On the interpretation of the CHARM II data

The data of the CHARM II and of the ALEPH, DELPHI, L3 and OPAL Collaborations are compared in the framework of ( α( m_Z), m_Z, G_μ, m_t, m_H)-parametrization of the electroweak radiative corrections. The comparison shows that the physical meaning of the CHARM II results is more significant than was stated in the original publication of the CHARM Collaboration. In particular, CHARM II is very sensitive to the Z boson coupling to the muon neutrinos.
