Parton Transverse Momentum and Orbital Angular Momentum Distributions
Abha Rajan, Aurore Courtoy, Michael Engelhardt +1
The quark orbital angular momentum component of proton spin, , can be defined in QCD as the integral of a Wigner phase space distribution weighting the cross product of the qu…
Towards a Direct Measurement of the Quark Orbital Angular Momentum Distribution
Simonetta Liuti, Aurore Courtoy, Michael Engelhardt +1
We discuss two different definitions of partonic orbital angular momentum given in the literature in terms of the Fourier transform of a Wigner distribution, , and a twist…
Beyond-Standard-Model Tensor Interaction and Hadron Phenomenology
Aurore Courtoy, Stefan Baessler, Martin Gonzalez-Alonso +1
We evaluate the impact of recent developments in hadron phenomenology on extracting possible fundamental tensor interactions beyond the standard model. We show that a novel class o…
Identification of Observables for Quark and Gluon Orbital Angular Momentum
Aurore Courtoy, Gary R. Goldstein, J. Osvaldo Gonzalez Hernandez +2
A new debate has recently arisen on the subject of orbital angular momentum in QCD, in particular on its observability and on its partonic interpretation. Orbital momentum can be d…
Phenomenology of at intermediate energy: the quark-hadron duality approach
A. Courtoy
In this contribution to the proceedings, we analyze the transition from perturbative and non- perturbative QCD embedded in the coupling constant. In the study of quark-hadron duali…
On the Observability of the Quark Orbital Angular Momentum Distribution
Aurore Courtoy, Gary R. Goldstein, J. Osvaldo Gonzalez Hernandez +2
We argue that due to Parity constraints, the helicity combination of the purely momentum space counterparts of the Wigner distributions -- the generalized transverse momentum distr…
