Asymmetry of jet production in polarised pp collisions at RHIC and sign of Delta G
The jet production in (p) over right arrow-(p) over right arrow collisions at high energies is studied. Double-spin asymmetry A(LL) Of the process is calculated by using Monte Carlo code SPHINX. A possibility to discriminate the spin-dependent gluon distributions and to determine the sign of Delta G is discussed. The predictions for the longitudinal asymmetry A(LL) Of the jet and dijet production in the (p) over right arrow-(p) over right arrow collisions at RHIC energies have been made.
