Helicity Evolution at Small x: Summary of Recent Developments
Yuri V. Kovchegov, Daniel Pitonyak, Matthew D. Sievert
We construct small- evolution equations which can be used to calculate quark and anti-quark helicity TMDs and PDFs, along with the structure function. These evolution equa…
Helicity Evolution at Small : Flavor Singlet and Non-Singlet Observables
Yuri V. Kovchegov, Daniel Pitonyak, Matthew D. Sievert
We extend our earlier results for the quark helicity evolution at small to derive the small- asymptotics of the flavor singlet and flavor non-singlet quark helicity TMDs and…
Small- asymptotics of the quark helicity distribution
Yuri V. Kovchegov, Daniel Pitonyak, Matthew D. Sievert
We construct a numerical solution of the small- evolution equations recently derived in \cite{Kovchegov:2015pbl} for the (anti)quark helicity TMDs and PDFs as well as the …
