Primordial Dirac Leptogenesis
Aqeel Ahmed, Juan P. Garcés, Manfred Lindner
We present a novel realization of Dirac leptogenesis based on the post-inflationary reheating phase of the early universe. An asymmetry generated within the scalar sector via CP-vi…
Radiative Symmetry Breaking with a Scale Invariant Seesaw
Aqeel Ahmed, Juan P. Garcés, Manfred Lindner
We study a scale invariant inverse seesaw model that radiatively generates the electroweak scale, the Standard Model (SM) neutrino masses, and stabilizes the electroweak vacuum. Pr…
Dynamical origin of flavor hierarchies in a warped extra dimension
Aqeel Ahmed, Adrian Carmona, Javier Castellano Ruiz +2
Extensions of the Standard Model featuring a warped extra dimension compactified on an orbifold, in which the fermions and gauge bosons live in the bulk of the f…
Heavy Higgs of the Twin Higgs Models
Aqeel Ahmed
Twin Higgs models are the prime illustration of neutral naturalness, where the new particles of the twin sector, gauge singlets of the Standard Model (SM), ameliorate the little hi…
Clockwork Goldstone Bosons
Aqeel Ahmed, Barry M. Dillon
The clockwork mechanism has recently been proposed as a natural way to generate hierarchies among parameters in quantum field theories. The mechanism is characterized by a very spe…
Implications of the absence of high-mass radion signals
Aqeel Ahmed, Barry M. Dillon, Bohdan Grzadkowski +2
Given the disappearance of the 750 GeV di-photon LHC signal and the absence of signals at high mass in this and other channels, significant constraints on the mixed Higgs-radion of…
