how to find the forward jet

Asked by lyb on 2018-10-26

Dear ma5 team,

I am simulating in MG5 the SM process p p > t h j, (t > w+ b, w+ > j j), h > b b~ with pythia8 and Delphes. So the final states has more than three jets and three b-jet. Among these three light jets, two comes from the t-> Wb-> jjb decay and one is the forward jet. My question is when I generated many processes (including p p > t t~ with hadronic decay from top) after pythia and Delphes, how can I find which jet in the final states is the forward jet in ma5 -R mode?

Thanks.

Hi,

You can for instance order the jet by pseudorapidity and take the one with the greatest.

Regards,

Benjamin
