  The differential cross-section in squared momentum transfer of $\rho$,
$\rho^0$, $\omega$, $\phi$, $f_{0}(980)$, $f_{1}(1285)$, $f_{0}(1370)$,
$f_{1}(1420)$, $f_{0}(1500)$, and $J/\psi$ produced in high energy virtual
photon-proton ($\gamma$$^{*} p$), photon-proton ($\gamma p$), and proton-proton
($pp$) collisions measured by the H1, ZEUS, and WA102 Collaborations are
analyzed by the Monte Carlo calculations. In the calculations, the Erlang
distribution, Tsallis distribution, and Hagedorn function are separately used
to describe the transverse momentum spectra of the emitted particles. Our
results show that the initial- and final-state temperatures increase from lower
squared photon virtuality to higher one, and decrease with increasing of
center-of-mass energy.
