标题： Charge fractionization in N=2 supersymmetric QCD

摘要： 结果显示，在$N=2$超对称QCD的超对称代数中心荷中出现的物理“夸克数”电荷可以取无理数值，并且非平凡地依赖于希格斯期望值。 这给出了当“电”和“磁”变量$a_D$和$a$绕过奇点时所经历的常数位移的物理解释，并表明该模型中的对偶性确实是真正的电-磁-夸克数对偶性。 还包括在微观理论中直接计算单色矩阵。 显示英文摘要

摘要： It is shown that the physical ``quark number'' charges which appear in the central charge of the supersymmetry algebra of $N=2$ supersymmetric QCD can take irrational values and depend non trivially on the Higgs expectation value. This gives a physical interpretation of the constant shifts which the ``electric'' and ``magnetic'' variables $a_D$ and $a$ undergo when encircling a singularity, and show that duality in this model is trully an electric-magnetic-quark number duality. Also included is a computation of the monodromy matrices directly in the microscopic theory.
