Figure 15

Invariant mass spectra of $\Lambda^{+}_{c}\to$pK$^{-}\pi^{+}$ using n$_{\sigma}$ PID, minimum-$\sigma$ PID and Bayesian PID for (left) $2< \pt< 6$ GeV/$c$ and (right) $3< \pt< 4$ GeV/$c$. Due to the low statistical significance, it was not possible to extract a stable signal for n$_{\sigma}$ PID for $3< \pt< 4$ GeV/$c$, therefore this fit and its results are not shown.
