Three point SUSY Ward identities without Ghosts
نویسنده
چکیده
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 proper functions.

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.

متن کاملSUSY Ward identities, Superamplitudes, and Counterterms
Ward identities of SUSY and R-symmetry relate n-point amplitudes in supersymmetric theories. We review recent work in which these Ward identities are solved in N = 4 SYM and N = 8 supergravity. The solution, valid at both tree and loop level, expresses any NMHV superamplitude in terms of a basis of ordinary amplitudes. Basis amplitudes are classified by semi-standard tableaux of rectangular N -...
متن کاملWard Identities for N = 2 Rigid and Local Supersymmetry in Euclidean Space
We construct and check by explicit Feynman diagram calculations the BRST Ward identities for N = 2 rigid super Yang-Mills theory and N = 2 extended supergravity in four-dimensional Euclidean space without auxiliary fields. We use the Batalin-Vilkovisky formalism. In the supergravity case we need one new contractible pair of complex spinor fields to obtain the usual gauge-fixing term and corresp...
متن کاملThe supersymmetric Ward identities on the lattice DESY - Münster - Roma Collaboration
Supersymmetric (SUSY) Ward identities are considered for the N=1 SU(2) SUSY Yang Mills theory discretized on the lattice with Wilson fermions (glu-inos). They are used in order to compute non-perturbatively a subtracted gluino mass and the mixing coefficient of the SUSY current. The computations were performed at gauge coupling β = 2.3 and hopping parameter κ = 0.1925, 0.194, 0.1955 using the t...
