 P: 57 Hi all, I'd like to more understand what is the difference between when we draw the differential cross section ## \frac{d \sigma ~ (pb)}{dM ~ (GeV)} ##, when we draw ## \sigma ~ (pb) /bin## and the total cross section ## \sigma ~ (pb) ## .. I mean for a process like p p > x x~ (where x is a particle has mx=100 GeV) .. ## \frac{d \sigma ~ (pb)}{dM ~ (GeV)} ## and ## \sigma ~ (pb) /bin ## VS. mx gives a peak at 100 GeV while ## \sigma ~ (pb) ## gives the variation of ## \sigma ## with mx .. Bests, Safinaz
