Theoretical review of K physics
We review several aspects of K-Physics: i) Main targets of the field, ii) The theoretical framework for K-decays, iii) Standard analysis of the unitarity triangle, iv) ε ′ /ε, v) Rare and CP violating K-decays, vi) Comparision of the potentials of K → πν ¯ ν and CP-B asymmetries. vii) Some aspects of the physics beyond the Standard Model.
