Review of asymmetric dark matter
Asymmetric dark matter models are based on the hypothesis that the present-day abundance of dark matter has the same origin as the abundance of ordinary or visible matter: an asymmetry in the numberExpand
Reconsidering the one leptoquark solution: flavor anomalies and neutrino mass
A bstractWe reconsider a model introducing a scalar leptoquark ϕ ∼ (3,1, −1/3) to explain recent deviations from the standard model in semileptonic B decays. The leptoquark can accommodate theExpand
The AGASA and SUGAR Anisotropies and TeV Gamma Rays from the Galactic Center: A Possible Signature of Extremely High Energy Neutrons
Recent analysis of data sets from two extensive air shower cosmic-ray detectors shows tantalizing evidence of an anisotropic overabundance of cosmic rays toward the Galactic center region that "turnsExpand
Poincaré protection for a natural electroweak scale
We discuss a class of technically-natural UV extensions of the Standard Model in which the electroweak scale is shielded from large radiative corrections from heavy UV physics due to an enhancedExpand
Phenomenology of a very light scalar (100 MeV < mh< 10 GeV) mixing with the SM Higgs
A bstractIn this paper we investigate the phenomenology of a very light scalar, h, with mass 100 MeV < mh  < 10 GeV, mixing with the SM Higgs. As a benchmark model we take the real singlet scalarExpand
A model with fundamental improper spacetime symmetries
Abstract It is shown how the standard model can be extended so that both the lagrangian and the vacuum are invariant under appropriately defined space- and time-inversion transformations. This meansExpand
Solution to the hierarchy problem from an almost decoupled hidden sector within a classically scale invariant theory
If scale invariance is a classical symmetry then both the Planck scale and the weak scale should emerge as quantum effects. We show that this can be realized in simple scale invariant theories with aExpand
Testing radiative neutrino mass models at the LHC
A bstractThe Large Hadron Collider provides us new opportunities to search for the origin of neutrino mass. Beyond the minimal see-saw models a plethora of models exist which realise neutrino mass atExpand
A_4 flavour symmetry breaking scheme for understanding quark and neutrino mixing angles
We propose a spontaneous A_4 flavour symmetry breaking scheme to understand the observed pattern of quark and neutrino mixing. The fermion mass eigenvalues are arbitrary, but the mixing angles areExpand
Visible and dark matter from a first-order phase transition in a baryon-symmetric universe
The similar cosmological abundances observed for visible and dark matter suggest a common origin for both. By viewing the dark matter density as a dark-sector asymmetry, mirroring the situation inExpand
