Abstract
The first measurement of the lifetime of the doubly charmed baryon is presented, with the signal reconstructed in the final state . The data sample used corresponds to an integrated luminosity of , collected by the LHCb experiment in proton-proton collisions at a center-of-mass energy of 13 TeV. The lifetime is measured to be .
