Asymmetry of p(->)+p(->)->gamma+jet+X process and problem of Delta G
G. P. Skoro, M. V. Tokarev
Abstract
The gamma +jet production in p(->)-p(->) collisions at high energies is studied. Double-spin asymmetry ALL of the process is calculated by using Monte Carlo code SPHINX. The predictions for ALL of the gamma +jet production in the p(->)-p(->) collisions using the spin-dependent gluon distributions with positive and negative sign of ΔG(x,Q2) are made at RHIC energies. A possibility to extract the spin-dependent gluon distributions Delta G at STAR experiment and to discriminate between different theoretical scenarios is discussed.
