The prospect for studying $n\pi^{+}\pi^{0}$ electroproduction off protons with CLAS12

Investigation of double-pion electroproduction channel is a very efficient tool for exploration of nucleon structure that includes the study of nucleon resonances. The experiments conducted with the CLAS detector have already provided a lot of data on the cross sections of the reaction $\gamma_{v} p \rightarrow p'\pi^{+}\pi^{-}$. Their interpretation within the phenomenological model has delivered valuable information on nucleon resonances electrocouplings. Another promising channel, for the $n\pi^{+}\pi^{0}$ final state, has not yet been investigated using the CLAS detector due to the limited angular coverage of $\pi^{0}$ detection. The cross section of this so far unexplored channel benefits from larger relative resonant contribution comparing to the reaction with the $p\pi^{+}\pi^{-}$ final state. New opportunities for studying the $n\pi^{+}\pi^{0}$ final state are possible with the CLAS12 detector, which has significantly larger angular coverage for $\pi^{0}$ detection than CLAS. The study of a new channel requires an adaptation of the experimental analysis tools and the phenomenological reaction model which were previously established for $\gamma_{v} p \rightarrow p'\pi^{+}\pi^{-}$ channel. The status of this activity will be presented in the talk.
