Ward identity and electrical conductivity in hot QED
We study the Ward identity for the effective photon-electron vertex summing the ladder diagrams contributing to the electrical conductivity in hot QED at leading logarithmic order. It is shown that the Ward identity requires the inclusion of a new diagram in the integral equation for the vertex that has not been considered before. The real part of this diagram is subleading and therefore the fi...

We study the cancellations among Feynman diagrams that implement the Ward and SlavnovTaylor identities corresponding to the conserved supersymmetry current in supersymmetric quantum field theories. In particular, we show that the Faddeev-Popov ghosts of gaugeand supersymmetries never decouple from the physical fields, even for abelian gauge groups. The supersymmetric Slavnov-Taylor identities p...
متن کاملThree point SUSY Ward identities without Ghosts
We utilise a non-local gauge transform which renders the entire action of SUSY QED invariant and respects the SUSY algebra modulo the gauge-fixing condition, to derive twoand three-point ghost-free SUSY Ward identities in SUSY QED. We use the cluster decomposition principle to find the Green’s function Ward identities and then takes linear combinations of the latter to derive identities for the...
متن کاملThe Nielsen Identities for the Two - Point Functions of QED and QCD
We consider the Nielsen identities for the two-point functions of full QCD and QED in the class of Lorentz gauges. For pedagogical reasons the identities are first derived in QED to demonstrate the gauge independence of the photon self-energy, and of the electron mass shell. In QCD we derive the general identity and hence the identities for the quark, gluon and ghost propagators. The explicit c...

Comment on " Radiative decays, nonet symmetry and SU(3) breaking ". Abstract We comment on the paper We show that the decay φ → π 0 γ is absent in model of the nonet symmetry and SU(3) breaking suggested by authors.
