The status of the current and future searches of light bosons is reviewed. I will focus on light bosons acting as the dark matter or the dark energy in the Universe

Many scenarios of physics beyond the Standard Model predict new particles with

masses well below the electroweak scale. Low-energy, high luminosity colliders such as BaBar are ideally suited to discover these particles. We present several recent searches for low-mass dark sector particles at BaBar, including leptophilic scalars, self-interacting dark matter bound states, and axion like... -

Primordial black holes (PBHs) are a potential dark matter candidate whose masses can span over many orders of magnitude. If their masses lie in the $10^{15}-10^{17}$ g range, they can emit sizeable fluxes of MeV neutrinos through evaporation via Hawking radiation. We investigate the possibility of detecting light (non-)rotating PBHs with future neutrino experiments DUNE and THEIA. We show that...

Dark Matter and neutrinos are one of the most puzzling components of the Universe. We study a realization of the scotogenic model for neutrino masses using a $U(1)$ gauge symmetry between muon and tau fermion. The model contains 3 possible WIMP Dark Matter candidates: A majorana fermion, a CP-even and a CP-odd scalar. We consider a basic set of observables to constrain the model, and we make...

We propose a model with spin 3/2 fermions and vector doublets. We compute neutrino masses via radiative seesaw mechanism. We investigate the consequences of the model in the dark matter relic abundance. Furthermore, we implement the Casas-Ibarra parametrization to constraint the parameter space considering theoretical constraints. We also analyze the parameter space for direct detection of dark matter.

We study the possible searches of dark matter at colliders using Vector Boson Fusion topology in the context of Simplified Models signatures. We examine the possible physics reach of these searches with regard to monojet-type searches, and determine how these two signatures might be complementary.

A proposal is presented for a dark matter (DM) signal search with the Phase-2 CMS Detector at the high luminosity LHC. The model under study includes a scalar field and new particles heavy fermions. Deep neural networks are constructed for the study of the experimental signature consisting of one or two muons in the presence of lost transverse moment. The results of these models are compared...

In recent years the multicomponent scalar dark matter models with discrete symmetries $\mathbb{Z}_N$ has been widely studied in the literature. Among them, the $\mathbb{Z}_5$ model proposes two complex fields that transform as singlets under the gauge group of Standard Model. The model has eleven free parameters that must be restricted. In that sense, the main purpose of this research is to...

We consider a model with Left-Right symmetry with $SU(3)C\times SU(2)_R\times SU(2)_L\times U(1)_{Y^\prime}$ gauge group that includes an additional fermions which are charged under the $SU(2)_R$. The model and their fields charged under $SU(2)_R$ are known as Left−Right Mirror Model (LRMM) and mirror fermions, respectively. Although the motivation for introducing LRMM was to analyze the CP...

In canonical Left-Right gauge model with only one $SU(2)_L $ Higgs doublet and one $SU(2)_R$ scalar doublet, there is no tree level fermion masses. The universal scotogenic Left-Right gauge model is able to generate all the SM fermion masses radiatively via a dark sector generated through a $U(1)_D$ global dark symmetry. We study the dark matter phenomenology in this model, performing a...

Actualmente se considera que la materia oscura (DM) es uno de los principales componentes del universo, sin embargo, su origen y naturaleza sigue siendo una pregunta abierta, ya que la DM no forma parte del modelo estándar de las partículas elementales (SM). En este trabajo se propone que la DM se genera, no en un escalar, sino por co-aniquilación de neutrinos pesados de Majorana, a través del...
