Sequestering CP Violation and GIM-Violation with Warped Extra Dimensions
We propose a model of spontaneous CP violation to address the strong CP problem in warped extra dimensions that relies on sequestering flavor and CP violation. We assume that brane-localized Higgs Yukawa interactions respect a U(3) flavor symmetry that is broken only by bulk fermion mass and Yukawa terms. All CP violation arises from the vev of a CP-odd scalar field localized in the bulk. To su...
متن کاملGeometric CP violation with extra dimensions.
We discuss how CP symmetry can be broken geometrically through orbifold projections in hidden extra dimensions in the context of brane-bulk models for particle unifications. The CP violation arises from a crash between the geometry of the compactification and the original higher dimensional CP definition. We present toy models to illustrate the idea and suggest ways to incorporate it into more ...
متن کاملLorentz Violation in Warped Extra Dimensions ∗ †
Higher dimensional theories which address some of the problematic issues of the Standard Model(SM) naturally involve some form of D = 4 + n-dimensional Lorentz invariance violation (LIV). In such models the fundamental physics which leads to, e.g., field localization, orbifolding, the existence of brane terms and the compactification process all can introduce LIV in the higher dimensional theor...
متن کاملSpontaneous CP Violation in Large Extra Dimensions
We show that in the context of large extra dimensions enough CP violation can be obtained from the spontaneous breaking in a simple non-SUSY model, which is usually considered not to cause the spontaneous CP violation. We estimate ǫK in our scenario to be of order 10 −3 consistent with the experimental value. We also propose a modification to the see-saw mechanism and axion scenario to match wi...
متن کاملFlavor Violation in Warped Extra Dimensions and CP Asymmetries in B Decays
We show that CP asymmetries in b → s hadronic decays are potentially affected by the presence of massive color-octet particles strongly coupled to the third generation quarks. Theories with warped extra dimensions provide natural candidates in the Kaluza-Klein excitations of gluons in scenarios where flavor-breaking by bulk fermion masses results in the localization of fermion wave-functions. T...
