Measurement of the properties of the ${\Xi }_b^{\ast 0}$ baryon

LHCb collaboration, R. Aaij, C. Abellán Beteta +731

We perform a search for near-threshold ${\Xi }_b^0$ resonances decaying to ${\Xi }_b^{-}{\pi }^{+}$ in a sample of proton-proton collision data corresponding to an integrated luminosity of 3 fb$^{-1…
