5 Apr 2015 | | Abstract: | In this work, we investigate the spectroscopy and decay rates of charmonia
within the framework of non-relativistic Schr"odinger equation by employing an
approximate inter quark-antiquark potential. The spin hyperfine, spin-orbit and
tensor components of the one gluon exchange interaction are employed to compute
the spectroscopy of the excited S states and few low-lying P and D waves. The
resultant wave functions at zero inter quark separation as well as some finite
separation are employed to predict the di-gamma, di-leptonic and di-gluon decay
rates of charmonia states. The predictions of the spectroscopy and the decay
widths are found to be in consistent with other model predictions as well as
with the known experimental values. | | Source: | arXiv, 1504.1103 | | Services: | Forum | Review | PDF | Favorites | |
