Title: Exclusive $π^{0} p$ electroproduction off protons in the resonance region at photon virtualities $0.4 {GeV}^{2} \leq Q^{2} \leq 1 {GeV}^{2}$

Abstract

The limited electroproduction process $e p \to e^{'} p^{'} π^{0}$ was measured in the range of photon virtualities $Q^{2} = 0.4 - 1.0 {GeV}^{2}$ and the invariant mass range of the $p π^{0}$ system of $W = 1.1 - 1.8$ GeV. These kinematics are covered in exclusive $π^{0}$ electroproduction off the proton with nearly complete angular coverage in the $p π^{0}$ center-of-mass system and with high statistical accuracy. Nearly 36 000 cross-section points were measured, and the structure functions $σ_{T} + ε σ_{L}, σ_{L T}$ , and $σ_{T T}$ , were extracted via fitting the $φ_{π^{0}}$ dependence of the cross section. A Legendre polynomial expansion analysis demonstrates the sensitivity of our data to high-lying $N^{*}$ and $Δ^{*}$ resonances with $M > 1.6$ GeV. As part of a broad effort to determine the electrocouplings of the $N^{*}$ and $Δ^{*}$ resonances using both single- and double-pion electroproduction, this dataset is key for the reliable extraction of the high-lying resonance electrocouplings from the combined isospin analysis of the $N π$ and $π^{+} π^{-} p$ channels.
