Description

The deuteron serves as an ideal system for investigating the strong interactions among quarks and gluons inside nuclear matter. Within the light-front framework, we treat the deuteron as an effective mixture of color-singlet–singlet and octet–octet clusters, and examine how these non-nucleonic components influence its properties.

In the Basis Light-Front Quantization approach, we extend the deuteron to the six-quark and six-quark-plus-one-dynamical-gluon Fock sectors. Under this truncation, we include the kinetic term, the light-front quark-gluon vertex interaction, and the relevant instantaneous interactions in the deuteron Hamiltonian. Using the deuteron light-front wave functions obtained by diagonalizing the light-front Hamiltonian, we study the contributions from different color components, as well as the electromagnetic form factors and parton distribution functions (PDFs).
