About

We will discuss how the constraints on symmetries can be implemented in the calculation of particle properties. Using the notion of "effective field theories" we will show how symmetry can be used to parameterize in interactions of even very complicated systems in relatively simple ways. For examples we will discuss the pions and kaons of QCD and radiative corrections in the weak interactions. Topics to be covered: Symmetries and constraints on interactions - Low energy effective interactions - Mesons and chiral symmetry breaking - Weak interactions and radiative corrections.
