The DIRAC experiment at CERN has achieved a sizeable production of $\pi^+\pi^-$ atoms and has significantly improved the precision on its lifetime determination. From a sample of 21227 atomic pairs, a 4% measurement of the S-wave $\pi\pi$ scattering

$\pi NN$ and $\pi N\Delta$ formfactors determined from a microscopic model for $\pi N$ scattering

Autor: Schütz, C., Holinde, K.

Publikováno v: Phys.Rev.C54:1561-1565,1996

We determine the $\pi NN$ and $\pi N\Delta$ formfactors from the $P_{11}$ resp. $P_{33}$ partial wave of $\pi N$ scattering by dressing corresponding bare vertices with the help of $\pi N$ non--pole contributions. The underlying model is based on mes

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

Autor: Salcedo, L. L., Holinde, K., Oset, E., Schütz, C.

Publikováno v: Phys.Lett. B353 (1995) 1-6

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
