One Gluon splitting
Asked by
Debjyoti Bardhan
Hello,
I was interested in a process in which two gluons are produced and then only one of them splits to two b quarks. So, if g1 and g2 are two gluons (I am just labelling them for convenience), I want
p p > g1 g2, g1 > b b~
or
p p > g1 g2, g2 > b b~
Unfortunately, when I use
p p > g g, g > b b~, both gluons split to the di-bottom state.
I have tried p p > g g, g > b b~ QCD<=3. (max. order of QCD coupling in the amplitude is 3), but to no avail.
The process p p > g b b~ obviously also includes the process where the gluon is radiated off a bottom quark line, so this doesn't work either.
Kindly help.
Thanks,
Debjyoti
