Implications of a Electroweak Triplet Scalar Leptoquark on the Ultra-High Energy Neutrino Events at IceCube
Nicolas Mileo, Alejandro de la Puente, Alejandro Szynkman
We study the production of scalar leptoquarks at IceCube, in particular, a particle transforming as a triplet under the weak interaction. The existence of electroweak-triplet scala…
Breakdown of Effective Field Theory for a Gluon Initiated Resonance
Alejandro de la Puente, Daniel Stolarski
Gauge invariance dictates that a resonance produced from initial state gluons must be produced through a non-renormalizable operator or a loop process. Should such a resonance be d…
The Dilaton-like Higgs boson with scalar singlet dark matter
Robyn Campbell, Stephen Godfrey, Alejandro de la Puente
We study a model with a Higgs-like dilaton and a Standard Model gauge-singlet scalar dark matter candidate. We begin by updating the status of identifying the observed 125 GeV Higg…
Compressing the Inert Doublet Model
Nikita Blinov, Jonathan Kozaczuk, David E. Morrissey +1
The Inert Doublet Model relies on a discrete symmetry to prevent couplings of the new scalars to Standard Model fermions. This stabilizes the lightest inert state, which can then c…
Electroweak Vacuum Stability and the Seesaw Mechanism Revisited
John Ng, Alejandro de la Puente
We study the electroweak vacuum stability in Type I seesaw models for 3 generations of neutrinos in scenarios where the right-handed neutrinos have explicit bare mass terms in the…
Search for Heavy Right-Handed Neutrinos at the LHC and Beyond in the Same-Sign Same-Flavor Leptons Final State
John N. Ng, Alejandro de la Puente, Bob Wei-Ping Pan
In this study we explore the LHC's Run II potential to the discovery of heavy Majorana neutrinos, with luminosities between and fb in the fin…
Long-lived Colored Scalars at the LHC
Alejandro de la Puente, Alejandro Szynkman
We study the collider signatures of a long-lived massive colored scalar transforming trivially under the weak interaction and decaying within the inner sections of a detector such…
Vector-like quarks with a scalar triplet
Estefania Coluccio Leskow, Travis Martin, Alejandro de la Puente
We study a minimal extension to the Standard Model with an additional real scalar triplet, , and a single vector-like quark, . This class of models appear naturally in extens…
Probing Radiative Neutrino Mass Generation through Monotop Production
John N. Ng, Alejandro de la Puente
We present a generalization of a model where the right-handed up-type quarks serve as messengers for neutrino mass generation and as a portal for dark matter. Within this framework…
A Singlet Extension of the MSSM with a Dark Matter Portal
Alejandro de La Puente, Walter Tangarife
The minimal extension of the MSSM (NMSSM) has been widely studied in the search for a natural solution to the problem. In this work, we consider a variation of the NMSSM where…
Top Quark as a Dark Portal and Neutrino Mass Generation
John N. Ng, Alejandro de la Puente
We present a new model for radiatively generating Majorana active neutrino masses while incorporating a viable dark matter candidate. This is possible by extending the Standard Mod…
Darkening the Little Higgs
Travis A. W. Martin, Alejandro de la Puente
We present a novel new method for incorporating dark matter into little Higgs models in a way that can be applied to many existing models without introducing T-parity, while simult…
Manifestations of Warped Extra Dimension in Rare Charm Decays and Asymmetries
Ayan Paul, Alejandro de la Puente, Ikaros I. Bigi
We study the effects of models with a warped extra dimension on rare charm decays. While the new degrees of freedom in these models are bounded above a few TeV, they can leave sign…
LHC Signals of Non-Custodial Warped 5D Models
Jorge de Blas, Antonio Delgado, Bryan Ostdiek +1
We study the implications at the LHC for a recent class of non-custodial warped extra-dimensional models where the AdS_5 metric is modified near the infrared brane. Such models all…
The Forward-Backward Top Asymmetry in a Singlet extension of the MSSM
Alejandro de la Puente
The CDF and D0 collaborations have recently reported a large forward-backward asymmetry in the ttbar system which deviates from the next to-leading order QCD standard model predict…
Solving the Hierarchy Problem with a Light Singlet and Supersymmetric Mass Terms
Antonio Delgado, Christopher Kolda, Alejandro de la Puente
A generalization of the Next-to-Minimal Supersymmetric Model (NMSSM) is studied in which an explicit μ-term as well as a small supersymmetric mass term for the singlet superfield a…
Signals of CP Violation Beyond the MSSM in Higgs and Flavor Physics
Wolfgang Altmannshofer, Marcela Carena, Stefania Gori +1
We study an extension of the Higgs sector of the Minimal Supersymmetric Standard Model (MSSM), considering the effects of new degrees of freedom at the TeV scale, and allowing for…
Performance test of wavelength-shifting acrylic plastic Cherenkov detector
B. Beckford, A. de la Puente, Y. Fuji +10
The collection efficiency for Cherenkov light incident on a wavelength shifting plate (WLS) has been determined during a beam test at the Proton Synchrotron facility located in the…
A Gauge-Mediated Embedding of the S-MSSM
Antonio Delgado, Christopher Kolda, J. Pocahontas Olson +1
We embed the S-MSSM -- a singlet extension of the minimal supersymmetric standard model with an explicit mu-term and supersymmetric mass term -- in a gauge-mediated supersymmetry b…
The SUSY Higgs Mass: the Singlet Saves the Day
Antonio Delgado, Christopher Kolda, J. Pocahontas Olson +1
We present a generalization of the Next-to-Minimal Supersymmetric Standard Model (NMSSM), with an explicit mu-term and a supersymmetric mass for the singlet superfield, as a route…
New fits to the reaction
Alejandro de la Puente, Oren V. Maxwell, Brian A. Raue
The reaction has been investigated over the center-of-momentum energy, , range from threshold up to 2.2 GeV in a tree-level effective Lagrangian model that incorpor…
