Bulk renormalization and particle spectrum in codimension-two brane worlds
Journal of Physics, Conference Series
We study the Casimir energy due to bulk loops of matter fields in codimension-two brane worlds and discuss how effective field theory methods allow us to use this result to renormalize the bulk and brane operators. In the calculation we explicitly sum over the Kaluza-Klein (KK) states with a new convenient method, which is based on a combined use of zeta function and dimensional regularization. Among the general class of models we consider we include a supersymmetric example, 6D gauged chiraldoi:10.1088/1742-6596/437/1/012004 fatcat:cm7itmqswzd5xeanv6f3mxrfai
