The pion structure function from the statistical model of the hadron and correlation between temperature and q2 by the Gottfried sum rule

In the present work the method used in ref. [1] is considered to obtain the function structure of pion F2π 2 , In that model, it was needed an initial quark distribution and the observed distribution in the hadron. This method provides information about the sea quark distribution of mesons that are out of reach experimentally. The pion structure is determined fairly acc urated. The initial distribution for the anti-d quark may given by the thermal model ref. [2,3]. We compare our results with other models to describe the pion structure function ref. [4,5] and with the experimental data on pion structure. We also studied if there is a relation between the q2 and the measured violation of the Gottfried sum rule. Also, a comparison between the relations Gott x q2 and Gott x T, where the T is the temperature given by a statistical model ref.[1,2] is done. On this way, it is expected to understand if there is a relation q2 x T [3,4], that would mean that the scattering heats the hadron. (author)
