The electroweak corrections at one-loop level to the process $H\rightarrow t{\bar t}$ are calculated, especially the fresh top mass value announced recently by CDF is concerned. For $M_H < 1. TeV$ where a perturbative calculation is valid,…
The large double logarithm in loop-induced processes is one kind of logarithm at subleading power, which has a different origin from Sudakov double logarithms. We develop a method with soft-collinear effective theory to resum these large…
