Deconfinement and degrees of freedom in pp and $$A-A$$ collisions at LHC energies

We present the extraction of temperature by analyzing charged particle transverse momentum spectra in lead–lead (Pb–Pb) and proton–proton (pp) collisions at LHC energies from ALICE Collaboration using Color String Percolation Model (CSPM). From measured energy density $${\varvec{\varepsilon }}$$ T dimensionless quantity }/}T^{4}$$ is obtained to get degrees freedom (DOF), }}/T^{4} = \hbox {DOF} \,{ \pi ^{2}}/30$$ . observe for first time a two-step behavior increase DOF, characteristic deconfinement, above hadronization $$\sim $$ 210 MeV both Pb–Pb pp sudden ideal gas value 47$$ corresponding three quark flavors case collisions.
