Abstract
The mass spectrum of the D wave mesons has been investigated and compared in the frame work of non-relativistic (NRQM) and relativistic (RHM) quark models. The NRQM Hamiltonian used in the investigation has kinetic energy, confinement potential, one-gluon-exchange potential (OGEP) and instanton induced quark-antiquark interaction (III) whereas RHM Hamiltonian includes the Lorentz scalar plus a vector harmonic-oscillator potential, the confined-one-gluon-exchange potential (COGEP) and III. The calculated D wave meson masses are in agreement with the experimental D wave meson masses. The respective role of III, OGEP and COGEP in the D wave meson spectrum is discussed and compared between two models
