Measurement of Singly Cabibbo Suppressed Decays ${\Lambda }_c^{+}\to p{\pi }^{+}{\pi }^{-}$ and ${\Lambda }_c^{+}\to p{K}^{+}{K}^{-}$

BESIII collaboration, M. Ablikim, M. N. Achasov +432

Using 567 $p{b}^{-1}$ of data collected with the BESIII detector at a center-of-mass energy of $\sqrt{s}=$ 4.599 $GeV$, near the ${\Lambda }_c^{+}{\Lambda }_c^{-}$ threshold, we study the singly C…
