| Abstract | A measurement of the ÃÂÃÂ++cc mass is performed using data collected by the LHCb experiment between 2016 and 2018 in pp collisions at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.6 fbâÃÂÃÂ1. The ÃÂÃÂ++cc candidates are reconstructed via the decay modes ÃÂÃÂ++ccâÃÂÃÂÃÂÃÂ+cKâÃÂÃÂÃÂÃÂ+ÃÂÃÂ+ and ÃÂÃÂ++ccâÃÂÃÂÃÂÃÂ+cÃÂÃÂ+. The result, 3621.55 ÃÂñ 0.23 (stat) ÃÂñ 0.30 (syst) MeV/c2, is the most precise measurement of the ÃÂÃÂ++cc mass to date. |
