branching ratio

Asked by said ghourmin

Hi
i would like to calculate the cross section of the prosses p p > h+ h++ , h++ > w+ w+ using MG but i have found magic value i don't know is that problem of exist additional diagram. as we know the we can calculate the xsect of this process by sigma(pp > h+ h++).BR(h++ > w+ w+). my question if i calculate sigma(pp > h+ h++) alone and also i calculate BR(h++ > w+ w+ ) from decay h++ > XY and i did the product is that correct? all of that using MG.
