“…7, but it shows the de-pendences of initial temperature (a)(c) T i1 and (b)(d) T i2 on (a)(b) m 0 and (c)(d) C, where T i1 (T i2 ) is obtained by the root-mean-square p T divided by √ 2, i.e. p 2 T 1 /2 ( p 2 T 2 /2) according to [37,38,39]. The symbols represent the results obtained from the fitting functions (Eqs.…”

The transverse momentum spectra of charged particles produced in proton(deuteron)-nucleus and nucleus-nucleus collisions at high energies are analyzed by the Hagedorn thermal model and the standard distribution in terms of multi-component. The experimental data measured in central and peripheral gold-gold (Au-Au) and deuteron-gold (d-Au) collisions by the PHENIX Collaboration at the Relativistic Heavy Ion Collider (RHIC), as well as in central and peripheral lead-lead (Pb-Pb) and proton-lead (p-Pb) collisions by the ALICE Collaboration at the Large Hadron Collider (LHC) are fitted by the two models. The initial, effective, and kinetic freeze-out temperatures are then extracted from the fitting to the transverse momentum spectra. It is shown that the initial temperature is larger than the effective temperature, and the effective temperature is larger than the kinetic freezeout temperature. The three types of temperatures in central collisions are comparable with those in peripheral collisions, and those at the LHC are comparable with those at the RHIC.

The rapidity dependent transverse momentum spectra of heavy quarkonia ( ⁄ and Υ mesons) produced in small collision systems such as proton-proton (pp) and proton-lead (p-Pb) collisions at center-of-mass energy (per nucleon pair) NN ( ) s s  5-13 TeV are described by a two-component statistical model which is based on the Tsallis statistics and inverse power-law. The experimental data measured by the LHCb Collaboration at the Large Hadron Collider (LHC) are well fitted by the model results. The related parameters are obtained and the dependences of parameters on rapidity are analyzed.

“…This is quite usual when one wishes to particularly investigate the role of extra material rather than geometrical terms in gravity. Anyhow, f (R, T ) models with correction terms on both sides of Einstein's field equations can be seen in [56,70,75,78] and also [91,92,93]. Furthermore, for an f (R, T ) model containing a strong coupling between geometry and matter, such as f (R, T ) = R + αRT , with constant α, check [94].…”

The f (R, T ) gravity field equations depend generically on both the Ricci scalar R and trace of the energy-momentum tensor T . Within the assumption of perfect fluids, the theory carries an arbitrariness regarding the choice of the matter lagrangian density L, not uniquely defined. Such an arbitrariness can be evaded by working with the trace of the theory field equations. From such an equation, one can obtain a form for L, which does not carry the arbitrariness. The obtained form for L shows that the f (R, T ) gravity is unimodular. A new version of the theory is, therefore, presented and forthcoming applications are expected.
