Non-universal corrections to the tension ratios in softly broken N=2 SU(N) gauge theory
Roberto Auzzi, Kenichi Konishi
TL;DR
This paper extends the calculation of vortex tension ratios in softly broken N=2 SU(N) gauge theory to second order, revealing corrections that challenge the universality of the sine formula.
Contribution
It provides a second-order correction analysis of vortex tension ratios, demonstrating that these ratios are not universally given by the sine formula.
Findings
Corrections to tension ratios violate the sine formula.
Tension ratios are not universal quantities.
Second-order effects are significant in the analysis.
Abstract
Calculation by Douglas and Shenker of the tension ratios for vortices of different N-alities in the softly broken N=2 supersymmetric SU(N) Yang-Mills theory, is carried to the second order in the adjoint multiplet mass m. Corrections to the ratios violating the well-known sine formula are found, showing that it is not a universal quantity.
