Abstract :
We apply the linear sigma model to analyze pion-nuclon sigma-term. Analytic expressions for these quantities are obtained in terms of the parameters of low energy physics (pion decay constant and the pion mass). Good results have been obtained in comparison with my previous works and with the other models.
