Revisiting lifetimes of doubly charmed baryons
Abstract We present updated predictions for lifetimes of doubly charmed baryons, within the heavy quark expansion, including available NLO α s contributions and newly-computed terms in the 1/m c series. Our improved results confirm the expected hierarchy τ Ξ cc + < τ Ω cc + < τ Ξ cc + + , $$ \...
