Parton helicities at arbitrary x and Q2 in double-logarithmic approximation
B. I. Ermolaev
Description of spin-dependent hadronic processes at high energies in terms of parton helicities is a both effective and technically convenient means. In the present paper, we obtai…

Proton spin in double-logarithmic approximation
B. I. Ermolaev
Proton is a composite particle, so its spin S_P is made from the spins of the partons which the proton consists of. The discrepancy between S_P = 1/2 and the experimentally detecte…
