In this work we study the design of three stages used to read and amplifly the signals coming from 48 SiPM detectors connected in parallel. In the pre amplification stage, the charge integrator circuit and the trans-amplifier circuit are proposed, in the addition stage, a simple adder circuit; and, in the final stage, a low pass Sallen Key filter. A circuit analysis of the stages was done...
The radiative type-I seesaw has been already implemented to explain the lightness of Majorana neutrinos with both Majorana and Dirac heavy fermions, and the lightness of Dirac neutrinos with Dirac heavy fermions. In this work we present a minimal implementation of the radiative type-I seesaw with light Dirac neutrinos and heavy Majorana fermions. An inert doublet and a complex singlet scalar...
Deep Underground Neutrino Experiment (DUNE) is a facility to carry out studies related to neutrino science and proton decays. The proposed DUNE facility will consist of two neutrino detectors. The near detector is adjacent to beam source whereas far detector is 1300 Km downstream of the source in South Dakota. In near detector, interaction of Neutrinos with High Pressure Gas Time Projection...
In the Standard Model, we will deduce a configuration with five texture
zeros for the quark mass matrices that it is not of the Fritzsch type. It is valid and generates all the physical quantities of interest: that includes the quark masses, the inner angles of the Cabibbo-Kobayashi-Maskawa unitary triangle, and the phase responsible for the violation of the charge-parity symmetry. To achieve...
Connes’ noncommutative geometry (NCG) provides a rigorous framework to build the full Lagrangian of the Standard Model (SM) of particle physics. In this framework, there is an underlying finite space associated with each space-time point. Here, the Higgs field appears naturally as the “connection” linked with this new (dimensionless) space. Despite this achievement, in the minimal NCG SM...
The observation of Earth matter effects in the spectrum of neutrinos coming from a next galactic supernova could, in principle, reveal if neutrino mass ordering is normal or inverted. A way to identify these effects is through the observation of the modulations that appear in the spectrum when neutrinos travel through the Earth before they arrive at the detector. These features in the neutrino...
In a model where the right-handed neutrinos can propagate in a large compactified extra dimension and where the left-handed neutrinos are confined to a 4-dimensional spacetime, the oscillation probability in this model is $P_{\alpha\beta}=|\sum_{k=1}^3U^{\alpha k} U^{\beta k *} A_k|^2$, where $A_k=A_k(L,E_\nu,R_{LED}) = \sum_{n=0}^\infty (L_k^{0n})^2\exp(iL\lambda_k^{(n)2}/2E_\nu R^2)$. In...
We present a long term analysis of temporal evolution of the gamma-ray source W28, which is a supernova remnant (SNR) observed by the Large Area Telescope (LAT) on board of the Fermi Gamma-Ray Space Telescope since 2008. W28 is an old (3.5 - 4.5x104 yr) galactic diffuse gamma-ray source, located ~2kpc away from us, at (l:6.71, b:0.05) . Observed for more than 10 years, W28 is a interesting...
SiPM are devices widely used in great experiments on high energy physics to measure the energy related to a specific phenomenon and establish its characteristics. Now, an international collaboration leaded by Fermilab and CERN is working on DUNE project, which use high quantities of SiPM organized in structures; these structures operate as transduction paths for response of photon detection...
Presently, neutrinos are one of the most mysterious and interesting particles in physics, they seem to be the ones that can explain different processes of high energy physics, antimatter, conservation of energy and momentum in radioactive decay, and contribute with important data for cosmology and astrophysics. To better understand their different properties such as mass, parity, oscillations,...
Abstract:
A Deep Underground Neutrino Experiment (DUNE) facility is being set up at Fermi National Accelerator Laboratory. DUNE consisting of two massive particle detectors, one at Fermilab known as Near Detector (ND) and a much larger one to be constructed a mile underneath surface at the Sanford Underground Research Facility in South Dakota (Known as ‘Far Detector’). In the Near Detector,...
