Double-logarithmic Scaling of the Structure Function F2 at small x
W. Buchmuller, D. Haidt
Abstract
Recent data on the structure function F2(x,Q2) at small values of x are analysed and compared with theoretical expectations. It is shown that the observed rise at small x is consistent with a logarithmic increase, growing logarithmically also with Q2. A stronger increase, which may be incompatible with unitarity when extrapolated to asymptotically small values of x, cannot be inferred from present data.
