Damping of the HERA effect in DIS?
P. Desgrolard, A. Lengyel, E. Martynov
Abstract
The drastic rise of the proton structure function F2(x,Q2) when the Björken variable x decreases, seen at HERA for a large span of Q2, negative values for the 4-momentum transfer, may be damped when Q2 increases beyond several hundreds GeV2. A new data analysis and a comparison with recent models for the proton structure function is proposed to discuss this phenomenon in terms of the derivative ∂ ln F2(x,Q2)/∂ ln(1/x).
