Nucleon Resonance Electrocouplings from the CLAS Data on Exclusive Meson Electroproduction off Protons

$γ_{v}NN^*$ transition helicity amplitudes (electrocouplings) of several prominent excited proton states are determined for the first time in independent analyses of $π^+n$, $π^0p$, and $π^+π^-p$ electroproduction off protons. Analysis of $π^+π^-p$ electroproduction has extended considerably information on electrocouplings of high lying N* states, which decay preferentially to the $Nππ$ final states.
