Abstract

The one- and two-spin asymmetries in a collision of polarized protons pp → (γ*,z) + X are studied in the present work within the framework of the quantum chromodynamics and the electroweak interaction. We use the method of helical amplitudes. Analytical expressions for one-spin A L and two-spin A LL asymmetries are derived and their dependences on the transverse momentum of the lepton pair are investigated for three values of invariant mass of the lepton pair. The results obtained allow the spin structure of the proton to be investigated.
