η' and η mesons T-dependence QCD topological susceptibility isospin symmetry
Sažetak
Exploring the extent of model dependence, we study effects of certain Ansätze for the T-dependence of the correction term in the QCD topological susceptibility. The one producing unwanted effects on results at T > 0 in the η'-η complex in the usual limit of isospin symmetry, is largely cured from its peculiar behavior and brought into agreement with the other, when breaking of isospin symmetry is allowed and the realistic quark mass ratio m_u/m_d = 0.50 is adopted.
