In the chiral SU(15) gauge theory presented here, the quarks and leptons are bound states ("prebaryons") of massless preons. The standard model charges of the preons imply three generations of quarks and leptons, plus some vectorlike fermions lighter than the confining scale Λ_{pre}. Under certain assumptions about the chiral dynamics, bound states of two prebaryons behave as Higgs fields. The QCD and electroweak groups may unify above Λ_{pre}, while SU(15) prevents rapid proton decay.
在本文所提出的手征SU(15)规范理论中，夸克和轻子是无质量前子的束缚态（“前重子”）。前子的标准模型电荷意味着三代夸克和轻子，再加上一些比禁闭尺度Λ_pre轻的矢量类费米子。在关于手征动力学的某些假设下，两个前重子的束缚态表现为希格斯场。QCD和电弱群可能在Λ_pre之上统一，而SU(15)可防止质子快速衰变。
