Operator Constraints for Twist-3 Functions and Lorentz Invariance Properties of Twist-3 Observables
Koichi Kanazawa, Yuji Koike, Andreas Metz +2
We investigate the behavior under Lorentz tranformations of perturbative coefficient functions in a collinear twist-3 formalism relevant for high-energy observables including trans…
Helicity Evolution at Small-x
Yuri V. Kovchegov, Daniel Pitonyak, Matthew D. Sievert
We construct small-x evolution equations which can be used to calculate quark and anti-quark helicity TMDs and PDFs, along with the structure function. These evolution equati…
Collinear Twist-3 Approach to Transverse Single-Spin Asymmetry in Proton-Proton Collision
Koichi Kanazawa, Andreas Metz, Yuji Koike +1
We present our recent analysis on the transverse single-spin asymmetry (SSA) in inclusive pion and direct-photon production in pp collisions for RHIC kinematics. The analysis inclu…
Single-spin asymmetries in the leptoproduction of transversely polarized hyperons
K. Kanazawa, A. Metz, D. Pitonyak +1
We analyze single-spin asymmetries (SSAs) in the leptoproduction of transversely polarized hyperons within the collinear twist-3 formalism. We calculate both the distribution a…
Transverse single-spin asymmetries in proton-proton collisions at the AFTER@LHC experiment
K. Kanazawa, Y. Koike, A. Metz +1
We present results for transverse single-spin asymmetries in proton-proton collisions at kinematics relevant for AFTER, a proposed fixed-target experiment at the Large Hadron Colli…
The RHIC SPIN Program: Achievements and Future Opportunities
Elke-Caroline Aschenauer, Alexander Bazilevsky, Markus Diehl +21
Time and again, spin has been a key element in the exploration of fundamental physics. Spin-dependent observables have often revealed deficits in the assumed theoretical framework…
