Probing source and detector nonstandard interaction parameters at the DUNE near detector

We investigate the capability of DUNE near detector (ND) to constrain nonstandard interaction parameters (NSIs) describing production neutrinos $({ϵ}_{\ensuremath{\alpha}\ensuremath{\beta}}^{s})$ and their detection $({ϵ}_{\ensuremath{\alpha}\ensuremath{\beta}}^{d})$. show that ND is able reject a large portion parameter space allowed by far analyses set most stringent bounds from accelerator neutrino experiments on $|{ϵ}_{\ensuremath{\mu}e}^{s,d}|$ for wide intervals related phases. also provide simple analytic understanding our results as well numerical study dependence systematic errors, showing offers clean environment source NSIs.
