Description
The e+e-->anti pp cross section has been measured in the energy interval (1975<=2E<=2250) MeV for vertical strokecosthetavertical stroke<0.7. The measurement is based on proportional100 events, thus improving by a factor 3 on the previous existing statistics in this energy interval. The form factor vertical strokeGvertical stroke2 is given as a function of energy under the assumption vertical strokeGsub(E)vertical stroke=vertical strokeGsub(M)vertical stroke. We also give the first measurement of the differential cross section, averaged over the energy interval, and estimate the ratio vertical strokeGsub(M)vertical stroke/vertical strokeGsub(E)vertical stroke from it.
