Description

We study the jet-mass distribution for jets produced in hadron-hadron collision in QCD. In order to obtain reliable phenomenological results we resum to all-order in perturbation theory those contributions coming from collinear and soft gluons. Beyond the leading-logarithmic accuracy the resummation is made more complicated by the presence of non-global logarithms and logarithms related to the choice of the jet-algorithm. We apply our calculation to the interesting case of the jet-mass in Z+jet events, which is of great phenomenological interest for boosted Higgs.
