| Abstract: | A new procedure is devised to evaluate the proton form-factor at the ¯pp threshold from experimental data on ¯pp  e+e– annihilation at rest. Comparison of the ¯ppe+e– and¯pp +– processes reveals that annihilation ranges for various channels are ranked in line with quark dynamics.This work has been funded in part by the German Federal Minister for Research and Technology (BMFT) under the contract number 06HD756 |
