Abstract

The first measurement of the lifetime of the doubly charmed baryon Ξcc++ is presented, with the signal reconstructed in the final state Λc+K-π+π+. The data sample used corresponds to an integrated luminosity of 1.7 fb-1, collected by the LHCb experiment in proton-proton collisions at a center-of-mass energy of 13 TeV. The Ξcc++ lifetime is measured to be 0.256-0.022+0.024(stat)±0.014(syst) ps.
