“…The considered photon PDFs [34,35,36] are all implemented with Λ − → c + X, ab → c + X, γb → c + X, and γγ → c + X, where a, b, c denote partons (quarks and gluons) and X represents the residual final-state partons, were found in Refs. [37], [38], [39,40], and [40,41], respectively. The NLO formalism for calculating the hadronic cross sections for e + e − annihilation, hadroproduction in pp collisions, and photoproduction in e ± p and e + e − collisions is described in Refs.…”

Using fragmentation functions for charged pions, charged kaons, and (anti)protons recently extracted from experimental data of e + e − annihilation at the Z-boson resonance and at centre-of-mass energy √ s = 29 GeV, we perform a global study of inclusive charged-hadron production in pp, γp, and γγ collisions at next-to-leading order in the parton model of quantum chromodynamics. Comparisons of our results with pp data from CERN SppS and the Fermilab Tevatron, γp data from DESY HERA, and γγ data from CERN LEP2 allow us to test the universality of the fragmentation functions predicted by the factorization theorem. Furthermore, we perform comparisons with e + e − -annihilation data from LEP2 so as to test the scaling violations predicted by the Altarelli-Parisi evolution equations.

“…They concluded that conventional factorization breaks down in the fragmentation case when isolation restrictions are imposed on the photon. Thus the cross section can no longer be written in the schematic factorized form 12) where the hard scattering cross section,σ ab→cX is infrared finite. They calculated the cross section for the process e + e − → γ + X and found it not to be infrared finite when the photon is isolated.…”

“…In this paper the isolated cross section was calculated using an approximate isolation method which was developed in [9] from a modification of the inclusive cross sections calculated in [11] for the direct part and in [12] for the fragmentation part. In [9] the basic idea of writing the isolated cross section as the inclusive cross section minus a subtraction piece, suggested by…”
