Precision measurements of the Lambda_c+ and D0 lifetimes

Abstract

We report new precision measurements of the lifetimes of the Lambda_c+ and D0 from SELEX, the charm hadro-production experiment at Fermilab. Based upon 1630 Lambda_c+ and 10210 D0 decays we observe lifetimes of tau[Lambda_c+] = 198.1 +- 7.0 +- 5.6 fs and tau[D0] = 407.9 +- 6.0 +- 4.3 fs
