DOI: 10.1007/jhep01(2021)136
Abstract: We present the leading-twist quark transverse momentum-dependent parton distribution functions (TMDs) for the spin-1 target, such as the ρ -meson, in the light-front framework. Specifically, we predict the TMDs in the light-front holographic model and… read more here.

DOI: 10.1007/s00601-018-1409-4
Abstract: QCD is not supersymmetrical in the traditional sense—the QCD Lagrangian is based on quark and gluonic fields, not squarks nor gluinos. However, its hadronic eigensolutions conform to a representation of superconformal algebra, reflecting the underlying… read more here.
