Finding the Higgs boson through supersymmetry (2009)
De Campos, F., Eboli, O.J.P., Magro, M.B., Restrepo, Diego, Valle, José W. F.
The study of displaced vertices containing two b-jets may provide a double discovery at the Large Hadron Collider (LHC): we show how it may not only reveal evidence for supersymmetry, but also...
Decaying neutralino dark matter in anomalous $U(1)_H$ models (2009)
Sierra, D. Aristizabal, Restrepo, Diego, Zapata, Oscar
In supersymmetric models extended with an anomalous $U(1)_H$ different R-parity violating couplings can yield an unstable neutralino. We show that in this context astrophysical and cosmological...
Molecular Tuning of Odorant Receptors and Its Implication for Odor Signal Processing (2009)
Reisert, Johannes, Restrepo, Diego
The discovery of the odorant receptor (OR) family by Buck and Axel in 1991 provided a quantum jump in our understanding of olfactory function. However, the study of the responsiveness of ORs to odor...
TRPM5-expressing microvillous cells in the main olfactory epithelium (2008)
Lin, Weihong, Ezekwe, Ejiofor AD, Zhao, Zhen, Liman, Emily R, Restrepo, Diego
Abstract Background The main olfactory epithelium (MOE) in the nasal cavity detects a variety of air borne molecules that provide information regarding the presence of food, predators and other...
Profound Context-Dependent Plasticity of Mitral Cell Responses in Olfactory Bulb (2008)
Wilder Doucette, Diego Restrepo
On the basis of its primary circuit it has been postulated that the olfactory bulb (OB) is analogous to the retina in mammals. In retina, repeated exposure to the same visual stimulus results in a...
BDNF Promoter-Mediated {beta}-Galactosidase Expression in the Olfactory Epithelium and Bulb (2008)
Clevenger, Amy C., Salcedo, Ernesto, Jones, Kevin R., Restrepo, Diego
The neurotrophin brain-derived neurotrophic factor (BDNF) has been implicated in the generation and differentiation of new olfactory sensory neurons (OSNs) and in the regulation of branching of OSN...
Gating effects along mitral cell lateral dendrites (2007)

Leptonic Charged Higgs Decays in the Zee Model (2006)
Sierra, D. Aristizabal, Restrepo, Diego
We consider the version of the Zee model where both Higgs doublets couple to leptons. Within this framework we study charged Higgs decays. We focus on a model with minimal number of parameters...
Clevenger, Amy C., Restrepo, Diego
Threshold is defined as the stimulus intensity necessary for a subject to reach a specified percent correct on a detection test. MLPEST (maximum likelihood parameter estimation by sequential testing)...
Ernesto Salcedo, Chunbo Zhang, Eugene Kronberg, Diego Restrepo
Odor quality is thought to be encoded by the activation of partially overlapping subsets of glomeruli in the olfactory bulb (odor maps). Mouse genetic studies have demonstrated that olfactory sensory...

Bounds on the tau and muon neutrino vector and axial vector charge radius (2002)
Hirsch, Martin, Nardi, Enrico, Restrepo, Diego
A Majorana neutrino is characterized by just one flavor diagonal electromagnetic form factor: the anapole moment, that in the static limit corresponds to the axial vector charge radius . Experimental...
Phenomenology of Bilinear Broken R-parity (2001)
The straightforward supersymmetrization of the Standard Model (SM) results in a phenomenologically inconsistent theory in which Baryon number ($B$) and Lepton number ($L$) are violated by dimension 4...
Broken R-parity, stop decays, and neutrino physics (2001)
Restrepo, Diego, Porod, Werner, Valle, Jose W. F.
We discuss the phenomenology of the lightest stop in models where R-parity is broken by bilinear superpotential terms. In this class of models we consider scenarios where the R-parity breaking...
Lin, Weihong, Margolskee, Robert, Donnert, Gerald, Hell, Stefan W., Restrepo, Diego
Olfactory sensory neurons (OSNs) in the main olfactory epithelium respond to environmental odorants. Recent studies reveal that these OSNs also respond to semiochemicals such as pheromones and that...
BDNF Promoter–Mediated β-Galactosidase Expression in the Olfactory Epithelium and Bulb
Clevenger, Amy C., Salcedo, Ernesto, Jones, Kevin R., Restrepo, Diego

Adrenergic modulation of olfactory bulb circuitry affects odor discrimination
Doucette, Wilder, Milder, Julie, Restrepo, Diego
A rodent’s survival depends upon its ability to perceive odor cues necessary to guide mate selection, sexual behavior, foraging, territorial formation, and predator avoidance. Arguably, the need to...
