| 英文摘要 | An improved value for the lifetime of the (anti-)hypertriton has been obtained using the data sample of Pb-Pb collisions at root s(NN) = 5.02 TeV collected by the ALICE experiment at the LHC. The (anti-)hypertriton has been reconstructed via its charged two-body mesonic decay channel and the lifetime has been determined from an exponential fit to the dN/d(ct) spectrum. The measured value, tau = 242(-38)(+34) (stat.) +/- 17 (syst.) ps, is compatible with representative theoretical predictions, thus contributing to the solution of the longstanding hypertriton lifetime puzzle.
