Measurement of the Hadronic Photon Structure Function at LEP 1 for $Q^{2}$ Values between 9.9 and 284 $GeV^{2}$

Inclusive gamma * gamma interactions to hadronic final states where one scattered electron or positron is detected in the electromagnetic calorimeters have been studied in the LEP 1 data taken by ALEPH from 1991 to 1995. The event sample has been used to measure the hadronic structure function of th...

Sumario:Inclusive gamma * gamma interactions to hadronic final states where one scattered electron or positron is detected in the electromagnetic calorimeters have been studied in the LEP 1 data taken by ALEPH from 1991 to 1995. The event sample has been used to measure the hadronic structure function of the photon F/sub 2//sup gamma / in three bins with <Q/sup 2/> of 9.9, 20.7 and 284 GeV/sup 2/. (31 refs).
