Room: 4-2-037 - TH meeting room We set constraints on millicharged particles (mCPs) based on electron scattering data from MiniBooNE and the Liquid Scintillator Neutrino Detector (LSND) Both experiments are found to provide new (and leading) constraints in certain mCP mass windows: 5 - 35 MeV for LSND and 100 - 180 MeV for MiniBooNE
