Precision measurement of the $Λ_{c}^{+}$ , $Ξ_{c}^{+}$ and $Ξ_{c}^{0}$ baryon lifetimes

LHCb collaboration, R. Aaij, C. Abellán Beteta +847

We report measurements of the lifetimes of the $Λ_{c}^{+}$ , $Ξ_{c}^{+}$ and $Ξ_{c}^{0}$ charm baryons using proton-proton collision data at center-of-mass energies of 7 and 8\tev, correspondin…
