35. Nucleon structure in Minkowski space

Tobias Frederico (Instituto Tecnologico de Aeronáutica)

6/22/26, 2:00 PM

Light-Front Wave Functions and Hadron Structure

We will present results for the nucleon structure within light-front dynamics, adopting different interaction models. The framework is based on the solution of the Bethe-Salpeter equation projected onto the light-front for an effective interaction, as well as in 1+1 dimensions in ladder approximation, and is compared to previous calculations. Results for the parton distributions will be shown....

43. Transverse-momentum-dependent distributions and form factors of the pion and kaon in a self-consistent light-front quark model

Dr Ho-Meoyng Choi (Kyungpook National University)

6/22/26, 2:30 PM

Light-Front Wave Functions and Hadron Structure

We present a self-consistent light-front quark model for the pion and kaon based on the Bakamjian--Thomas (BT) construction and study their electromagnetic form factors,
unpolarized T-even transverse-momentum-dependent distributions (TMDs), and collinear parton distribution functions (PDFs). A consistent implementation of the invariant
mass $M_0$ in both hadronic matrix elements and Lorentz...

32. Spin-orbit correlation within heavy quarkonium

Xianghui Cao (University of Science and Technology of China)

6/22/26, 2:50 PM

Light-Front Wave Functions and Hadron Structure

The total spin of a hadron is a complex manifestation of its partonic constituents, arising from both the helicity of quarks and gluons, as well as their orbital angular momenta (OAM). Elucidating this spin structure at the partonic level remains a fundamental challenge in hadron physics. Analogous to spin-orbit correlations in atomic and nuclear systems, the interplay between spin and OAM is...

23. Interpolating Instant and Light-Front Dynamics

Prof. Chueng-Ryong Ji (North Carolina State University)

6/22/26, 3:10 PM

Light-Front Wave Functions and Hadron Structure

Relativistic quantum invariance plays prominent roles in the study of quantum field theories, typically QED and QCD. We utilize the idea of interpolating the instant form dynamics (IFD) and the light-front dynamics (LFD) to realize the relativistic quantum invariance of QED and QCD. Reviewing the connection between LFD and IFD using the idea of interpolating the two different forms of the...

36. Reappraising Light Front Densities

Adam Freese (Jefferson Lab)

6/22/26, 4:15 PM

Light-Front Wave Functions and Hadron Structure

Light front densities have long been promoted as constituting true internal hadron densities. A big selling point is that light front uniquely permits transverse localization and a clean separation between the barycentric and internal degrees of freedom many-body systems, both of which follow from the light front's realization of the Poincaré group's Galilean subgroup. Rather than eliminating...
