“…Considering parity constraints, then the Charmoniumlike states are explained as admixtures of pure charmonium states. We compare our calculated mass spectrum(Cornell potential coupled with relativistic correction in the framework of pNRQCD) with experimentally determined masses and also with other theoretical approaches like relativistic model [100], LQCD [103], static potential [101] and non-relativistic model i.e considering only the Cornell potential [99,102]. We also perform a comparative study of present mass spectra with our previous result [99].…”

Mass spectrum of charmonium is computed in the framework of potential non-relativistic quantum chromodynamics. O(1/m) and O(1/m 2 ) relativistic corrections to the Cornell potential and spin-dependent potential have been added, and is solved numerically. New experimentally observed and modified positive and negative parity states like ψ(4230), ψ(4260), ψ(4360), ψ(4390), ψ(4660), χ c1 (4140) and χ c1 (4274) near open-flavor threshold have also been studied. We explain them as admixtures of S-D wave states and P-wave states. Apart from these states, some other states like X(3915), χ c1 (3872), ψ(3770) and ψ(4160) have been identified as 2 3 P 0 , 2 3 P 1 , 1 3 D 1 and 2 3 D 1 states. Subsequently, the electromagnetic transition widths and γγ, e + e − , light hadron and γγγ decay widths of several states are calculated at various leading orders. All the calculated results are compared with experimental and results from various theoretical models.

“…Similarly, we found that the maximum errors between our work and [15] are 0.03 GeV for S-states and P-states. In the same way, we calculate the maximum errors between our work and [16] and it was 0.02 GeV for S-states and 0.03 GeV for P-states. Hence, it can be seen that our calculated spectra are in close accordance with the PDG results and with the results of other theoretical studies, thus it can be concluded that this method gives satisfying results for predicting charmonium spectra.…”

“…By taking N = 200, = 20 fm , 0.4942, 0.1497 GeV , 1.1412 GeV and the charm quark mass 1.4619 GeV for S-states and for P-states, the spectra were summarized in Tables (1,2). We predict the masses of the twenty states of ̅ meson where we compared our theoretical predictions with those from [15,16,17]. By comparing present work with the recently published experimental data, we found that the maximum errors are 0.03 GeV for S-states and the maximum errors for P-states are 0.044 GeV.…”

“…We adopt the Cornell plus hyperfine correction plus spin-dependent terms model [14] to accurately obtain the ̅ spectrum of quark interactions for S and P states. Then, we compare our present work to other theoretical approaches [15,16] and experimental results [17] to stress the success of our model. On the other hand, the main motivation is to calculate the numerical values of coefficient β that is related to the root-mean-square radius of quarkonium for different states of ̅ meson.…”

We calculated the mass spectra of charmonium meson by using matrix method to make the predictions of ground and radially excited states of charmonium mesons via non-relativistic potential model. We compared our results with other theoretical approaches and recently published experimental data. The predictions are found to be in a good accordance with the latest experimental results of Particle data group and with the results of other theoretical approaches. Besides, we calculated the momentum width coefficients β of charmonium meson. Since, there are no experimental data for the momentum width coefficients β of charmonium meson yet. Consequently, our calculated coefficients β are compared with other theoretical studies and it is found to be in a good agreement with our results. The obtained results of coefficients β have implications for decay constants, decay widths and differential cross sections for charmonium system and generally for heavy mesons system. Our study is considered as theoretical calculation of some properties of charmonium meson.
