Search for the ${\Lambda }_b\to \Lambda {\eta }^{\prime }$ and ${\Lambda }_b\to \Lambda \eta$ decays with the LHCb detector

LHCb collaboration, R. Aaij, B. Adeva +716

A search is performed for the as yet unobserved baryonic ${\Lambda }_b\to \Lambda {\eta }^{\prime }$ and ${\Lambda }_b\to \Lambda \eta$ decays with 3$f{b}^{-1}$ of proton-proton collision data recorded by the…
