The (anti-)hypertriton has been identified via its charged two-body mesonic decay channel and the lifetime has been determined with an exponential fit to the d$N$/d($c$t) spectrum. The measured value, $\\tau$ = 242$^{+34}_{-38}$ (stat.) $\\pm$ 17 (syst.) ps, is in agreement within 1$\\sigma$ with the free $\\Lambda$ lifetime. This result is compatible with all the available theoretical predictions, thus contributing to the solution of the longstanding hypertriton lifetime puzzle.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.91130.v1/t1","@type":"Dataset","description":"(Hypertriton + Anti-Hypertriton)dN/d(ct) distribution.","name":"Table 1"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1743989?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/91130"}],"inLanguage":"en","name":"$^3_\\Lambda\\mathrm{H}$ and $^3_{\\overline{\\Lambda}}\\mathrm{\\overline{H}}$ lifetime measurement in Pb-Pb collisions at $\\sqrt{s_{\\mathrm{NN}}} = $ 5.02 TeV via two-body decay","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1743989?version=1","version":1}
