Now consider the U ( 1) gauge theory where the gauge field A μ is coupled to complex scalar field ϕ. However, quantization of a gauge theory requires us to fix a gauge. WebDec 20, 2024 · Proof : Take X = ( 1, 0, 0, ± 1), then S 11 + S 00 ± 2 S 01 = 0. It follows S 11 = − S 00 and S 01 = 0. Similarly we get S 22 = S 33 = − S 00 and S 02 = S 03 = 0. Now take X = ( 1, 1, 0, 2), then 0 = S 11 + S 22 + 2 S 00 + 2 S 12, it follows S 12 = 0. Similarly S 23 = S 13 = 0. Let λ = − S 00, the conclusion follows. the bradley on bar rescue
