Phase-constrained ${\Sigma }^{\ast }$ spectroscopy in the pure-$I=1$ reactions $K_{L}p\to {\pi }^{+}{\Sigma }^0$ and $K_{L}p\to {\pi }^{+}\Lambda$

Low-energy $\bar{K}N$ scattering provides direct access to strange-baryon spectroscopy, but conventional charged-kaon reactions mix the $I=0$ and $I=1$ amplitudes. Motivated by the…
