Abstract

The pion deep bound states are one of the most important systems to deduce the pion properties in nuclear medium. The pion-nucleon σ term can be determined, in principle, in the bound states by observing the modification of the pion properties at finite density. We investigate the possibility to determine the value of the pion-nucleon σ term precisely by the experimental observables of the deeply bound pionic atoms. We discuss the sensitivity of the observables to the σ term, and find that the gap of the binding energies and the width of the deep bound states are good quantities for the σ term determination.
