Existence and profile covariance of the modified QED scattering matrix and interacting fields
Let η\etaη be a profile, let v\mathrm{v}v be a four-velocity, let C∈{Fμν,jμ}C\in\{F^{\mu\nu},j^\mu\}C∈{Fμν,jμ} be an observable field, and let Ψ,Ψ′∈D2\Psi,\Psi'\in\mathcal{D}_2Ψ,Ψ′∈D2. The BRST charge is denote…
