محاسبه فرم فاکتور برای واپاشی کوارک top

چکیده مقاله

In this paper, we have calculated the form factors that required in calculation the decay amplitudes and the branching ratios of the top quark dominant decays i.e. t b m → + and the rare decays of this quark, like 0 0 / / ( / ) s t B B u c →  + decays. To calculate these form factors, we used the BWS method and by using these form factors, the calculated branching ratios are in very good agreement with the references data. .تسا هدش هدافتسا
