B.A. Li (Department of Physics, Univ. of Kentucky)
TL;DR
This paper predicts the ten coefficients of chiral perturbation theory using an effective theory without introducing new parameters, also determining key quark masses and decay constants.
Contribution
It provides a parameter-free prediction of ChPT coefficients and determines important quark masses and decay constants.
Findings
Predicted all ten ChPT coefficients.
Determined current quark masses m_{ ext{quark}}.
Calculated decay constants f_{K} and f_{ ext{eta}}.
Abstract
Based on an effective chiral theory the 10 coefficients of ChPT are predicted. There is no new parameter. The current quark masses, m_{\eta}, f_{K}, and f_{\eta} are determined too.
