Selected Topics in Top Quark Physics | | J.G. Körner
; | | Date: |
5 Sep 2006 | | Abstract: | I discuss three different selected topics in top quark physics. The first topic concerns the next-to-next-to-leading order calculation of the hadroproduction of top quark pairs and the role of multiple polylogarithms in this calculation. I report on an ongoing next-to-next-to-leading order calculation of heavy quark pair production in hadron collisions where the loop--by--loop part of the calculation is about to be completed. Calculating the loop-by-loop part allows one to take a glimpse at the mathematical structure of the full NNLO calculation. The loop-by-loop contributions bring in a new class of functions introduced only eight years ago by the Russian mathematician Goncharov called multiple polylogarithms. The second topic concerns a next-to-leading order calculation of unpolarized top quark decays which are analyzed in cascade fashion $t o b + W^+$ followed by $W^+ o l^+ +
u_l$. Finally, I present some next-to-leading order results on polarized top quark decays which are analyzed in the top quark rest system. | | Source: | arXiv, hep-ph/0609048 | | Services: | Forum | Review | PDF | Favorites | |
