NEXT-100 is an electroluminescent high-pressure xenon gas time projection chamber that will search for the neutrinoless double beta (0νββ) decay of 136Xe. The detector possesses two features great value 0νββ searches: energy resolution better than 1% FWHM at Q 136Xe and track reconstruction discrimination signal background events. This combination results in excellent sensitivity, as discussed this paper. Material-screening measurements a detailed Monte Carlo simulation predict rate most 4 ×...
The NEXT experiment aims to observe the neutrinoless double beta decay of 136Xe in a high-pressure xenon gas TPC using electroluminescence (EL) amplify signal from ionization. One main advantages this technology is possibility reconstruct topology events with energies close Q ββ . This paper presents first demonstration that provides extra handles reject background data obtained NEXT-DEMO prototype. Single electrons resulting interactions 22Na 1275 keV gammas and electronpositron pairs...
We investigate the potential of using deep learning techniques to reject background events in searches for neutrinoless double beta decay with high pressure xenon time projection chambers capable detailed track reconstruction. The differences topological signatures and signal can be learned by neural networks via training over many thousands events. These then used classify further as or background, providing an additional rejection factor at acceptable loss efficiency. trained this study...
Single neutral pion production via muon antineutrino charged-current interactions in plastic scintillator (CH) is studied using the \minerva detector exposed to NuMI low-energy, wideband beam at Fermilab. Measurement of this process constrains models nuclei, which important because neutral-current analog a background for $\bar{\nu}_e$ appearance oscillation experiments. The differential cross sections $\pi^0$ momentum and angle, events with single observed no charged pions, are presented...

ANTARES is actually the fully operational and largest neutrino telescope in Northern hemisphere. Located Mediterranean Sea, it consists of a 3D array 885 photomultiplier tubes (PMTs) arranged 12 detection lines (25 storeys each), able to detect Cherenkov light induced by upgoing relativistic muons produced interaction high energy cosmic neutrinos with detector surroundings. Among its physics goals, search for astrophysical sources indirect dark matter particles coming from sun are particular...
Silicon Photomultiplier (SiPM) is a photodetector with very high sensitivity, fast response and good performance in oversaturation conditions. When SiPM faces incident optical radiation (sometimes imperceptible for other photodetectors) able to detect small variations of light. In this work, we present SiPM-based receiver ables discriminate light signals from background noise, while exposed ambient conditions without filters or another additional device. Such device the core new high-speed...
