| dc.description.abstract | We report a measurement of the D0 and Dþ lifetimes using D0 → K−πþ and Dþ → K−πþπþ decays reconstructed in eþe− → cc¯ data recorded by the Belle II experiment at the SuperKEKB asymmetricenergy eþe− collider. The data, collected at center-of-mass energies at or near the ϒð4SÞ resonance, correspond to an integrated luminosity of 72 fb−1. The results, τðD0Þ ¼ 410.5 1.1ðstatÞ 0.8ðsystÞ fs and τðDþÞ ¼ 1030.4 4.7ðstatÞ 3.1ðsystÞ fs, are the most precise to date and are consistent with previous determinations | en_US |
