{'sha1': 'a9ea5ba626c995f590802d3e367440a06ff9bce6', 'content': 'A new set of the next-to-leading order (NLO) and the next-to-next-to-leading\norder (NNLO) low-energy constants L_i^r and C_i^r in chiral perturbation\ntheory is obtained. These values are computed using the new experimental data\nwith a new calculation method. This method combines the traditional global fit\nand Monte Carlo method together. The higher order contributions are estimated\nwith this method. The theoretical values of the observables provide good\nconvergence at each chiral dimension, except for the NNLO values of the π K\nscattering lengths a_0^3/2 and a_0^1/2. The fitted values for L_i^r\nat NLO are close to their results with the new method at NNLO; i.e., these\nL_i^r are nearly order-independent in this method. The estimated ranges for\nC_i^r are consistent with those in the literature, and their possible upper\nor/and lower boundaries are given. The values of some linear combinations of\nC_i^r are also given, and they are more reliable. If one knows a more exact\nvalue C_i^r, another C_i^r can be obtained by these values.', 'mimetype': 'text/plain', 'lang': 'en'}
