Lepton flavor violation beyond the MSSM [PDF]

, 2015
Most extensions of the Standard Model lepton sector predict large lepton flavor violating rates. Given the promising experimental perspectives for lepton flavor violation in the next few years, this generic expectation might offer a powerful indirect ...

Vector unparticle enhanced black holes: exact solutions and thermodynamics [PDF]

, 2010
Tensor and scalar unparticle couplings to matter have been shown to enhance gravitational interactions and provide corrections to the Schwarzschild metric and associated black hole structure.

A perspective on Quantum Gravity Phenomenology [PDF]

, 2003
I give a brief overview of some Quantum-Gravity-Phenomenology research lines, focusing on studies of cosmic rays and gamma-ray bursts that concern the fate of Lorentz symmetry in quantum spacetime.

Vectorlike Confinement at the LHC [PDF]

, 2010
We argue for the plausibility of a broad class of vectorlike confining gauge theories at the TeV scale which interact with the Standard Model predominantly via gauge interactions.

Gravitational waves at aLIGO and vacuum stability with a scalar singlet extension of the Standard Model [PDF]

, 2017
A new gauge singlet scalar field can undergo a strongly first-order phase transition (PT) leading to gravitational waves (GW) potentially observable at aLIGO and simultaneously stabilize the electroweak vacuum.

On a Missed Mechanism of Dielectron Production in Nucleon-Nucleon Collisions

, 2010
We examine a new mechanism of $e^+e^-$ pair production in $NN$ collisions associated with the $NN$-decoupled dibaryon $d^\star_1$(1956) formation in the process $NN \to \gamma^\star d^\star_1$, where $\gamma^\star$ is the virtual photon which converts ...

Confronting dark matter with the diphoton excess from a parent resonance decay [PDF]

, 2016
A diphoton excess with an invariant mass of about 750 GeV has been recently reported by both ATLAS and CMS experiments at LHC. While the simplest interpretation requires the resonant production of a 750 GeV (pseudo)scalar, here we consider an alternative

Improved limit on quantum-spacetime modifications of Lorentz symmetry from observations of gamma-ray blazars

, 2004
In the quantum-gravity literature there has been interest in the possibility that quantum properties of spacetime might affect the energy/momentum dispersion relation.

Low-Energy Signals from Kinetic Mixing with a Warped Abelian Hidden Sector [PDF]

, 2010
We investigate the detailed phenomenology of a light Abelian hidden sector in the Randall-Sundrum framework. Relative to other works with light hidden sectors, the main new feature is a tower of hidden Kaluza-Klein vectors that kinetically mix with the ...
