Pionic effects in deep inelastic scattering off nuclei
P. Gonzalez, V. Vento
Abstract
The structure functions calculated in the Chiral bag model reproduce quite well, after appropriate perturbative evolution to large energy scales, the experimental data. We use these results to interpret the structure of the EMC data as a quenching of the pion decay constant due to the in medium behavior of the nucleon. This explanation supports recent proposals of this phenomenon whose origin is the scale invariance of the QCD lagrangian.
