urn:hdl:2445/145713 Wilson loops in antisymmetric representations from localization in supersymmetric gauge theories Russo, J. G. (Jorge Guillermo) Zarembo, Konstantin Simetria (Física) Teoria de camps (Física) Symmetry (Physics) Field theory (Physics) Large-N phase transitions occurring in massive N=2 theories can be probed by Wilson loops in large antisymmetric representations. The logarithm of the Wilson loop is effectively described by the free energy of a Fermi distribution and exhibits second-order phase transitions (discontinuities in the second derivatives) as the size of representation varies. We illustrate the general features of antisymmetric Wilson loops on a number of examples where the phase transitions are known to occur: N=2 SQCD with various mass arrangements and N=2∗ theory. As a byproduct, we solve planar N=2 SQCD with three independent mass parameters. This model has two effective mass scales and undergoes two phase transitions. 2019-11-29T15:05:36Z 2019-12-31T06:10:20Z 2018 2019-11-29T15:05:38Z info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Versió postprint del document publicat a: https://doi.org/10.1142/S0129055X18400147 Reviews in Mathematical Physics, 2018, vol. 30, num. 7 https://doi.org/10.1142/S0129055X18400147 info:eu-repo/grantAgreement/EC/FP7/341222/EU//INTEGRAL (c) World Scientific Publishing, 2018 info:eu-repo/semantics/openAccess World Scientific Publishing Articles publicats en revistes (Física Quàntica i Astrofísica)
