First observation of the charmless decay of $\Xi_b^- \to pK^-K^-$ at LHCb
We present here the search for ${Ξ}^−_b$ and ${Ω}^−_b$ baryon decays to the charmless hadronic final states ph−h′− at the LHCb detector, where h(′) denotes a kaon or pion. The analysis is based on a sample of proton-proton collision data collected at centre-of-mass energies √s= 7 and 8 TeV, correspo...
