Description

Recent data on π p elastic scattering at 200 GeV/c from Fermilab allow a further application of the Chou-Yang relation between scattering amplitudes and form factors. Using a carefully selected parametrization of the elastic amplitude, we find that the pion form factor has a zero for vertical stroketvertical stroke between 15 and 20 (GeV)2. In order to locate this zero accurately, more experimental data at large momentum transfers are needed. (orig.)
