Relativistic harmonic oscillator model for quark stars
The relativistic harmonic oscillator (RHO) model of hadrons is used to study quark stars. The massradius relationship is obtained and compared with bag model of quark star, using Tolman-OppenheimerVolkoff equation. In this model, the outward degenerate pressure due to discrete Landau levels and Landau degeneracy balances the inward gravitational pressure. Where as in bag model the degenerate pr...
متن کاملPseudospin symmetry and the relativistic harmonic oscillator
A generalized relativistic harmonic oscillator for spin 1/2 particles is studied. The Dirac Hamiltonian contains a scalar S and a vector V quadratic potentials in the radial coordinate, as well as a tensor potential U linear in r. Setting either or both combinations S=S+V and D=V−S to zero, analytical solutions for bound states of the corresponding Dirac equations are found. The eigenenergies a...
متن کاملRelativistic Ladder Operators for the Three-Dimensional Harmonic Oscillator
The quantum constraint equations for a relativistic three-dimensional harmonic oscillator are shown to find concise expression in terms of Lorentz covariant ladder operators. These ladder operators consist of two conjugate 4-vectors that are each constrained to generate three linearly independent combinations of ladder operator components for raising and lowering the eigenstates of the oscillat...
متن کامل0 Duality in the non - relativistic harmonic oscillator quark model in the Shifman - Voloshin limit : a pedagogical example
The detailed way in which duality between sum of exclusive states and the free quark model description operates in semileptonic total decay widths, is analysed. It is made very explicit by the use of the non relativistic harmonic oscillator quark model in the SV limit, and a simple interaction current with the lepton pair. In particular, the Voloshin sum rule is found to eliminate the mismatche...
متن کاملCovariant oscillator quark model for baryons
An analytic resolution of the covariant oscillator quark model for baryons is presented. Our harmonic potential is a general quadratic potential which can simulate both a ∆-shaped configuration or a simplified Y configuration where the junction is located at the centre of mass. The addition of new terms simulating the one gluon exchange process and the quark self-energy is discussed, and a comp...
