DOI: 10.1088/0256-307x/42/8/080201

Abstract: In this paper, we study the ρ-meson electromagnetic form factors (EMFFs) within the framework of the light-front quark model. The physical form factors GC,M,Q(Q2) of the ρ-meson, as well as the charged square radius 〈r2〉,… read more here.

DOI: 10.1088/1674-1137/ad8ec3

Abstract: We investigated the ground state (1S), radially excited states (2S) and (3S), and orbitally excited state (1P) for the heavy charmonia ( ) and bottomonia ( ) mesons in the light-front quark model (LFQM). The… read more here.

DOI: 10.1103/physrevd.110.014020

Abstract: We investigate the structure of ground-state heavy mesons within the light-front quark model, utilizing wave functions derived from the single Gaussian ansatz (SGA) and the Gaussian expansion method (GEM). By performing a χ2 fit to… read more here.

DOI: 10.1103/physrevd.110.094021

Abstract: Using the variational principle, we systematically investigate the mass spectra and wave functions of both 1S and 2S state heavy pseudoscalar (P) and vector (V) mesons within the light-front quark model. This approach incorporates a… read more here.

DOI: 10.1103/physrevd.95.074009

Abstract: We present all the leading twist T-even TMDs in the light-front quark diquark model(LFQDM) and study the relations among them. The model contains both the scalar and vector diquarks with the light front wave functions… read more here.
