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 0129-055X https://hdl.handle.net/2445/145713 684738 eng 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 19 p. application/pdf World Scientific Publishing Articles publicats en revistes (Física Quàntica i Astrofísica)
