A measurement of the production of massive e$^{+}$e$^{-}$ pairs in proton-proton collisions at $\sqrt{s}$ = 62.4 GeV

An apparatus consisting of a superconducting solenoid magnet, cylindrical drift-chambers, and two arrays of lead-glass Cerenkov counters has been used at the CERN ISR to study the production of e /sup +/e/sup -/ pairs of invariant mass above 6.5 GeV/c/sup 2/. Cross sections for the continuum and the...

Descripción
Sumario:An apparatus consisting of a superconducting solenoid magnet, cylindrical drift-chambers, and two arrays of lead-glass Cerenkov counters has been used at the CERN ISR to study the production of e /sup +/e/sup -/ pairs of invariant mass above 6.5 GeV/c/sup 2/. Cross sections for the continuum and the Upsilon family of resonances are presented, as well as the mean transverse momentum (p/sub T/) of the electron-positron pairs in the continuum and resonance region.
