A New Description of Transverse Momentum Spectra of Identified Particles Produced in Proton-Proton Collisions at High Energies

Figure 6

(a) The invariant cross-sections of diphotons and heavy-flavor dielectrons produced in collisions at 13 TeV. Different symbols represent different particles in different ranges measured by the ATLAS [37] and ALICE [38] Collaborations and scaled by different factors marked in the panel. The dotted and dashed curves are our fitted results by using Eqs. (7) and (9), respectively. (b) The ratio of data to fit obtained from Eq. (7). (c) The ratio of data to fit obtained from Eq. (9).
