SND@LHC is a compact and stand-alone experiment to perform measurements with neutrinos produced at the LHC in a hitherto unexplored pseudo-rapidity region of 7.2 < η < 8.6, complementary to all the other experiments at the LHC. The experiment is to be located 480 m downstream of IP1 in the unused TI18 tunnel. The detector is composed of a hybrid system based on an 800 kg target mass of...
The Deep Underground Neutrino Experiment (DUNE) international project, currently under construction, will enable an exciting program for precision neutrino physics and beyond. Two multidetector facilities will be exposed to the world's most intense neutrino beam: the Near Detector complex will measure the beam flux and composition 575 m downstream of the production target, at Fermilab; and the...
Interactions from neutrino-beam with liquid argon are critical backgrounds in the detection of long-lived bosons at DUNE-ND. In this work, we examine the influence of neutrino-electron scattering and ve-CCQE events in search of dark photons as portals of multicomponent light dark matter using the main attributes of DUNE-PRISM.
The Deep Underground Neutrino Experiment (DUNE) is an international collaboration under construction in the USA. Colombian institutions are involved in the development of the DUNE experiment and are a good example of how Latin American countries can contribute efectivelly to a mega-science experiment. This talk summarizes the Colombian activities in the design of the front-end readout...
An ongoing program for additional measurements of coherent elastic neutrino-nucleus scattering (CEvNS) is currently under development. Experimental facilities include nuclear power plants, multiton dark matter detectors as well as Ge and NaI detectors at the spallation neutron source. These experiments will provide information on nuclear properties, standard model parameters and the possible...
The CONNIE experiment uses fully depleted high-resistivity CCDs with the goal of detecting the coherent elastic neutrino nucleus (CEvNS) scattering of reactor antineutrinos off silicon nuclei, and to probe physics beyond the Standard Model (SM). It is located at 30 m from the core of the 3.8 GW Angra 2 nuclear reactor in Brazil. Since its 2016 upgrade, the experiment has operated with a low...
We report on an update (2021) of a phenomelogical model for inelastic neutrino- and electron-nucleon scattering cross sections using effective leading order parton distribution functions with a new scaling variable $\xi_w$. Non-perturbative effects are well described using the $\xi_w$ scaling variable in combination with multiplicative $K$ factors at low $Q^2$. The model describes all...
In this talk, I will present the current status of global analyses to neutrino oscillation data in the three-flavor framework. I will discuss the recent hints in favor of normal mass ordering and maximal CP violation as well as the different tensions we find when combining different data samples. The robustness of the current oscillation picture in the presence of new physics beyond the...
The Scotogenic model is an economical scenario that generates neutrino masses at the 1-loop level and includes a dark matter candidate. This is achieved by means of an ad-hoc $\mathbb{Z}_2$ symmetry, which forbids the tree-level generation of neutrino masses and stabilizes the lightest $\mathbb{Z}_2$-odd state. Neutrino masses are also suppressed by a quartic coupling, usually denoted by...
The neutrino mass ordering is one of the most pressing unknowns in neutrino physics. This measurement is a flagship of the JUNO reactor neutrino oscillation experiment. In this talk we will discuss the role JUNO can play in the unraveling of the neutrino mass ordering at 3$\sigma$ or better before the end of the decade.
