The measurement is performed with the ALICE detector in high-multiplicity triggered pp collisions at $\\sqrt{s} = 13$ TeV. The $\\Sigma^{+}$ hyperons are reconstructed using a missing-mass approach in the decay channel to $\\textrm{p} + \\uppi^0$ with $\\uppi^0\\rightarrow\\upgamma\\upgamma$, while both $\\Sigma^{+}$ and protons are identified using a machine learning approach. These techniques result in a high reconstruction efficiency and purity, which allows the measurement of the p-$\\Sigma^{+}$ correlation function for the first time. Thanks to the high significance achieved in the p-$\\Sigma^{+}$ correlation signal, it is possible to discriminate between the predictions of different models of the N-$\\Sigma$ interaction and to accomplish a first determination of the p-$\\Sigma^{+}$ scattering parameters.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.168411.v1/t1","@type":"Dataset","description":"Raw correlation function $C(k^{*})$ of $\\textrm{p}-\\Sigma^+$ and $\\bar{\\textrm{p}}-\\bar{\\Sigma}^-$ in high-multiplicity triggered pp collisions at $\\sqrt{{s}}=13$ TeV.
