Description
A long-baseline Deep Underground Neutrino Experiment (DUNE) is a novel and ambitious setup which will come-up in midwestern United State.This world class laboratory will not only address the fundamental questions about the nature of elementary particles and their role in the universe but it aims to announce groundbreaking discoveries.
In DUNE the measurements of neutrino oscillation parameters will be made by comparing the detected event rates in the far detector with the predictions made from the un-oscillated neutrino flux measured at the near detector. At a depth of around 1480m (4.30 km. w.e), the DUNE far detector will be the biggest liquid argon time projection chamber (TPC) detector. It will have the ability to look at the astrophysical objects through cosmic neutrinos which are hard to observe through other messenger particles and at the same time it will also search for Weakly Interacting Massive Particles (WIMPs) using neutrino-induced upward through-going muons. An understanding of the atmospheric neutrino background will be required to realize the goals of DUNE . As we know that meson decay results into production of neutrinos along with charged leptons hence neutrino background can be strongly constrained by the measurement of the atmospheric muon flux.
The existing direct and indirect methods of muon spectrometry at accelerator-based and cosmic-ray (magnetic spectrometers, transition radiation detectors) experiments involve certain technical problems and limitations in the higher energy region. These disadvantages vanish in this alternate method where the muon energy is estimated by measuring the energy of secondary cascades formed by muons losing their energy in the matter, mainly due to the Bremsstrahlung process. In this research work, we are attempting to implement this technique to reconstruct the muon energy and it’s direction at LArTPC proposed for DUNE.
