The initial temperature is obtained from the color string percolation model from the fit by the (two-component) Erlang distribution in the framework of a multisource thermal model. The excitation functions of several parameters such as the mean transverse momentum and initial temperature increase from 39 GeV to 13 TeV, which is considered in this work. The mean transverse momentum and initial temperature decrease (increase slightly or do not change significantly) with the increase of rapidity (centrality). Meanwhile, the mean transverse momentum of <math id=\"M9\"><mi>Y</mi><mfenced><mrow><mi>n</mi><mi>S</mi><mo>,</mo><mi>n</mi><mo>=</mo><mn>1</mn><mo>,</mo><mn>2</mn><mo>,</mo><mn>3</mn></mrow></mfenced></math> is larger than that of <math id=\"M10\"><mi>J</mi><mo>/</mo><mi>\u03c8</mi></math> and <math id=\"M11\"><mi>\u03c8</mi><mfenced><mrow><mn>2</mn><mi>S</mi></mrow></mfenced></math>, and the initial temperature for <math id=\"M12\"><mi>Y</mi><mfenced><mrow><mi>n</mi><mi>S</mi><mo>,</mo><mi>n</mi><mo>=</mo><mn>1</mn><mo>,</mo><mn>2</mn><mo>,</mo><mn>3</mn></mrow></mfenced></math> emission is higher than that for <math id=\"M13\"><mi>J</mi><mo>/</mo><mi>\u03c8</mi></math> and <math id=\"M14\"><mi>\u03c8</mi><mfenced><mrow><mn>2</mn><mi>S</mi></mrow></mfenced></math> emission, which shows a mass-dependent behavior."
