轻子、夸克或两者都是费米子和标量的高度相对论束缚态?

Could Leptons, Quarks or both be Highly Relativistic Bound States of Minimally Interacting Fermion and Scalar?

G. B. Mainland

摘要:

讨论了轻子、夸克或两者都是自旋为0和自旋为1/2的组分的高度相对论束缚态的可能性。通常,Bethe-Salpeter方程的强约束解仅在耦合常数等于或大于1时存在。对于本文所讨论的束缚态系统,存在两类边界条件,可以得到耦合常数为电磁精细结构常数量级的强束缚解.在这两种情况下,束缚态的自旋都必须是1/2,这就为没有高自旋轻子和夸克提供了一个可能的解释。

英文摘要:

The possibility that leptons, quarks or both might be highly relativistic bound states of a spin-0 and spin-1/2 constituent bound by minimal electrodynamics is discussed. Typically, strongly bound solutions of the Bethe-Salpeter equation exist only when the coupling constant is on the order of or greater than unity. For the bound-state system discussed here, there exist two classes of boundary conditions that could yield strongly bound solutions with coupling constants on the order of the electromagnetic fine structure constant. In both classes the bound state must have spin one half, thus providing a possible explanation for the absence of higher-spin leptons and quarks.
