Fermionic Dark Matter in a Scotogenic Model with a Complex Scalar Singlet
Gustavo Ardila-Tafurth, Andrés Flórez, Victor Martín-Lozano +1
We study the phenomenology of the complex scoto-singlet model, an extension of the scotogenic framework that simultaneously accounts for radiative neutrino masses and fermionic dar…
Discovery and exclusion prospects for staus produced by heavy Higgs bosons decays at the LHC
Ernesto Arganda, Víctor Martín-Lozano, Anibal D. Medina +1
In a previous work we developed a search strategy for staus produced by the decay of the heavy CP-even Higgs boson within the context of the large regime of the minimal…
Confronting the neutralino and chargino sector of the NMSSM to the multi-lepton searches at the LHC
Florian Domingo, Jong Soo Kim, Victor Martin-Lozano +2
We test the impact of the ATLAS and CMS multi-lepton searches performed at the LHC with 8 as well as 13 TeV center-of-mass energy (using only the pre-2018 results) on the chargino…
Potential discovery of staus through heavy Higgs boson decays at the LHC
Ernesto Arganda, Victor Martin-Lozano, Anibal D. Medina +1
In this work we present a new search strategy for the discovery of staus at the LHC in the context of the minimal supersymmetric standard model. The search profits from the large s…
The Constrained NMSSM with right-handed neutrinos
David G. Cerdeno, Valentina De Romeri, Victor Martin-Lozano +2
In this article, we study the renormalization group equations of the Next-to-Minimal Supersymmetric Standard Model, and investigate universality conditions on the soft supersymmetr…
Confronting SUSY models with LHC data via electroweakino production
Chiara Arina, Mikael Chala, Victor Martin-Lozano +1
We investigate multi-lepton signals produced by ElectroWeakino (EWino) decays in the MSSM and the TMSSM scenarios with sfermions, gluinos and non Standard Model Higgses at the TeV…
Confronting dark matter with the diphoton excess from a parent resonance decay
Valentina De Romeri, Jong Soo Kim, Victor Martin-Lozano +2
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 resona…
A Megaxion at 750 GeV as a First Hint of Low Scale String Theory
Luis E. Ibanez, Victor Martin-Lozano
Low scale string models naturally have axion-like pseudoscalars which couple directly to gluons and photons (but not s) at tree level. We show how they typically get tree level…
Dark Matter phenomenology of intersecting D6-branes with a Stueckelberg portal
Victor Martin-Lozano
We discuss the possibility that a Stueckelberg portal connects both Standard Model and Dark Matter sectors. The particle responsible of this portal is the lightest Z' boson that in…
Resonant Higgs boson pair production in the decay channel
Victor Martin-Lozano, Jesus M. Moreno, Chan Beom Park
Adding a scalar singlet provides one of the simplest extensions of the Standard Model. In this work we briefly review the latest constraints on the mass and mixing of the new Higgs…
Dark Matter versus h into gamma gamma and h into gamma Z with supersymmetric triplets
Chiara Arina, Victor Martin-Lozano, Germano Nardini
The Triplet extension of the MSSM (TMSSM) alleviates the little hierarchy problem and provides a significant enhancement of the loop-induced diphoton rate of the lightest CP-even H…
Displaced vertices and long-lived charged particles in the NMSSM with right-handed sneutrinos
David G. Cerdeno, Victor Martin-Lozano, Osamu Seto
We study LHC signatures of displaced vertices and long-lived charged particles within the context of the Next-to-Minimal Supersymmetric Standard Model with right-handed (RH) sneutr…
