Localized tadpoles and anomalies in 6D orbifolds

초록

In this talk, we review the instability due to radiatively induced FI tadpoles in N = 2 supersymmetric gauge theories on orbifolds in six dimensions. Even with localized FI tadpoles, we have unbroken supersymmetry at the expense of having the spontaneous localization of bulk zero mode. We find the non-decoupling of massive modes, unlike the 5D case. We also comment on local-anomaly cancellation.
