Extraction of Pion Unpolarized Quark and Gluon Generalized Parton Distributions using Deep Neural-Networks
Satyajit Puhan, Shubham Sharma, Narinder Kumar
We present a deep neural-network (DNN) extraction of the pion unpolarized quark and gluon generalized parton distributions (GPDs) using the corresponding parton distribution functi…
Role of higher twist distributions in the tomography of proton
Navpreet Kaur, Shubham Sharma, Abi Jebarson A +1
We have studied the higher-twist distributions of the proton, including T-even and T-odd transverse momentum-dependent parton distributions (TMDs). Under the umbrella of the light-…
Moderate-to-Large- Gluon Helicity from Production at
Shubham Sharma, Alexey Aparin, Satyajit Puhan +2
We present a feasibility study of the longitudinal double-spin asymmetry in inclusive production in polarized proton-proton collisions at $\sqrt{s}\approx 27~\mathr…
Mechanical properties of proton in the momentum space
Navpreet Kaur, Shubham Sharma, Abi Jebarson A +1
We study the parametrization of the energy-momentum tensor for the case of a proton in momentum space in terms of gravitational transverse momentum-dependent distributions (TMDs).…
Extraction of Pion Unpolarized Quark Generalized Parton Distribution from Charge Form Factors
Satyajit Puhan, Shubham Sharma, Narinder Kumar +1
Based on a global fit to experimental measurements of the pion electromagnetic form factor and parton distribution functions (PDFs), we report a data-driven determination of the un…
Valence quark distribution of rho meson using light-front quark model
Satyajit Puhan, Shubham Sharma, Narinder Kumar +1
We investigate the partonic structure of the meson, the lightest spin- vector meson, within the light-front quark model (LFQM). To explore the sensitivity to model assumpti…
