Doubly heavy baryons at LHC
read the original abstract
The theoretical analysis of production, lifetime, and decays of doubly heavy baryons is presented. The lifetime of $\Xi_{cc}^{++}$ baryon recently measured by the LHCb Collaboration is used to estimate the lifetimes of other doubly heavy baryons. The production and the possibility of observation of $\Xi_{bc}$ baryon at LHC are discussed.

Study of doubly heavy baryon lifetimes
Lifetimes of Xi_cc++, Xi_cc+, Omega_cc+ are (2.67 ± 0.94, 0.47 ± 0.08, 1.79 ± 0.62) × 10^{-13} s and for Xi_bb0, Xi_bb-, Omega_bb- are (0.75 ± 0.11, 0.92 ± 0.15, 0.93 ± 0.15) × 10^{-12} s, with W-exchange driving larg...

Revisiting lifetimes of doubly charmed baryons
Updated predictions within the heavy quark expansion confirm the lifetime hierarchy τ(Ξ_cc^+) < τ(Ω_cc^+) < τ(Ξ_cc^++) with τ(Ξ_cc^++) = 0.32 ± 0.05 +0.08/-0.07 ps matching LHCb data and provide ratios for the other states.
