A method to measure the absolute branching fractions of ${\Lambda }_c$ decays

Andrea Contu, Dorothea Fonnesu, Rudolf Gerhard Christiaan Oldeman +2

It is proposed to exploit the decay of the meson $B^{+}\to p{\pi }^{+}{\pi }^{+}{\bar{\Sigma }}_c^{--}$ and of its charge conjugate $B^{-}$ copiously produced at LHC to obtain a sample of ${\Lambda }_c$…
