New method for fitting the low-energy constants in chiral perturbation theory

A new set of the next-to-leading order (NLO) and the next-to-next-to-leading order (NNLO) low-energy constants \(L_i^r\) and \(C_i^r\) in chiral perturbation theory is obtained. These values are computed using the new experimental data with a new calculation method. This method combines the traditio...
