Teplov developed an approach to describe the meson quark model by establishing a mathematical quark series (harmonic quark series). With respect to the physical mesons, he made some basic hypotheses of his own and used the well-known theory of harmonic oscillation to construct a numerical mass series that obeys a rigid multiplicative pattern and allows the physical meson masses to be calculated accurately. We have found that his numerical quark series, i.e., their masses, has a fundamental relation to the reduced Max Planck constant ħand report on it in the present paper. This discovery is obviously a theoretical contribution to the correctness of Teplov’s harmonic quark model approach and at the same time a confirmation of the importance of this simple and powerful research work.展开更多

To be realistic such a model requires that the product of the structural coefficient of Lecher’s transmission lines σ and atomic number Z is constant. It was calculated that this electromechanical constant is 8.27756, and we call it structural constant. This constant builds the fine-structure constant 1/α = 137.036, and with permeability μ, permittivity ε and elementary charge e builds Plank’s constant h. This suggests the electromagnetic character of Planck’s constant. The relations of energy, frequency, wavelength and momentum of electromagnetic wave in an atom are also derived. Finally, an equation, similar to Schrodinger’s equation, was derived, with a clear meaning of the wave function, which represents the electric or magnetic field strength of the observed electromagnetic wave.展开更多

The predicted excited states for the B and Bs mesons are in very good agreement with results obtained by experiment. We assign B2（5747） and Bs2（5840） as the 1^3p2 state, B1（5721） and Bs1（5830） as the 1P1 state, B0（5732） as the 1^3P0 state, Bs1（5850） as the 1P1 state and B（5970） as the 23S1 state. We investigate the Regge trajectories in the （J,M2） and （nr,M2） planes with their corresponding parameters. The branching ratios for leptonic and radiative-leptonic decays are estimated for the B and Bs mesons. Our results are in good agreement with experimental observations as well as outcomes of other theoretical models.展开更多
