Chiral dynamics in the meson sector at two loops

Author

  • Johan Bijnens

Summary, in English

I give a very short introduction to chiral perturbation theory and an overview of the next-to-next-to-leading order three-flavour calculations done. I discuss those relevant for an improvement in the accuracy of the measurement of V<sub>us</sub> in more detail. One major conclusion is that all needed p<sup>6</sup> low energy constants can be obtained from experiment via the scalar form-factor in K<sub>l3</sub> decays
