Unstable instantons in A-model localization
Abstract We apply localization techniques to A-twisted N $$ \mathcal{N} $$ = (2) theories of vector multiplets on S 2. We derive formulae for A-model partition functions and correlators as integrals along a real contour, as opposed to a complex one. Using the correlator formula, we successfully reco...

| description | Abstract We apply localization techniques to A-twisted N $$ \mathcal{N} $$ = (2) theories of vector multiplets on S 2. We derive formulae for A-model partition functions and correlators as integrals along a real contour, as opposed to a complex one. Using the correlator formula, we successfully recover the unstable instanton partition function of pure two-dimensional Yang-Mills theory from the vacuum expectation value of an A-model operator. |
