Probing Axial-Vector Charmonia ${\chi }_{c1}(1P)$ and ${\chi }_{c1}(2P)$

J. Y. Süngü, A. C. Jumasahatov

We investigate the ground-state heavy quarkonium ${\chi }_{c1}(1P)$ and its first excited state ${\chi }_{c1}(2P)$ with quantum numbers $J^{PC}=1^{++}$. The masses and decay constants of these…
