The Latin American Giant Observatory (LAGO) project consists of an extensive non-centralized network of Water Cherenkov Detectors (WCD) operated by a collaborative network of Universities and Research Institutes in Iberoamerica. The detectors of the network are built on the basis of commercial water containers, so they could have different geometries (but mostly cylindricals), different water...

The aim of this study is to investigate the correlation of the Ruppeiner geometry with recent conclusions about the thermodynamics of extremal black holes, focusing on the Reissner-Nordström solution. First, we studied the Ruppeiner geometry with respect to the "enthalpic" energy $M$ and the internal energy $\tilde{M}$, similar to the van der Walls-Maxwell model, this geometry allows us to...

In this work we show a study of the generation of neutrino masses is carried out from the Seesaw type II Mechanism for Dirac neutrinos. These mechanisms not only explain the mass of the neutrino but also its small value compared to charged quarks and leptons. Therefore, a model is proposed to obtain the small neutrino masses by extending the visible content of the Standard Model (SM) with a...

From Quantum Field Theory (QFT) for non-perturbative systems, the Schiwnger-Dyson equations (SDE) are obtained, which are analogous to the Euler-Lagrange equations in QFT, since they are the equations of motion of the Green's functions . The SDEs are an infinite set of integral equations coupled to each other and it is only possible to solve them by means of a truncation scheme. The...

In this work, we construct a traversable wormhole by providing a suitable embedding function ensuring the fulfilling of the flaring--out condition. The solution contains free parameters that are reduced through the study of the acceptable conditions of a traversable wormhole. We compute both the quantifier of exotic matter and the quasi--normal modes through the $13^{th}$ order WKB as a...

In order to study systematic errors of the detector, we have estimated the Electron Shaking Probability (ESP) in the L-capture peak of the 7Be nuclear EC decay... -

symplectic formalism quantization method determine the zero modes
of the symplectic matrix and the generators of the gauge
transformation. After fixing the null-plane gauge, the generalized
brackets are calculated and the commutation relations of the theory
are deduce. -

In this work, we have assumed special structures for the charged and neutral mass matrices in the lepton sector, inspired by structures for the up and down quark mass matrices that result by assuming a certain number of symmetrical zeros in their entries named texture zeros. A prediction of the lepton mixing matrix results from the rotation matrices that diagonalize the mass matrices in the...

The Latin American Giant Observatory (LAGO) operates a network of water Cherenkov detectors (WCD) at different sites in Latin America. Spanning over different latitudes, altitudes and geomagnetic rigidity cutoffs. LAGO detectors at high altitudes have good sensitivity to electromagnetic secondary radiation that is the expected signature of this kind of high energy events. The spanning of LAGO...

Astroparticles impinging on the Earth atmosphere cause a flux of secondary particles composed of three main components: electromagnetic, muonic and hadronic. When entering a Water Cherenkov Detector (WCD), these particles create Cherenkov radiation that is measured by photomultiplier sensors. The raw information captured by WCDs provides valuable insights into the temporal evolution of the...

Subsequent to the release of CERN Open Data, the emergence of a variety of challenges awakened the curiosity and interests of scientists from different disciplines to attack them from their own expertise, among them computer science. The past few years have seen a high growth in the take-up of ML by the accelerator community in Deep Learning developments, for ML is noticeably a key tool to...

following the method used by Sirlin. Radiative corrections can be separated into model-independent and model-dependent parts. Here we consider only the independent part of the model and the Dalitz plot of this decay is obtained from it. This method has been... -

We present a detailed study of a proposed model to explain the experimental hints of new physics in B meson decays within the frameork of the Pati-Salam unification. The model is based on the local gauge group $\mathrm{SU}(4)_L \otimes \mathrm{SU}(4)_R \otimes \mathrm{SU}(2)_L \otimes \mathrm{U}(1)'$ and part of its gauge bosons are $(3,1)_{2/3}$ vector leptoquarks. The key feature of the...

In this work we study an effective version of the 3-3-1 model, in which the particle content is the same of the 2HDM. We show that the inherited structure from the $SU(3)_C \otimes SU(3)_L \otimes U(1)_X$ gauge group has a series of consequences, the most relevant one being the prediction of the masses of the neutral scalar to be of the order or lower than the mass of the charged scalar. Given...

Muography is a non-invasive scanning technique that uses the directional flux of secondary atmospheric muons as a source to scan the density variations of objects on scales ranging from hundreds to thousands of meters. Cosmic ray detectors for muography use two or more planar detectors divided into several detection pixels (on the order of a few square centimeters) operating in coincidence...

We review in a systematic way how anomaly free $SU(3)_c\otimes SU(3)_L\otimes U(1)_x$ models without exotic electric charges can be constructed, using as basis closed sets of fermions which includes each one the particles and antiparticles of all the electrically charged fields. Our analysis reproduces not only the known models in the literature, but also shows the existence of several more...

Lee-Wick (LW) standard model (LWSM) renormalizes the Standard model with the addition of new partner fields with negative metric. The model predicts a phenomenon denominated as wrong displaced vertices (WDV) also known as acuasally displaced vertices. In this work, we modeled and characterized the signal coming from the pair production of electron LW-partners (LW-electrons) emitted from the...
