Description

The spin content of the proton as a function of quark and gluon helicities and orbital angular momentum can be described in terms of integrals of parton distributions. These integrals, from x=0 to 1, require in particular a precise understanding of the asymptotic behavior of said distributions in the low x limit. We will discuss the resummation of double logarithms which governs this behavior and its consequences on the proton spin problem.
