Description

In the first part I shall present an update of the theoretical approach of [1] to the $K^{-} {}^{3} \text{He} \to \Lambda p n$ Reaction [2], adapting it to the most recent experimental results [3], where we show a good agreement with experiment using a picture based on chiral dynamics for the $\bar{K} N N$ Bound-State, which has a binding of about 20 MeV, shared by most theoretical approaches.
In the second part, I will present results based on the molecular approach to the recent $\Omega_c$ and pentaquark LHCb states, where a good reproduction on masses and widths is obtained for some oberved states, and others are predicted.
