Light sea-quark flavor asymmetry and angular momentum of the nucleon in a scalar-vector spectator model
Parashmani Thakuria, Madhurjya Lalung, Jayanta Kumar Sarma
We present a light-front spectator model that describes the proton as an active sea antiquark paired with a composite scalar-vector spectator. Using a spatial profile based on soft…

Exploring twist-3 chiral even generalized parton distributions of light sea quarks in the proton using the light front model
Parashmani Thakuria, Madhurjya Lalung, Jayanta Kumar Sarma
We develop a light-front model of the proton to investigate the twist-3 chiral-even generalized parton distributions (GPDs) of light sea quarks. In this framework, sea quarks are t…

Subleading Twist-3 Gluon Generalized Parton Distributions in the Light-Front Model
Parashmani Thakuria, Madhurjya Lalung, Jayanta Kumar Sarma
We present a calculation of the twist-3 generalized parton distributions (GPDs) for gluons in the proton. Our analysis is performed within a light-front constituent model where the…
