Role of the gauged linear $σ$-model as an underlying field theory model describing nucleon structure and elastic scattering is discussed. Possibility of finding evidence of a chiral phase transition at large $|t|$ in the proposed TOTEM project at LHC is pointed out.Presented at the Fifth Workshop on QCD, Villefranche, France, Jan. 2000 (to be published in Proceedings of the Workshop)High Energy Physics - Phenomenologytext
