A study of the photon structure function $F_{2}^{\gamma}(x,Q^{2})$ using two-dimensional unfolding
Data taken with the ALEPH detector at LEP II have been used to measure the photon structure function $F_{2}\^{gamma}$. The data were collected in 1997 at a centre-of-mass energy of $\sqrt$ s=183 GeV and analysed in two Q2 ranges from 7 to 24 and from 17 to 200 GeV2. To determine $F_{2}\^{gamma}$, a...

| description | Data taken with the ALEPH detector at LEP II have been used to measure the photon structure function $F_{2}\^{gamma}$. The data were collected in 1997 at a centre-of-mass energy of $\sqrt$ s=183 GeV and analysed in two Q2 ranges from 7 to 24 and from 17 to 200 GeV2. To determine $F_{2}\^{gamma}$, 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 methods. |
