Description

Forty directly produced electron pairs have been found by following 713.4 m of 200-GeV-proton track length in nuclear emulsion. For these pairs we have analyzed (i) the total energy distribution, (ii) the energy partition between the two members, (iii) the angular divergence, (iv) the transverse momentum distribution, and (v) the invariant mass of the electron pairs. Present theories disagree with our experimental results.
