Spinor Representations for Fields with any Spin: Lorentz Tensor Basis for Operators and Covariant Multipole Decomposition
Wim Cosyn, Frank Vera
This paper discusses a framework to parametrize and decompose operator matrix elements for particles with higher spin using chiral representations of the Lorentz group,…
Polarization options in inclusive DIS off tensor polarized deuteron
Wim Cosyn, Brandon Roldan Tomei, Alan Sosa +1
In the near future, the Jefferson Lab experiment will provide the second measurement of tensor polarized asymmetries in inclusive DIS on the deuteron. In this asymmetry, 4 in…
Spatial densities of the photon on the light front
Adam Freese, Wim Cosyn
The light front densities of momentum, angular momentum, and intrinsic pressure are calculated for the photon, both in the free case and at leading order in quantum electrodynamics…
Spatial densities of momentum and forces in spin-one hadrons
Adam Freese, Wim Cosyn
Densities associated with the energy-momentum tensor are calculated for spin-one targets. These calculations are done in a light front formalism, which accounts for relativistic ef…
u-Channel Color Transparency Observables
G. M. Huber, W. B. Li, W. Cosyn +1
We propose to study the onset of color transparency in hard exclusive reactions in the backward regime. Guided by the encouraging JLab results on backward pion and omega electro-pr…
Deeply virtual Compton scattering cross section at high Bjorken
F. Georges, M. N. H. Rashad, A. Stefanko +159
We report high-precision measurements of the Deeply Virtual Compton Scattering (DVCS) cross section at high values of the Bjorken variable . DVCS is sensitive to the Generaliz…
