摘要:

AbstractIn this article we give a review of certain aspects of the present understanding of spectroscopy of heavy mesons and constituent quark masses in the light of non‐relativistic potential model approach motivated by quantum chromodynamics. We find that the one gluon exchange at short distance and colour‐confining interaction at large distance which is pure scalar (or scalarvector admixture with dominant scalar interaction) under the Lorentz transformation, can explain only partially the present data on1Pstates ofbbandbbstates. TheS‐wave data, that are available at present, however can be understood with both scalar confinement or scalar‐vector admixture with scalar‐dominant in

摘要:

AbstractThe previous work [1–3] was aimed at demonstrating the natural and intrinsic relationship between the fibered Finslerian framework and the Yang‐Mills gauge field theroy based on theSU(2)‐group of internal symmetries. In the present paper we continue the approach and find a particular solution for the Finslerian‐extended Einstein equations that relates to static and spherically symmetric gravitational field. Our treatment has been stimulated by the following question: does the Finslerian approach predict the effect of speed‐of‐light change under transition from one inertially moving laboratory to another? The accurate solution which answers this question in positive has

摘要:

AbstractWe study solutions of various quantum mechanical eigenvalue problems using the formalism of one dimensional supersymmetric quantum mechanics. The problems studied includes among other problems the non‐polynomial oscillator and the doubly anharmonic oscillator potentials. The solutions obtained here are of two types — exact analytical solutions and approximate solutions. The method of obtaining exact solutions have been shown to be general enough to be applied to a large class of potentials. The method of obtaining approximate solutions have been studied in details and their accuracy have been compared with exact numerical resu
