Flavour from accidental symmetries
We consider a new approach to fermion masses and mixings in which no special “horizontal” dynamics is invoked to account for the hierarchical pattern of charged fermion masses and for the peculiar features of neutrino masses. The hierarchy follows from the vertical, family-independent structure of the model, in particular from the breaking pattern of the Pati-Salam group. The lightness of the f...
متن کاملSymmetries of supergravity black holes
We investigate Killing tensors for various black hole solutions of supergravity theories. Rotating black holes of an ungauged theory, toroidally compactified heterotic supergravity, with NUT parameters and two U(1) gauge fields are constructed. If both charges are set equal, then the solutions simplify, and then there are concise expressions for rank-2 conformal Killing– Stäckel tensors. These ...
متن کاملOn duality symmetries of supergravity invariants
The role of duality symmetries in the construction of counterterms for maximal supergravity theories is discussed in a field-theoretic context from different points of view. These are: dimensional reduction, the question of whether appropriate superspace measures exist and information about non-linear invariants that can be gleaned from linearised ones. The former allows us to prove that F-term...
متن کاملAccidental Symmetries and N=1 Duality in Supersymmetric Gauge Theory
We note that the accidental symmetries which are present in some examples of duality imply the existence of continuously infinite sets of theories with the same infrared behavior. These sets interpolate between theories of different flavors and colors; the change in color and flavor is compensated by interactions (often non-perturbative) induced by operators in the superpotential. As an example...
متن کاملOn Hidden Symmetries in d = 11 Supergravity and Beyond 1
This talk is about hidden symmetries in eleven dimensions, but it is equally a tribute to a scientist and friend, who is eminently visible in four space-time dimensions: François Englert, in whose honor this meeting is being held. Therefore, before entering dans le vif du sujet I would like to express my gratitude for having had the opportunity and privilege to learn from him and to work with h...
