摘要
We review constraints from quark and lepton flavor violation on extra dimensional models with warped geometry, both in the minimal and the custodial model. For both scenarios, Kaluza-Klein (KK) masses that are large enough to suppress constraints from electroweak precision tests (EWPT) also sufficiently suppress all quark flavor and CP violation, with the exception of CP violation in K (K) over bar mixing and (to a lesser extend) in D (D) over bar mixing. In the lepton sector the minimal scenario leads to excessively large contributions to mu -> e gamma transitions, requiring KK masses of at least 20 TeV or larger.
