Description
A thermal model, based on the Tsallis distribution and blast-wave model, is proposed to compute hadron double-differential
spectra $d^{2}N/dp_{\rm T}dy$ in $pp$ (also high-energy $p\overline{p}$) collisions. It successfully describes the
available experimental data on pion and quarkonia ($\phi$, ${\rm J}/\psi$, $\psi({\rm 2S})$, ${\rm\Upsilon}$ family) production at energies from
$\sqrt{s}=$ 5 GeV to the LHC ones. Simple parametrizations for the $\sqrt{s}$ dependence of the model parameters are provided
allowing predictions for the yields of these particles at new collision energies.
