Book Description
If CP is violated in any decay process involving leptons it will signify the existence of a new force (called the X boson) responsible for CP violation that may be the key to understanding matter-antimatter asymmetry in the universe. The author discusses the signatures of CP violation in (1) the decay of tau lepton, and (2) the semileptonic decay of [pi], K, D, B and t particles by measuring the polarization of the charged lepton in the decay. The author discusses how the coupling constants and their phases of the coupling of the X boson to 9 quark vertices and 3 lepton vertices can be obtained through 12 decay processes.

Book Description
We report a search for CP violation in the decay?− →?−K{sub S}°({>=} 0?°)?{sub?} using a dataset of 437 million {tau} lepton pairs, corresponding to an integrated luminosity of 476 fb−1, collected with the BABAR detector at the PEP-II asymmetric energy ee− storage rings. The CP-violating decay-rate asymmetry is determined to be ( -0.45 ± 0.24 ± 0.11)%, approximately three standard deviations from the Standard Model prediction of (0.33 ± 0.01)%.

Book Description
In the Standard Model no CP violation can occur in decay processes involving leptons either as a parent or a daughter because these processes involve one W exchange and thus, even if the CP violating complex coupling exists in these decays, its effect will not show up when the amplitude is squared. The author needs two diagrams to interfere with each other to see the CP violating effects. Here, he discusses ways to find CP violation in the decay of [tau]{sup {+-}} → [nu]{sub [tau]} + 3[pi] from unpolarized as well as polarized {tau}{sup {+-}}.

Book Description
If CP is violated in any decay process involving leptons it will signify the existence of a new scalar boson (called the X boson) responsible for CP violation that may be the key to understanding matter-antimatter asymmetry in the universe. The authors discuss the signatures of CP violation in (1) the decay of tau and mu leptons, and (2) the semileptonic decay of[pi], K, D, B and t particles by measuring the polarization of the charged lepton in the decay. The authors discuss how the coupling constants and their phases of the coupling of the X boson to 9 quark vertices and 3 lepton vertices can be obtained through 12 decay processes.
