Abstract: Secret interactions of neutrinos with light new gauge bosons, Z, can lead to a rich phenomenology in a supernova explosion as well as in the early Universe. This interaction can also lead to new decay modes for charged mesons, π+(K+)e+νZ, and subsequently to Zνν¯. After demonstrating that such an interaction can be accommodated within viable electroweak symmetric models, we study how the near detector (ND) of DUNE can probe this scenario. We also discuss how the DUNE ND can make it possible to reconstruct the flavor structure of the Z coupling to neutrinos.
