Annihilation Decays of Bound States at the LHC
(Springer Verlag, 2010)At the Large Hadron Collider, heavy particles may be produced in pairs close to their kinematic threshold. If these particles have strong enough attractive interactions they may form bound states. Consequently, the bound ... -
Black Holes and Quantum Gravity at the LHC
(Spinger Verlag, 2008)We argue that the highly studied black hole signatures based on thermal multiparticle final states are very unlikely and only occur in a very limited parameter regime if at all. However, we show that if the higher-dimensional ... -
Early (and Later) LHC Search Strategies for Broad Dimuon Resonances
(Springer Verlag, 2011)Resonance searches generally focus on narrow states that would produce a sharp peak rising over background. Early LHC running will, however, be sensitive primarily to broad resonances. In this paper we demonstrate that ... -
Emergent Dark Matter, Baryon, and Lepton Numbers
(Springer, 2011)We present a new mechanism for transferring a pre-existing lepton or baryon asymmetry to a dark matter asymmetry that relies on mass mixing which is dynamically induced in the early universe. Such mixing can succeed with ... -
LHC Searches for Non-Chiral Weakly Charged Multiplets
(Springer Verlag, 2011)Because the TeV-scale to be probed at the Large Hadron Collider should shed light on the naturalness, hierarchy, and dark matter problems, most searches to date have focused on new physics signatures motivated by possible ... -
Natural Neutrino Masses and Mixings from Warped Geometry
(Institute of Physics, 2009)We demonstrate that flavor symmetries in warped geometry can provide a natural explanation for large mixing angles and economically explain the distinction between the quark and lepton flavor sectors. We show how to naturally ... -
Stable Colored Particles R-SUSY Relics or Not?
(Springer, 2011)R-hadrons are only one of many possible stable colored states that the LHC might produce. All such particles would provide a spectacular, if somewhat unusual, signal at ATLAS and CMS. Produced in large numbers and leaving ... -
Two-Higgs Models for Large \(\tan \beta\) and Heavy Second Higgs
(Institute of Physics, 2008)We study two-Higgs models for large \(\tan \beta\) and relatively large second Higgs mass. In this limit the second heavy Higgs should have small vev and therefore couples only weakly to two gauge bosons. Furthermore, the ...
