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

Abstract

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 charmonium states are computed using two-point QCD sum rule method by including quark, gluon and mixed condensates up to dimension-8. We compare our numerical results with the available experimental data as well as existing theoretical predictions in the literature.
