Search for the doubly heavy baryons $\it{\Xi}_{bc}^{\rm0}$ and $\it{\Omega}_{bc}^{\rm0}$ decaying to $\it{\Lambda_{c}^{+}\pi^{-}}$ and $\it{\Xi_{c}^{+}\pi^{-}}$ / LHCb Collaboration
A search for the doubly heavy baryons $\it{\Xi}_{bc}^{\rm0}$ and $\it{\Omega}_{bc}^{\rm0}$ is performed using $pp$ collision data collected with the LHCb experiment from 2016 to 2018 at a centre-of-mass energy of $13TeV$, corresponding to an integrated luminosity of 5.2$fb^{-1}$. [...]
