The production of the $f_{0}(980)$ meson at high energies is not wellunderstood. We investigate two different potential mechanisms for inclusivescalar meson production in the $k_t$-factorization approach: color-singletgluon-gluon fusion and color evaporation model. The $\gamma^* \gamma^* \tof_0(980)$ form factor(s) can be constraint from the $f_0(980)$ radiative decaywidth. The $g^* g^* \to f_0(980)$ form factors are obtained by a replacement of$\alpha_{\rm{em}}$ electromagnetic coupling constant by $\alpha_{\rm{s}}$strong coupling constant and appropriate color factors. The form factors forthe two couplings are parametrized with a function motivated by recent resultsfor scalar quarkonia. The differential cross sections are calculated in the$k_t$-factorization approach with modern unintegrated gluon distributions.Unlike for quarkonia it seems rather difficult to describe a preliminary ALICEdata for inclusive production of $f_0(980)$ exclusively by the color singletgluon-gluon fusion mechanism. Two different scenarios for flavor structure of$f_0(980)$ are considered in this context. We consider also mechanism of fusionof quark-antiquark associated with soft gluon emission in a phenomenologicalcolor evaporation model (CEM) used sometimes for quarkonium production. Here weuse $k_t$-factorization version of CEM to include higher-order contributions.In addition, for comparison we consider also NLO collinear approach with $q\bar{q} q$ and $q \bar{q} g$ color octet partonic final states. Both approacheslead to a similar result. However, very large probabilities are required todescribe the preliminary ALICE data. The pomeron-pomeron fusion mechanism isalso discussed and results are quantified.
