The measurement of the production of $\\rm{f}_{0}(980)$ in inelastic pp collisions at $\\sqrt{s}$ = 5.02 TeV is presented. This is the first reported measurement of inclusive $\\rm{f}_{0}(980)$ yield at LHC energies. The production is measured at midrapidity, $\\left | y \\right | < 0.5$, in a wide transverse momentum range, $0<p_{\\rm{T}}<16$ GeV/$c$, by reconstructing the resonance in the $\\rm{f}_{0}(980) \\rightarrow\\pi^{+}\\pi^{-}$ hadronic decay channel using the ALICE detector. The $p_{\\rm{T}}$-differential yields are compared to those of pions, protons and $\\phi$ mesons as well as to predictions from the HERWIG~7.2 QCD-inspired Monte Carlo event generator and calculations from a coalescence model that uses the AMPT model as an input. The ratio of the $p_{\\rm{T}}$-integrated yield of $\\rm{f}_{0}(980)$ relative to pions is compared to measurements in $\\mathrm{e}^{+}\\mathrm{e}^{-}$ and pp collisions at lower energies and predictions from statistical hadronisation models and HERWIG~7.2. A mild collision energy dependence of the $\\rm{f}_{0}(980)$ to pion production is observed in pp collisions from SPS to LHC energies. All considered models underpredict the $p_{\\rm{T}}$-integrated 2$\\rm{f}_{0}(980)/(\\pi^{+}+\\pi^{-})$ ratio. The prediction from the canonical statistical hadronisation model assuming a zero total strangeness content of $\\rm{f}_{0}(980)$ is consistent with the data within 1.9$\\sigma$ and is the closest to the data. The results provide an essential reference for future measurements of the particle yield and nuclear modification in p-Pb and Pb-Pb collisions, which have been proposed to be instrumental to probe the elusive nature and quark composition of the $\\rm{f}_{0}(980)$ scalar meson.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.136307.v1/t1","@type":"Dataset","description":"$p_{\\rm T}$-differential yields of $f_{0}(980)$ at midrapidity in the inelastic pp collisions at $\\sqrt(s)$ = 5.02 TeV.
