Origin of the nucleon gravitational form factor : Exposition in light-front holographic QCD
Xianghui Cao, Bheemsehan Gurjar, Chandan Mondal +2
Recent lattice QCD simulations and phenomenological models indicate that the nucleon's gravitational form factor remains remarkably small at finite momentum transfer .…
Near-threshold heavy quarkonium photoproduction in a light-front spectator model
Amrita Sain, Bheemsehan Gurjar, Chandan Mondal
The near-threshold photo- and electroproduction of heavy vector quarkonia off the proton provides direct access to its gluonic structure. In particular, the cross section for $J/Ψ…
Gluon generalized transverse momentum dependent parton distributions and Wigner functions of the Proton
Dipankar Chakrabarti, Bheemsehan Gurjar, Asmita Mukherjee +1
We present a calculation of the leading-twist (twist-2) generalized transverse momentum distributions (GTMDs) for unpolarized and longitudinally polarized gluons in the proton, usi…
Gluon gravitational form factors of the proton in a light-front spectator model
Amrita Sain, Poonam Choudhary, Bheemsehan Gurjar +3
We calculate the gluon gravitational form factors (GFFs) of the proton using a light-front spectator model based on soft-wall AdS/QCD, where the active parton is a gluon. The model…
-meson spectroscopy and diffractive production using two Schrödinger like equations on the light-front
Bheemsehan Gurjar, Chandan Mondal, Satvir Kaur
We show that the holographic Schrödinger equation of light-front chiral QCD, together with the 't Hooft equation of (1+1)-dimensional QCD in the large limit, can simultaneou…
Azimuthal spin asymmetries in pion-polarized proton induced Drell-Yan process at COMPASS using holographic light-front QCD
Bheemsehan Gurjar, Chandan Mondal
We compute all the leading-twist azimuthal spin asymmetries in the pion-proton induced Drell-Yan process. These spin asymmetries arise from convolutions of the leading-twist transv…
