Description
The inner structure of hadrons nowadays remains elusive due to both experimental limitations and the complexity of analytical approaches. In this talk, I would like to share my previous research work about the spectroscopy and hadron structure, especially in light and heavy mesons in the light-front quark model (LFQM). Starting from heavy mesons, where mass spectra, decay constant, and M1 radiative transition are computed by considering the QCD-effective Hamiltonian such as screening effect and the harmonic oscillator basis as the trial wave function in the $1S$ - $3S$. As for light mesons, with similar parameters, M1 radiative transition as well as distribution amplitude are quite interested to explore due to the nature of the chiral symmetry breaking. These results show good agreement with both experimental data and other theoretical predictions.
