A novel technique for measuring the mass of the top quark that uses only the kinematic properties of its charged decay products is presented. Top quark pair events with final states with one or two charged leptons and hadronic jets are selected …

The jet fragmentation function of inclusive jets with transverse momentum ${p}_{\mathrm{T}}$ above $100\phantom{\rule{0.28em}{0ex}}\text{GeV}/c$ in PbPb collisions has been measured using reconstructed charged particles with ${p}_{\mathrm{T}}$ above $1\phantom{\rule{0.28em}{0ex}}\text{GeV}/c$ in a cone of radius 0.3 around the jet axis. A data sample of PbPb …
