A Thermodynamical Analysis Of The Pi-Meson And K-Meson Valence Structure Functions

The π and K meson valence structure functions are analysed in the framework of a thermodynamical model already applied to the nucleon. We obtain a simple expression which reproduces quite well the data for x > 0.3. The effective temperatures are found to be of the order of 20 MeV for the pion and 65 MeV for the kaon.
