Spontaneously Breaking Non-Abelian Gauge Symmetry in Non-Hermitian Field Theories
Jean Alexandre, John Ellis, Peter Millington +1
We generalise our previous formulation of gauge-invariant PT-symmetric field theories to include models with non-Abelian symmetries and discuss the extension to such models of the…
Gauge invariance and the Englert-Brout-Higgs mechanism in non-Hermitian field theories
Jean Alexandre, John Ellis, Peter Millington +1
We discuss -symmetric Abelian gauge field theories, as well as their extension to the Englert-Brout-Higgs mechanism for generating a mass for a vector boson. Gauge in…
Spontaneous symmetry breaking and the Goldstone theorem in non-Hermitian field theories
Jean Alexandre, John Ellis, Peter Millington +1
We demonstrate the extension to PT-symmetric field theories of the Goldstone theorem, confirming that the spontaneous appearance of a field vacuum expectation value via minimisatio…
Symmetries and conservation laws in non-Hermitian field theories
Jean Alexandre, Peter Millington, Dries Seynaeve
Anti-Hermitian mass terms are considered, in addition to Hermitian ones, for PT-symmetric complex-scalar and fermionic field theories. In both cases, the Lagrangian can be written…
