Electrons For Neutrinos: New Experiments at Jefferson Lab

The Electrons for Neutrinos project (e4nu) at the Thomas Jefferson National Accelerator Facility (JLab) uses wide phase space exclusive electron scattering data from past and future experiments on nuclear targets with the CLAS and CLAS12 detector systems to obtain a comprehensive understanding of the interaction of leptons with matter. Data from JLab provides us with the means to constrain the available theoretical tools that are crucial in modeling the neutrino-nucleus interaction, and thus play a key role in the precise determination of the physics observables from neutrino-nucleus interactions measured at current and future neutrino experimental facilities, including MicroBooNE, MINERvA, DUNE and T2K.

We will discuss the next phase of the e4nu project, taking new dedicated data with CLAS12 at JLab. We will take data with 1, 2, 4, and 6 GeV beams, on Deuterium, Oxygen, Carbon and Argon targets, greatly expanding the available data. The first phase of this experiment will take place in Fall 2021.
