A reaction model for γ+p→J/ψ+p photoproduction, which exposes the cc¯ content of the photon in making the transition γ→cc¯+P→J/ψ and couples the intermediate cc¯ system to the proton's valence quarks via Pomeron (P) exchange, is used to

In this present study, we model Eckart-Hellmann Potential (EHP) to interact in a quark-antiquark system. The solutions of the Schrödinger equation are obtained with EHP using the Nikiforov-Uvarov method. The energy equation and normalized wave funct

Using Schrödinger’s formalism, we investigate the quantum eigenstates of the heavy mesons trapped by a point-like defect and by Cornell’s potential. One implements this defect to the model considering a spherical metric profile coupled to it. Fu

The solutions of the Schrödinger equation are obtained with an inversely quadratic Yukawa potential using the Nikiforov-Uvarov-Functional-analysis method. The energy spectrum and wave function were obtained in closed form. The energy equation was us

We calculate the mass spectrum of cc- meson by using matrix Numerov’s method to make the predictions of ground and radially excited states of charmonium mesons. The predictions are found to be in a good accordance with the latest experimental resul

Abstract Thermodynamic properties of heavy mesons are calculated within the framework of the N-dimensional radial Schrödinger equation. The Cornell potential is extended by including the quadratic potential plus the inverse of quadratic potential. T
