MUONS VS JETS AT 100 TEV

Can we do something competitive with jets? What is the reach in di-jet searches compared to di-lepton ones? Are there interesting cases where jets can give the highest reach?

DI-JETS RESONANCES AT 100 TEV

For different width hypotheses and taking into account the expected resolution one can focus the analysis into windows of size around the signal mass hypothesis
