Electrons for Neutrinos: Lepton Energy Reconstruction in the Resonance Excitation Region
Description/Abstract/Artist Statement
A major area of research in nuclear/particle physics is the understanding of neutrino oscillations. The probability of measuring neutrinos to be in a particular state oscillates as they travel through space, and neutrino beam experiments are currently being run in an attempt to describe the nature of these oscillations. Neutrino beams cover a wide energy range, therefore a major obstacle for interpreting the results of these experiments is the determination of the incident neutrino energy. By using electron data with a known beam energy from the CLAS detector at the Thomas Jefferson National Accelerator Facility, and exploiting the leptonic similarities between electrons and neutrinos, we tested various techniques for determining the energies of incident leptons. We found that for events with only one electron, one proton, and one pion we could accurately reconstruct the energy only for negative pions. We were also only successful if we used information from all three particles. We will present data from various targets at beam energies of 2.2 and 4.4 GeV.
