Top quark pair production near the threshold in e+e- collisions
Takaaki Nagano
It was reported that the NNLO correction to the total cross section near the ttbar threshold in e+e- collisions is as large as the NLO correction to it. In the thesis, we improve t…

A. H. Hoang, M. Beneke, K. Melnikov +10
Using non-relativistic effective theories, new next-to-next-to-leading order (NNLO) QCD corrections to the total production cross section at the Linear Collider have been…
