Pentaquark Search in the Strange Sector at ALICE at the LHC

The recent discovery of the hidden charm pentaquarks $P_{c}(4312)^{+}, P_{c}(4440)^{+},$ and $P_{c}(4457)^{+}$ by LHCb has reopened the question of whether pentaquarks exist in the strange sector. The strangeness enhancement, measured by ALICE as a function of increasing charged particle multiplicity even in $\rm{\textit{p}}$-$\rm{\textit{p}}$ collisions, further adds to the likelihood of observing a strange pentaquark state. Following analogous decay channels for the $P_{c}^{+}$ states into the strange sector, results for ${P_{s}}\rightarrow\phi\rm{\textit{p}}$, ${P_{s}}\rightarrow\Lambda{K}$, ${P_{s}}\rightarrow\Lambda{K}^{*}$, and ${P_{s}}\rightarrow\Sigma^{*}{K}$ through the invariant mass analysis in $\rm{\textit{p}}$-$\rm{\textit{p}}$ collisions at $\sqrt{s} = 13$ TeV are presented. Upper limits to the yields of ${P_{s}}$ states will be determined.
