Electron Neutrino Classification in Liquid Argon Time Projection Chamber Detector
نویسندگان
چکیده
Neutrinos are one of the least known elementary particles. The detection of neutrinos is an extremely difficult task since they are affected only by weak sub-atomic force or gravity. Therefore large detectors are constructed to reveal neutrino’s properties. Among them the Liquid Argon Time Projection Chamber (LAr-TPC) detectors provide excellent imaging and particle identification ability for studying neutrinos. The computerized methods for automatic reconstruction and identification of particles are needed to fully exploit the potential of the LAr-TPC technique. Herein, the novel method for electron neutrino classification is presented. The method constructs a feature descriptor from images of observed event. It characterizes the signal distribution propagated from vertex of interest, where the particle interacts with the detector medium. The classifier is learned with a constructed feature descriptor to decide whether the images represent the electron neutrino or cascade produced by photons. The proposed approach assumes that the position of primary interaction vertex is known. The method’s performance in dependency to the noise in a primary vertex position and deposited energy of particles is studied.

Neutrinos have been a source of excitement lately. While the neutrino mixing has been expected, its pattern has taken us by surprise. The first evidence of physics beyond the standard model is here and more excitement is likely on the way.. Fermilab has a unique opportunity to take a lead in the neutrino physics in the next decade or so. Our recent major investments put us in an envi-able posit...

We constructed and operated a double phase (liquid-vapour) pure argon Large Electron Multiplier Time Projection Chamber (LAr LEM-TPC) with a sensitive area of 10x10 cm2 and up to 30 cm of drift length. The LEM is a macroscopic hole electron multiplier built with standard PCB techniques: drifting electrons are extracted from the liquid to the vapour phase and driven into the holes of the LEM whe...

Recent results from SNO [1] and KamLAND [2] confirm the large mixing angle MSW solution to the solar neutrino problem, which implies that the full 3-generation neutrino mixing matrix can be studied in a new generation of accelerator-based neutrino experiments. A particular opportunity for this is to place a new, large (20 kton or more) neutrino detector in a NuMI off-axis beam [3], where parame...
