Top quark threshold production in γγ collisions : current theoretical issues ⋆
The top quark-antiquark pair threshold production at future High Energy Photon Colliders is considered in view of the recent advances in the theoretical description of the nonrelativistic heavy quark dynamics.
متن کاملHeavy quark production in γγ collisions: a theoretical reappraisal
Heavy quark production in γγ collisions is analyzed within the approach to hard collisions of photons recently proposed by the author. In this approach evaluating the cross section σ(γγ → QQ) in the “next–to–leading order of QCD” requires the inclusion of direct photon contributions up to the order αα s, whereas in the standard approach direct photon terms only up to the order ααs are taken int...
متن کاملHeavy quark production in γγ collisions revisited
Heavy quark production in γγ collisions is reanalyzed. It is argued that evaluating the cross section σ(γγ → QQ) in a well-defined renormalization scheme requires the inclusion of direct photon contributions up to the order α 2 α 2 s. The order α 2 α 2 s direct photon contributions are furthermore needed for factorization scale invariance of the sum of direct and resolved photon contributions. ...
متن کاملHeavy Quark Production in Γγ Collisions
Heavy quark production in γγ collisions has recently received increased theoretical attention 1,2,3 motivated in part by new experimental data on cc and bb production from LEP2 (see 4 for references). Although the data on bb production have sizable errors and the theoretical predictions suffer from uncertainties, the excess by a factor of about three of the data over theoretical predictions rep...
متن کاملTop quark production near threshold ∗
Only a few of the top quark’s properties are currently known. In the future the Tevatron and the LHC, and a Linear Collider, will measure many of its couplings in great detail. This will tell us whether the top quark is just another standard model quark (in which case it would be a rather uninteresting one) or whether it plays a special role in physics beyond the standard model, as perhaps its ...
