Gauge dependence of the one-loop divergences in 6D, N=(1,0) abelian theory

Abstract: We study the gauge dependence of the one-loop effective action for the abelian 6D, N = (1, 0) supersymmetric gauge theory formulated in harmonic superspace. We introduce the superfield ξ-gauge, construct the corresponding gauge superfield propagator, and calculate the one-loop two-and three-point Green functions with two external hypermultiplet legs. We demonstrate that in the general ξ-gauge the two-point Green function of the hypermultiplet is divergent, as opposed to the Feynman gauge ξ = 1. The three-point… Show more

“…Like in our previous publications, we deal with the six-dimensional N = (1, 1) supersymmetric gauge theory formulated in N = (1, 0) harmonic superspace [17], [18], [19] (for the harmonic superspace approach, see [20], [21]). The theory is quantized in the framework of the harmonic superfield background method which was originally developed for 4D, N = 2 SYM theories in [22], [23], [24] 3 and then generalized to 6D, N = (1, 0) gauge theories in [8], [25], [26], [27].…”
