Measurement of the Charge-Averaged Elastic Lepton-Proton Scattering Cross Section by the OLYMPUS Experiment

J. C. Bernauer, A. Schmidt, B. S. Henderson +67

We report the first measurement of the average of the electron-proton and positron-proton elastic scattering cross sections. This lepton charge-averaged cross section is insensitiv…

Decay pion spectroscopy: a new approach

A. Margaryan, R. Ajvazyan, N. Grigoryan +12

We propose a new experiment for decay pion spectroscopy of light hypernuclei at electron- and proton-beam facilities, using the recoil distance technique for separation of produced…
