Di-Higgs decays to bb~ aa
Asked by
Harshal Kulkarni
Hi,
I want to generate the process p p > h h at the tree level and then decay the h h pair to h h > b b~ a a using MG5. (I have included the b and b~ quarks in the definition of p). I tried using the syntax p p > h h > b b~ a a, but this only generates the processes with at least one intermediate h in the s-channel, whereas I want to produce both the Higgs and then decay them further. How exactly do I do this?
Also, if I want to generate the process p p > b b~ a a with no intermediate h h pair, is there a way to do this? I tried setting the mH (mass of the higgs to a very large value, so that the hh intermediate pairs are not produced. Is that alright?
Thanks,
Harshal
