TESTING GLUON DISTRIBUTION FUNCTION OF HADRONS IN LARGE PT PROCESS WITH DIRECT PHOTON EMISSION

  • In this paper we disscuse disscuse the physicsical aspect of cross-section differences ΔABcγ=dσ(AB→cγX)-dσ(AB→cγX) and give the simple rules to select the elementary subprocesses which contribute to cross-section differences.
    We bind a way to test the gluon distribution functions of hadrons through the measurement of cross-section difference or combination of cross-section differences in the large PT process with direct photon emission. Moreover we obtain simple relations between each combination of cross-sections and the corresponding gluon distribution functions of proton, neutron, pion and daon:
    Gp8(x)/(Δpphγ－Δpphγ)=Gn8(x)/(Δpphγ)=Gπ8(x)/(Δπ+phγ+Δπ－phγ=GK8(x)/(ΔK+phγ+ΔK－phγ)which are expected to be test in experiment.

Abstract: In this paper we disscuse disscuse the physicsical aspect of cross-section differences ΔABcγ=dσ(AB→cγX)-dσ(AB→cγX) and give the simple rules to select the elementary subprocesses which contribute to cross-section differences.
We bind a way to test the gluon distribution functions of hadrons through the measurement of cross-section difference or combination of cross-section differences in the large PT process with direct photon emission. Moreover we obtain simple relations between each combination of cross-sections and the corresponding gluon distribution functions of proton, neutron, pion and daon:
Gp8(x)/(Δpphγ－Δpphγ)=Gn8(x)/(Δpphγ)=Gπ8(x)/(Δπ+phγ+Δπ－phγ=GK8(x)/(ΔK+phγ+ΔK－phγ)which are expected to be test in experiment.
