Electrons and muons for neutrinos

Sensitivities of future large underground neutrino oscillation experiments at long baselines are critically dependent upon precisely understanding the initial energy of an incoming neutrino via cross section models and event generator predictions which summarize prospective final states.
These include the reconstruction of the incident neutrino energy from the measured final state particles. Incomplete understanding of these interactions can skew the reconstructed neutrino spectrum and thereby bias the extraction of fundamental oscillation parameters and searches for new physics. The Electrons-for-Neutrinos and Muons-for-Neutrinos Initiatives aim to constrain the existing models by studying the light charged leptonic cousins of the neutrino, exploiting universal vector-like interactions to better understand underlying systematic modeling uncertainties, improve neutrino cross sections models, and calibrate reconstruction techniques in situ.
