πd scattering lengths with taking into account of the pion and nucleon mass difference
Description
πd elastic scattering lengths and s-wave phase shifts are calculated in the framework of isotopically noninvariant approach taking into account the pion and nucleon isomultiplet mass splittings. It is shown that due to the mass differences of particles πd scattering lengths get imaginary parts (approximately 10-4 fm) which are not associated with pion adsorption. The mass splitting influence on the lengths and s phases is found tc be weakly dependent on the variation of the πN-potential parameters
