Short range correlations in the pion s-wave self-energy of pionic atoms

Article, Preprint English OPEN
Salcedo, Lorenzo Luis; Holinde, Karl; Oset Báguena, Eulogio; Schütz, C.;

We evaluate the contribution of second order terms to the pion-nucleus s-wave optical potential of pionic atoms generated by short range nuclear correlation. The corrections are sizeable because they involve the isoscalar s-wave $\pi N$ amplitude for half off-shell situ... View more
