Several theoretical models inspired by the idea of supersymmetry (SUSY) accommodate the possibility of HSCPs (Heavy Stable Charged Particles). The phase-II upgrade of the CMS-RPC system will allow the trigger and identification of this kind of particles exploiting the Time of Flight Technique with the improved time resolution that a new DAQ system will provide (~2ns). Moreover, new RPC...

Extensions of the SM have been suggested to solve questions of the modern particle physics like the origin of the neutrino masses, one of this extensions is the neutrino Minimal SM ($\nu MSM$). In the $\nu MSM$ every left-handed fermion has a right-handed counterpart, that can be responsible form neutrino masses, dark matter and baryogenesis. In this talk a summary of the searches for HNL in...

We study systematically the models for Dirac neutrino masses with minimal fields and symmetries. Some of them can accommodate dark matter candidates.

We present the most general solutions for the charges of a $Z'$ with a minimal content of fermions. From our analysis,

we show the existence of three different scenarios which, as far as we know, are new in the literature.

However, these solutions reduce to very well-known cases for particular choices of the free parameters.

We also define several benchmark models in order to show the...

We present a simplified dark matter (DM) model that arises from the interplay of a Majorana triplet and a vector-like doublet, both odd under a $Z_2$ symmetry that stabilizes the DM. The region where DM mass lies at the electroweak scale is severely constrained from relic abundance and Higgs diphoton decay. For this reason, we study the model within the framework of non-standard cosmology,...

Connes' noncommutative geometry (NCG) provides a complete picture to build the full standard model (SM) of particle physics by adding some discrete dimensions to the underlying four-dimensional (continuous) space-time. Within this framework, one can go further and construct models beyond the standard model. But this task is very constrained since all the axioms of the theory must be satisfied....

Given the elusive nature of Dark Matter (DM), indirect measurements are the most common approach to study it observationally. However, to make these studies possible, some assumptions must be made. These assumptions come from complicated theoretical frameworks and the analysis of state-of-the-art cosmolofical simulations. In this work we study the shape of the DM halo of Milky Way-like...

The search for dark matter is a joint quest between particle physics and astrophysics.

From astrophysical evidence we know that the dark matter particle should be outside the standard model.

Nevertheless, the dark matter particle should have well defined particle properties including its cross section.

This means that dark matter must be collissional to some degree.

However, dark matter has...

Since the pioneering work of Tremaine & Gun to the present, many approaches has been presented to constrain the dark matter (DM) particle mass from its phase-space density (PSD) evolution until the virialization of DM halos today. In particular, in the context of recent numerical simulations of fermionic DM particles, developed to investigate the effects of primordial thermal velocities of...

A search for dark matter production in association with a Higgs boson

decaying to $b$-quarks is performed using $pp$ collisions at a centre-of-mass

energy of $\sqrt{s}=13\,\mathrm{TeV}$. The dataset has an integrated

luminosity of $80\:\mathrm{fb^{-1}}$and was recorded with the ATLAS

detector at the Large Hadron Collider. Selected collision events comprise

large missing transverse momentum and...

This talk will present the importance of Vector Boson Fusion, as a potential discovery tool for Dark Matter and New Physics at the LHC.

We consider a scenario in which the inflaton is a pseudoscalar field non-minimally coupled to gravity and to an emsamble of U(1) gauge fields through axial couplings. It is well known that the presence of axial couplings leads to a production of gauge particles which acts as a friction term in the dynamics of the inflaton, producing a slow-roll regime even in presence of a steep potential and...

Choosing OnShell Renormalization Scheme in the Complex MSSM.

We analyze the possible choices of on-shell (OS) renormalization schemes (RS)

in the chargino/neutralino sector of the the Minimal Supersymmetric Standard Model with complex parameters (cMSSM). These RS have been implemented in the FeynArts/FormCalc (FA/FC) package. However, the specific choice needs to be set manually by the user,...

El Modelo Estándar (ME) es una teoría de física de partículas cuyo aspecto más significativo es la unificación de tres de las cuatro fuerzas fundamentales de la naturaleza: la fuerza nuclear fuerte, la fuerza nuclear débil y el electromagnetismo. Es una teoría que, a bajas energías, otorga una descripción satisfactoria del comportamiento del universo. Sin embargo, existen varios fenómenos que...
