abstract

We study the correlation between the fermion composite system and quark spins by using the light-cone quark-diquark model. We do the calculations for $u$-quark and $d$-quark in the fermion system by considering the different polarization configrations of both. The contribution from scalar and axial-vector diquarks is taken into account. The overlap represenation of light-front wavefunctions is used for the calculations. The spin-spin correlations for $u$ and $d$ quarks are presented in transverse impact-parameter plane and transverse momentum plane as well.

Discussion (0). Continue with ORCID to comment.

  1. Six-dimensional light-front Wigner distributions of the proton

    hep-ph 2025-05 conditional novelty 6.0 of 10

    All 16 leading-twist six-dimensional light-front quark Wigner distributions for the proton are computed in a spectator-diquark model, extending earlier five-dimensional and unpolarized-only results.

  2. Study of kaon structure using the light-cone quark model

    hep-ph 2019-08 conditional novelty 5.0 of 10

    In the light-cone quark model, the kaon's up quark and strange antiquark have opposite spin-orbit correlations, with C_u_z = -0.234 and C_sbar_z = 0.176.
