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 ...

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.

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.

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 ...

, 2010 There is a non-trivial four-derivative extension of the gravitational spectrum that is free of ghosts and phenomenologically viable. It is the so called $R^2$-gravity since it is defined by the only addition of a term proportional to the square of the ...

Phenomenology of TeV-scale scalar Leptoquarks in the EFT
, 2019 We examine new aspects of leptoquark (LQ) phenomenology using effective field theory (EFT). We construct a complete set of leading effective operators involving SU(2) singlets scalar LQ and the SM fields up to dimension six.

TASI 2009 Lectures: Searching for Unexpected Physics at the LHC [PDF]
, 2010 These TASI lectures consider low mass hidden sectors from Hidden Valleys, Quirks and Unparticles. We show how each corresponds to a different limit of the same class of models: hidden sectors with non-abelian gauge groups with mass gaps well below a TeV ...
