Next-to-Next-to-Leading Order Event Generation for Top-Quark Pair Production
نویسندگان
چکیده
The production of top-quark pairs in hadronic collisions is among the most important reactions modern particle physics phenomenology and constitutes an instrumental avenue to study properties heaviest quark observed nature. analysis this process at Large Hadron Collider relies heavily on Monte Carlo simulations final state events, whose accuracy challenged by outstanding precision experimental measurements. In Letter we present first matched computation pair next-to-next-to-leading order QCD with all-order radiative corrections as implemented via parton-shower simulations. Besides its intrinsic relevance for LHC phenomenology, work also establishes step towards simulation other processes color charges state.

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.

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...
متن کاملNext-to-Next-to-Leading Logarithm Resummation for S-Channel Single Top Quark Production
I present the next-to-next-to-leading-logarithm (NNLL) resummation of soft and collinear gluon corrections to single top quark production in the s channel. Attaining NNLL accuracy involves the calculation of the two-loop soft anomalous dimension for the partonic subprocesses. Finite-order expansions of the resummed cross section are calculated through next-to-next-to-leading order (NNLO). Numer...
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....
