Determination of the ${\Lambda }_c^{+}$ spin via the reaction $e^{+}{e}^{-}\to {\Lambda }_c^{+}{\bar{\Lambda }}_c^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +484

We report on a comparison of two possible ${\Lambda }_c^{+}$ spin hypotheses, $J=\frac{1}{2}$ and $\frac{3}{2}$, via the process $e^{+}{e}^{-}\to {\Lambda }_c^{+}{\bar{\Lambda }}_c^{-}$, using the angular distributions of…
