Consequences of symmetry breaking on conformal defect data |
|
Résumé |
Conformal defects break part of the symmetry of a bulk CFT. The broken Ward
identities lead to very general sum rules on the defect CFT data as well as on the
data of bulk operators in the presence of a defect. We call these sum rules
"defect soft theorems", and they hold generally for defects which break conformal
symmetry, flavor symmetry, or supersymmetry. In this talk I will focus on line
defects for which we can rewrite the constraints in dispersive sum rule form, and
show how the defect soft theorems impose constraints on the defect spectrum and
OPE coefficients. |
