Skyrmion的相对论波动方程

A Relativistic Wave Equation for the Skyrmion

S. G. Rajeev

摘要:

我们提出了一个相对论不变的Skyrme孤子的波动方程。它是空间$R^{1,3}\times S^3$上的微分方程,在洛伦兹群和同位旋下是不变的。在$SU(2)\approx S^3$中取值的内部变量描述了孤子的取向。自旋和同位旋都等于$j={1\over 2},{3\over 2}...$的粒子的质量被预测为$M=m\sqrt{1+K_2j(j+1)\over 1+K_1j(j+1)}$,这与已知的低角动量谱一致。等标量磁矩被预测为$-{K_1\over 4m}{\mathbf Σ}$,其中${\mathbf Σ}$是自旋。

英文摘要:

We propose a relativistically invariant wave equation for the Skyrme soliton. It is a differential equation on the space $R^{1,3}\times S^3$ which is invariant under the Lorentz group and isospin. The internal variable valued in $SU(2)\approx S^3$ describes the orientation of the soliton. The mass of a particle of spin and isospin both equal to $j={1\over 2},{3\over 2}...$ is predicted to be $M=m\sqrt{1+K_2j(j+1)\over 1+K_1j(j+1)}$ which agrees with the known spectrum for low angular momentum. The iso-scalar magnetic moment is predicted to be $-{K_1\over 4m}{\mathbf Σ}$, where ${\mathbf Σ}$ is the spin.
