Phenomenological methods for unitarity triangle angles
The Kobayashi-Maskawa model for CP violation [1] passed in a remarkable way its first crucial test in B decays [2] when a large CP asymmetry was measured [3, 4] in B → J/ψKS in agreement with expectations. The virtue of this gold-plated decay mode is the absence of hadronic uncertainties [5, 6] in predicting the mixing induced asymmetry in terms of a fundamental phase parameter β ≡ φ1 of the St...
متن کاملThe Matrix of Unitarity Triangle Angles for Quarks
In the context of quark (as for lepton) mixing, we introduce the concept of the matrix of unitarity triangle angles Φ, emphasising that it carries equivalent information to the complex mixing matrix V itself. The angle matrix Φ has the added advantage, with respect to V , of being both basisand phase-convention independent and consequently observable (indeed several Φ-matrix entries, eg. Φcs = ...
متن کاملAngles of the Ckm Unitarity Triangle Measured at Belle
The Belle experiment has used several methods to measure or constrain the angles φ 1 , φ 2 , and φ 3 (or β, α, and γ) of the CKM unitarity triangle.
متن کاملPredictions for the unitarity triangle angles in a new parametrization
A new approach to the parametrization of the CKM matrix, V , is considered in which V is written as a linear combination of the unit matrix I and a non-diagonal matrix U which causes intergenerationalmixing, that is V = cos θ I + i sin θ U . Such a V depends on 3 real parameters including the parameter θ. It is interesting that a value of θ = π/4 is required to fit the available data on the CKM...
متن کاملIndirect Determination of the Vertex and Angles of the Unitarity Triangle
The values of the elements of the Cabibbo-Kobayashi-Maskawa matrix are constrained by direct and indirect measurements. A fit to experimental data and theory calculations allows the indirect determination of the vertex and angles of the unitarity triangle as:
