Query: Disentangling random thermal motion of particles and collective
  expansion of source from transverse momentum spectra in high energy
  collisions   In the framework of a multisource thermal model, we describe experimental
results of the transverse momentum spectra of final-state light flavour
particles produced in gold-gold (Au-Au), copper-copper (Cu-Cu), lead-lead
(Pb-Pb), proton-lead ($p$-Pb), and proton-proton ($p$-$p$) collisions at
various energies, measured by the PHENIX, STAR, ALICE, and CMS Collaborations,
by using the Tsallis-standard (Tsallis form of Fermi-Dirac or Bose-Einstein),
Tsallis, and two- or three-component standard distributions which can be in
fact regarded as different types of "thermometers" or "thermometric scales" and
"speedometers". A central parameter in the three distributions is the effective
temperature which contains information on the kinetic freeze-out temperature of
the emitting source and reflects the effects of random thermal motion of
particles as well as collective expansion of the source. To disentangle both
effects, we extract the kinetic freeze-out temperature from the intercept of
the effective temperature ($T$) curve as a function of particle's rest mass
($m_0$) when plotting $T$ versus $m_0$, and the mean transverse flow velocity
from the slope of the mean transverse momentum ($\langle p_T \rangle$) curve as
a function of mean moving mass ($\overline{m}$) when plotting $\langle p_T
\rangle$ versus $\overline{m}$.
