The Cabibbo-allowed weak radiative decay ${\mathrm{\ensuremath{\Lambda}}}_{c}^{+}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Sigma}}}^{+}\ensuremath{\gamma}$ has been searched for in a sample of ${\mathrm{\ensuremath{\Lambda}}}_{c}^{+}{\overline{\mathrm{\ensuremath{\Lambda}}}}_{c}^{\ensuremath{-}}$ pairs produced in ${e}^{+}{e}^{\ensuremath{-}}$ annihilations, corresponding to an integrated luminosity of $4.5\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected with the BESIII detector at center-of-mass energies between 4.60 and 4.70 GeV. …

We report on a comparison of two possible ${\mathrm{\ensuremath{\Lambda}}}_{c}^{+}$ spin hypotheses, $J=\frac{1}{2}$ and $\frac{3}{2}$, via the process ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Lambda}}}_{c}^{+}{\overline{\mathrm{\ensuremath{\Lambda}}}}_{c}^{\ensuremath{-}}$, using the angular distributions of ${\mathrm{\ensuremath{\Lambda}}}_{c}^{+}$ decays into $p{K}_{S}^{0}$, $\mathrm{\ensuremath{\Lambda}}{\ensuremath{\pi}}^{+}$, ${\mathrm{\ensuremath{\Sigma}}}^{0}{\ensuremath{\pi}}^{+}$, and ${\mathrm{\ensuremath{\Sigma}}}^{+}{\ensuremath{\pi}}^{0}$. The data were recorded at $\sqrt{s}=4.6\text{ }\text{ }\mathrm{GeV}$ with the BESIII …
