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 observables in hard-scattering hadronic processes within collinear factorization
D. Pitonyak
We review what is currently known about the transverse spin structure of hadrons, in particular from observables that can be analyzed within a collinear framework. These effects ha…
Longitudinal-transverse double-spin asymmetries in single-inclusive leptoproduction of hadrons
K. Kanazawa, A. Metz, D. Pitonyak +1
We analyze the longitudinal-transverse double-spin asymmetry in lepton-nucleon collisions where a single hadron is detected in the final state, i.e., $\vec{\ell}\,N^\uparrow \right…
Transverse single-spin asymmetries in from quark-gluon-quark correlations in the proton
K. Kanazawa, Y. Koike, A. Metz +1
We analyze the transverse single-spin asymmetry in direct photon production from proton-proton collisions, denoted , within collinear twist-3 factorization. We provide a cal…
