Direct electron-positron pair production by 200-GeV negative pions

Journal Article

We have studied direct electron-positron pair production by the collision of 200-GeV - mesons with a neon target. The data consist of 622 direct pairs with momenta ranging from 10 MeV/c to 7.5 GeV/c. We have measured the total production rate to an accuracy of 10% and studied the relevant momentum and electron-positron momentum partition spectra. In contrast to several recent experiments, we find excellent agreement with the predictions of quantum electrodynamic calculations. © 1975 The American Physical Society.
