Study of the hadronic photon structure function F<sup>γ</sup><sub>2</sub> at LEP

The hadronic photon structure function F<sup>γ</sup><sub>2</sub> is studied in the reaction e+e− → e+e−hadrons at LEP with the L3 detector. The data, collected from 1991 to 1995 at a centre-of-mass energy √s = ≃ 91 GeV, correspond to an integrated luminosity of 140 pb<sup&...

Sumario:The hadronic photon structure function F<sup>γ</sup><sub>2</sub> is studied in the reaction e+e− → e+e−hadrons at LEP with the L3 detector. The data, collected from 1991 to 1995 at a centre-of-mass energy √s = ≃ 91 GeV, correspond to an integrated luminosity of 140 pb<sup>−1</sup>. The photon structure function F<sup>γ</sup><sub>2</sub> is measured in the Q<sup>2</sup> interval 1.2 GeV<sup>2</sup> ≤ Q<sup>2</sup> ≤ 9.0 GeV<sup>2</sup> and the x interval 0.002 < x < 0.2. F<sup>γ</sup><sub>2</sub> shows a linear growth with lnQ<sup>2</sup>. The value of the slope α<sup>−1</sup>dF<sup>γ</sup><sub>2</sub>(Q<sup>2</sup>)/dlnQ<sup>2</sup> is measured to be 0.079±0.011±0.009.
