Résumé |
I will discuss a method to compute the one-point functions of chiral primary
operators in 4d N=2 SCFTs with ½ BPS boundary conditions. A SUSY identity relates
these correlators to derivatives of the hemisphere partition function, adapting to
the boundary case the known method to compute chiral/antichiral two-point
functions. This requires to take appropriate care of certain boundary terms in the
Ward identities. I will then show the localization formulas that can be used to
derive exact results for these one-point functions. As an explicit example, I will
focus on the case of super Maxwell theory coupled to a 3d N=2 SCFT on the
boundary.
