$C_T$ for monodromy defects of fields on odd dimensional spheres for higher derivative propagation
Abstract
The central charge is computed for scalar and Dirac fields propagating according to GJMS-type kinetic operators acting on odd -dimensional spheres in the presence of a spherical monodromy. The relation of to the derivatives of the free energy on the conically deformed sphere via the Perlmutter factor leads to a numerical quadrature. The variation of with the monodromy flux, , displays sign changes, exactly as in even dimensions. Closed forms for are derived when equals 0 or 1/2 with the derivative order either even or odd and shown to agree with existing, even expressions. The infinite limits are also derived in these special cases.
