Characteristics of multijet t/t events reconstructed by CMS in pp collisions at 13 TeV

We present here a characterization of the Monte Carlo samples used at CMS in the current LHC run (Run 2, sqrt(s)=13 TeV) and we compare them to the ones used in the previous run (Run 1, sqrt(s)=8 TeV). We then use these samples to reconstruct the top quark mass from the all-hadronic decay products a...

description We present here a characterization of the Monte Carlo samples used at CMS in the current LHC run (Run 2, sqrt(s)=13 TeV) and we compare them to the ones used in the previous run (Run 1, sqrt(s)=8 TeV). We then use these samples to reconstruct the top quark mass from the all-hadronic decay products and we compare the efficiencies of the standard reconstruction method when applied to the two different samples. We finally find a way to improve the efficiency for 13 TeV samples by using jets reconstructed with a different algorithm, the Cambridge-Aachen algorithm.
