I will describe a low scale renormalizable extended left-right symmetric theory where the observed SM fermion mass hierarchy arises from a seesaw-like mechanism and the light active neutrino masses are generated from a radiative inverse seesaw. I will discuss its implications in charged lepton flavour violation, in the lepton and baryon asymmetries of the Universe, in the muon and electron...
We present a model based on an implementation of supersymmetry where matter fields are in the adjoint representation. We will discuss some of the details of the construction. We present a GUT model based on the conformal superalgebra. We present exact black-hole solutions, gravitating spinor solutions and non-trivial gauge configurations. We discuss the issue of anomalies in the context of GUT models.
Leptoquarks are predicted by many new physics theories to describe the similarities between the lepton and quark sectors of the Standard Model and offer an attractive potential explanation for the B-physics anomalies observed at LHCb and flavour factories. The ATLAS experiment has a broad program of direct searches for leptoquarks, coupling to the first-, second- or third-generation particles....
Many new physics models predict the existence of resonances decaying into two bosons (W, Z, photon, or Higgs bosons) making these important signatures in the search for new physics. Searches for Vy, VV, and VH resonances have been performed in various final states. In some of these searches, jet substructure techniques are used to disentangle the hadronic decay products in highly boosted...
Supersymmetry (SUSY) provides elegant solutions to several problems in the Standard Model, and searches for SUSY particles are an important component of the LHC physics program. This talk will present the latest results from SUSY searches conducted by the ATLAS experiment. The searches target multiple final states and different assumptions about the decay mode of the produced SUSY particles,...
Various theories beyond the Standard Model predict new, long-lived particles with unique signatures which are difficult to reconstruct and for which estimating the background rates is also a challenge. Signatures from displaced and/or delayed decays anywhere from the inner detector to the muon spectrometer, as well as those of new particles with fractional or multiple values of the charge of...
I will present two models where light active neutrino masses are radiatively generated. In the first one the light active neutrino masses are generated at one loop level via a radiative seesaw mechanism mediated by the neutral components of the SU(3)L leptonic Octet and electrically neutral scalars. These SU(3)L leptonic Octet is crucial for achieving successful gauge coupling unification. The...
There are many models trying to explain some of the main current questions in physics. The scotogenic model presents both an explanation to neutrino masses and provides a dark matter candidate that can be a scalar or a fermion. In this work we focus on a real scalar as the dark matter candidate which is generated in a thermal freeze-out scenario. We study the parameter space of the model...
