A linear potential in a light cone QCD inspired model
International Conference on Information Visualisation(2003)
摘要
The general equation from previous work is specialized to a linear potential
$V(r)=-a+F r$ acting in the space of spherically symmetric S wave functions.
The fine and hyperfine interaction creates then a $\frac1r$-dependence in the
effective potential energy equation and a position dependent mass $\widetilde
m(r)$ in the effective kinetic energy of the associated Schr\"odinger equation.
The results are compared with the available experimental and theoretical
spectral data on the $\pi$ and $\rho$. Solving the eigenvalue problem within
the analytically tractable Airy-function approach induces a certain amount of
arbitrariness (fudge factors). Despite of this, the agreement with experimental
data is good and partially better than other calculations, including Godfrey
and Isgur \cite{GodIsg85} and Baldicchi and Prosperi \cite{BalPro02}. The short
comings of the present model can be removed easily in more elaborate work.
