Abstract: We rederive the small-$x$ evolution equations governing quark helicity distribution in a proton using solely an operator-based approach. In our previous works on the subject, the evolution equations were derived using a mix of diagrammatic… read more here.

Abstract: We study the small-x evolution equation for the gluon generalized parton distribution E_{g} of the nucleon. It is shown that E_{g} at vanishing skewness exhibits the Regge behavior identical to the Balitsky-Fadin-Kuraev-Lipatov pomeron despite its… read more here.
