Spectral function sum rules from current algebra, unitarity and analyticity
With the assumptions of SU(2)*SU(2) current algebra, conservation of the vector currents, PCAC and finiteness of the Schwinger terms C/sub V/ and C/sub A/, some restrictions of unitarity and analyticity on hard pion current algebra models are obtained for the specific case of the pion form factor.
