Fermionic Dark Matter in a Scotogenic Model with a Complex Scalar Singlet
Gustavo Ardila-Tafurth, Andrés Flórez, Andrés Flórez +3
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…
Collider Probes of Dark Energy Microphysics
Chaitanya Bashyam, Alfredo Gurrola, Andres Florez +1
The physical origin of dark energy remains one of the most profound open questions in modern physics. Although cosmological observations tightly constrain the equation of state par…
Heavy Neutrinos across the Electroweak-to-Multi-TeV Frontier via Novel ML-Enhanced Probes
Yin-Fa Shen, Alfredo Gurrola, Francesco Romeo +2
We propose a new strategy to probe heavy neutrinos with non-universal fermion couplings at the Large Hadron Collider (LHC) using a novel production mechanism and machine-learning a…
Feasibility to probe the dynamical scotogenic model at the LHC
Gustavo Ardila-Tafurth, Andrés Flórez, Cristian RodrÃguez +2
We perform a feasibility study to probe dark matter (DM) production at the LHC within a global scotogenic model. The study is conducted using the Markov Chain Monte Carlo…
