Unstable particle mixing and CP violation in weak decays.
نویسندگان
چکیده
We discuss unstable particle mixing in CP-violating weak decays. It is shown that for a completely degenerate system unstable particle mixing does not introduce a CP-violating partial rate difference, and that when the mixings are small only the off-diagonal mixings are relevant. Also, in the absence of mixing, unstable particle wave function renormalization does not introduce any additional effect. An illustrative example is given to heavy scalar decays with arbitrary mixing.

We review the highlights of quark mixing, particle–antiparticle mixing, CP violation and rare Kand B-decays in the Standard Model. The top quark discovery, the precise measurement of its mass, the improved knowledge of the couplings Vcb and Vub, and the calculations of NLO short distance QCD corrections improved considerably the predictions for various decay rates, the determination of the coup...

The phenomenon of CP violation is one of the most intriguing aspects of modern physics, with far-reaching implications for the microscopic world as well as for the macrocosmos. CP violation means that there is a fundamental difference between the interactions of matter and anti-matter, which in conjunction with the CPT theorem implies a microscopic violation of time-reversal invariance. CP viol...
