Sensitivity Studies for the search of Fractional Charge Particles in DUNE Near Detector using ProtoDUNE data experience

This project studies the sensitivity of the Near DUNE Detector for fractional charges. As suggested by the BC3 model of the Vector Portal Model in Beyond standard model there is existence of Milli-Charged Particle(mCP) reflecting the evidence from Dark Matter, which motivated and made the searches of fractional charges very interesting. Also, as the fractional charges have interaction similar to Neutrinos, they both are weak interactive particles. We are searching for them in DUNE Near Detector, which is highest sensitive detector proposed so far. It is a very massive at the same time. As these particles don’t stop inside the detector, more the mass inside detector more the interaction hits and more chances to observe them. It’s sensitivity enable us to differentiate even very low energy interactions from the noise. Having motivation to detect mCP we are studying this fractional charge sensitivity of the DUNE Near Detector. For studying the performance of DUNE Near Detector and DUNE far Detector coming up at Fermilab, a prototype model is made at CERN. We are using the ProtoDUNE data experience to search for the fractional charges in DUNE Near Detector. DUNE software will differ from the ProtoDUNE in terms of noise response and other technical matters but the basic idea will remain same. So these studies can be very useful and interesting to search fractional charges and New Physics at DUNE Near Detector in the future.
