A CLEAR TEST OF αs IN QCD AT ISR ENERGIES

  • We calculate the cross-section differences:
    (a) dσ(pp→Jet大PT+γ大PT+X)-dσ(pp→Jet大PT+γ大PT+X)
    (b) dσ(pp→2γ大PT+X)-dσ(pp→2γ大PT+X)
    (c) dσ(K-p→Jet大PT+γ大PT+X)-dσ(K+p→Jet大PT+γ大PT+X)
    (d) dσ(K-p→2γ大PT+X)-dσ(K+p→2γ大PT+X)
    (e) dσ(pp→2Jet大PT+X)-dσ(pp→2Jet大PT+X)
    and find that they are not affected by gluon and sea-quark distribution functions and various fragmentation functions. Comparing these results with the corresponding expe rimental data, one can accurately determine the ratio αs/α under the present experimental conditions.

Abstract: 

We calculate the cross-section differences:
(a) dσ(pp→Jet大PT+γ大PT+X)-dσ(pp→Jet大PT+γ大PT+X)
(b) dσ(pp→2γ大PT+X)-dσ(pp→2γ大PT+X)
(c) dσ(K-p→Jet大PT+γ大PT+X)-dσ(K+p→Jet大PT+γ大PT+X)
(d) dσ(K-p→2γ大PT+X)-dσ(K+p→2γ大PT+X)
(e) dσ(pp→2Jet大PT+X)-dσ(pp→2Jet大PT+X)
and find that they are not affected by gluon and sea-quark distribution functions and various fragmentation functions. Comparing these results with the corresponding expe rimental data, one can accurately determine the ratio αs/α under the present experimental conditions.
