Proper definition and evolution of generalized transverse momentum distributions
Miguel G. Echevarria, Ahmad Idilbi, Koichi Kanazawa +4
We consider one of the most fundamental sets of hadronic matrix elements, namely the generalized transverse momentum distributions (GTMDs), and argue that their existing definition…
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…
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…
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…
