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 …
Transverse Spin and Classical Gluon Fields: Combining Two Perspectives on Hadronic Structure
Matthew D. Sievert
In recent decades, the spin and transverse momentum of quarks and gluons were found to play integral roles in the structure of the nucleon. Simultaneously, the onset of gluon satur…
