Experimental Tests of Discrete Symmetries with Kaons and B-mesons
B. Peyaud
During the last decades, experiments using K mesons have provided precise measurements of CP 
violation parameters which are important inputs for the understanding of flavour physics. 
They include the measurements of Re(epsilon/epsilon) by NA48 and KTeV experiments using $K_L$ and $K_S$, the 
search for CP violation in $K^{}$ -> 3pi decays and rare decay processes allowing to search for new
 physics and to test chiral perturbation theory. Moreover, NA62, a new experiment at the CERN/SPS,
 will measure the branching ratio of K+ -> pi+ nu nubar to test further the Standard Model. Experimental 
efforts in the kaon sector will thus continue for some time. Alternatively, in the B-meson system,
 there are more decay modes available, and the Standard Model makes precise predictions for CP 
violation in a number of these. The B-meson system is therefore a very attractive area to study 
CP violation and to search for new physics. The LHCb experiment at the Large Hadron Collider (LHC)
 and its prospects in the study of CP violation in the B-meson sector are discussed.
