top Quark Pair + Jet Production at Next-to-leading Order: Nlo Qcd Corrections to Gg → T ¯ Tg
The reaction pp/p ¯ p → t ¯ t +jet+X is an important background process for Higgs boson searches in the mass range below 200 GeV. Apart from that it is also an ideal laboratory for precision measurements in the top quark sector. Both applications require a solid theoretical prediction, which can be achieved only through a full next-to-leading order (NLO) calculation. In this work we describe th...
