Abstract: We incorporate fine-structure corrections into the dynamical diquark model of multiquark exotic hadrons. These improvements include effects due to finite diquark size, spin-spin couplings within the diquarks, and most significantly, isospin-dependent couplings in the form… read more here.

DOI: 10.1007/jhep03(2019)009
Abstract: Based on the calculations using the lattice QCD by RBC-UKQCD collaboration and a large $N_c$ dual QCD, the resulted $\epsilon'/\epsilon$, which is less than the experimental data by more than a $2\sigma$ in the standard… 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.
