Main Question or Discussion Point

Hi there :)

I'm currently looking at Higgs Branching ratios. The fermions are all behaving as expected from the Yukawa terms and producing results proportional to mass. I'm a bit confused however that my WW (and WW*) BRs are higher than ZZ (and ZZ*), I was expecting tem to be the other way around - what is causing this result? On a simular note, I am also finding higher cross sections for W's than Zs for Higgs production via both Bremstrahlung and WW, ZZ fusion.

Thank you very much in advance

oops - I have just read the 'homework and coursework rules', just to be clear this is a dissertation related question. I have asked my supervisor and he is not sure exactly why this is happening but is happy for me to talk to someone else - I would definately explain that I asked on a forum. I hope this addresses any potential cheating at homework problems - I can repost in the homework section if need be.

thanks again is advance

There are two W's and only one Z. So there are two ways to make WW* (W+W*- and vice versa) but only one to make ZZ.
