Implementing invariant mass cuts and finite lifetime effects in top-antitop production at threshold
arXiv:0810.2934 · doi:10.1016/j.nuclphysbps.2008.12.091
Abstract
The effects of the finite top quark width in the top pair production cross section close to the threshold are discussed in this talk. We introduce a cross section with a cut on the invariant masses of the top and antitop that can be calculated theoretically with effective field theory (EFT) methods. The matching procedure to implement the physical phase-space boundaries in the NRQCD framework (``phase-space matching'') is briefly outlined.
