Kaon T-even transverse-momentum-dependent distributions and form factors in a self-consistent light-front quark model
Yongwoo Choi, Ahmad Jafar Arifi, Ho-Meoyng Choi +1
We present a self-consistent light-front quark model (LFQM) for the kaon based on the Bakamjian--Thomas (BT) construction and apply it to the electromagnetic and scalar form factor…
The (3+1)-dimensional scalar field model analysis of beam spin asymmetry in the electroproduction of a scalar meson off a scalar target
Andrew Lundeen, Chueng-Ryong Ji, Yongwoo Choi +1
We explore exclusive scalar meson electroproduction off a scalar target in the (3+1)-dimensional scalar field model. This model analysis is a straightforward extension of the previ…
Gravitational form factors of the pion in the self-consistent light-front quark model
Yongwoo Choi, Hyeon-Dong Son, Ho-Meoyng Choi
We present a self-consistent light-front quark model (LFQM) analysis of the pion's gravitational form factors (GFFs), incorporating the Bakamjian-Thomas (BT) construction consisten…
Nucleon and singly heavy baryons from the QCD instanton vacuum
Yongwoo Choi, Hyun-CHul Kim
We construct an effective chiral theory for the nucleon, based on the low-energy effective QCD partition function from the QCD instanton vacuum. We fully consider the momentum-depe…
