A study of the photon structure function Fγ2(x, Q2) using two-dimensional unfolding

Description

Data taken with the ALEPH detector at LEP II have been used to measure the photon structure function Fγ2. The data were collected in 1997 at a centre-of-mass energy of √s ∼ 183 GeV and analysed in the two Q2 ranges from 7 to 24 and from 17 to 200 GeV2. To determine Fγ2, a two-dimensional unfolding method employing the principle of maximum entropy is used, which reduces the errors compared to one-dimensional methods. The results are compared to the predictions of several theoretical models
