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

Figure 7

Various pion spectra with different parameters in Eqs. (7) and (9). From the upper panels ((a)–(c)) to the middle panels ((d)–(f)) and then to the lower panels ((g)–(i)), changes from 0.1 GeV to 0.15 GeV and then to 0.2 GeV. From the left panels ((a), (d), (g)) to the middle panels ((b), (e), (h)) and then to the right panels ((c), (f), (i)), changes from 5 to 10 and then to 15. In each panel, the solid, dotted, dashed, and dot-dashed curves without (with) open circles are obtained by , respectively, from Eq. (7) (Eq. (9)).
