SU(2)规范玻色子的动力学对称破缺

Dynamical Symmetry Breaking by SU(2) Gauge Bosons

F. J. Himpsel

摘要:

这项工作探讨了在杨-米尔斯理论中通过内禀规范玻色子获得质量间隙的可能性,而不需要调用单独的希格斯玻色子玻色子或费米子-反费米子对。相反,自旋和同位旋单重态的规范玻色子对形成一对复合希格斯玻色子,可以被视为杨-米尔斯规范理论中最简单的胶球。二次和四次规范玻色子的自相互作用形成了一个势,导致规范玻色子振幅的有限期望值。横向偏振确保了在对所有可能的偏振矢量进行平均之后真空的洛伦兹不变性。但是标量对乘积呈现出有限的真空期望值,这动态地破坏了规范对称性。与标准希格斯势的相容性决定了二次和四次耦合常数。

英文摘要:

This work explores the possibility of obtaining a mass gap in Yang-Mills theories via the intrinsic gauge bosons, without invoking a separate Higgs boson or fermion-antifermion pairs. Instead, pairs of gauge bosons in the spin and isospin singlet state form a pair of composite Higgs bosons which can be viewed as the simplest possible glueball of Yang-Mills gauge theories. Quadratic and quartic gauge boson self-interactions form a potential that leads to a finite expectation value of the gauge boson amplitude. Transverse polarization ensures Lorentz invariance of the vacuum after averaging over all possible polarization vectors. But the scalar pair products exhibit a finite vacuum expectation value which breaks the gauge symmetry dynamically. Compatibility with the standard Higgs potential determines the quadratic and quartic coupling constants.
