Upper limits of the proton magnetic form factor in the time-like region from p̄p→ e +e - at the CERN-ISR

From the measurement of e +e - pairs from the reaction p̄p→e +e - at the CERN-ISR, using an antiproton beam and a hydrogen jet target, we derived upper limits for the proton magnetic form factor in the time-like region at Q 2⋍8.9( GeV c ) 2 and Q 2⋍12.5( GeV c ) 2 .
