CP Violation and Heavy Hadrons
I review several topics involving CP violation with heavy hadrons. In particular, I discuss (i) Hyperons: CP violation in the decay Λ → pπ, (ii) Charm: indirect CP violation in the D system, both within and beyond the SM, and (iii) Beauty: indirect CP violation in the neutral B-meson system beyond the SM.
متن کاملHeavy Flavours and CP violation
Recent results on Heavy Flavours and CP violation are presented. After a short introduction a taste of K and D results is given. In a third part results on |V td | and |V ts | are summaryzed including BB mixing results and B d radiative decays. A summary of |V cb | and |V ub | measurements is presented in the fourth part. In the next section CP violation measurements in the B d sector are shown...
متن کاملHeavy Quark Lifetimes, Mixing and CP Violation
This paper emphasizes four topics that represent some of the year’s highlights in heavy quark physics. First of all, a review is given of charm lifetime measurements and how they lead to better understanding of the mechanisms of charm decay. Secondly, the CLEO collaboration’s new search for charm mixing is reported, which significantly extends the search for new physics in that sector. Thirdly,...
متن کاملCp-violation in the Heavy Quark Systems
After the precision measurements of electroweak parameters at LEP, FNAL and SLAC, the main progress in the experimental study of Standard Model (SM) is connected to investigations in the Higgs sector. The Higgs mechanism provides the basic renormalization properties of the SM as well as the masses of vector gauge fields and fermions. There are two directions in these studies. The first is an ob...
متن کاملCP-Violation with Bosons
We formulate the conditions under which a purely bosonic theory (without fermions) containing neutral spin-0 particles and vector (gauge) bosons violates the CP-symmetry through the presence of CP-even and CP-odd operators in the Lagrangian. This is done without reference to explicitly CP-violating scalar sector of extended standard models (SM) with two or more Higgs doublets. The Lagrangian ex...
