Chiral perturbation theory beyond one loop

    Research output: Contribution to journalReview articlepeer-review

    Abstract

    The existing Chiral Perturbation Theory (ChPT) calculations at order p<sup>6</sup> are reviewed. The principles of ChPT and how they are used are introduced. The main part is a review of the two- and three-flavour full two-loop calculations and their comparison with experiment. We restrict the discussion to the mesonic purely strong and semileptonic sector. The review concludes by mentioning the existing results in finite volume, finite temperature and partially quenched ChPT
