Boundaries in Free Higher Derivative Conformal Field Theories
I will discuss free higher derivative theories of scalars and Dirac fermions in the presence of a boundary in general dimension. We established a method for finding consistent conformal boundary conditions in these theories by removing certain boundary primaries from the spectrum. In particular, a rich set of renormalization group flows between various conformal boundary conditions is revealed, triggered by deformations quadratic in the boundary primaries. I will also discuss some quantities which characterize the boundary theory such as the hemisphere free energy and the two-point function of the displacement operator.
