Antenna Shower and its NLO corrections

by 海涛 李


Abstract: Monte-Carlo event generators have been widely used in high energy physics by experimentalists and theorists. Parton Shower is the key component of them. In this talk I will discuss the NLO QCD corrections to antenna shower. The formalism allows to combine NLO corrected as iterated 2 → 3 kernels for “ordered” gluon emissions with tree-level 2 → 4 kernels for “unordered” ones.  Within this framework, we proposed  a new technique for the fully-differential matching of final-state parton showers to NNLO calculations, focussing here on the simplest case of leptonic collisions with two final-state jets.
