New Physics and CP Angles Measurement
نویسنده
چکیده
We have analyzed how much the CP angles to be measured at B factories can deviate from the geometrical ones de ned in unitarity triangle under the existence of new physics. The measurements are given in rephasing invariant form. If KM matrix is not a 3 3 and unitary matrix, ~ 1 and ~ 3 is a ected, and the value of ~ 3 depends on the decay mode. The deviation is constrained to be less than the experimental precision attained in the next decade by the available data of the magnitude of KM matrix elements. Deviation of the sum of three angles from cannot be detected unless new physics contributes signi cantly to b decay or D meson system. e-mail: [email protected] present address: Aishin Seiki Jinta-ryo, Maebayashi, Toyota, Aichi 473, Japan.

New Physics and CP Angles Measurement at B Factory
We have analyzed how much the CP angles to be measured at B factories can deviate from the geometrical ones defined in unitarity triangle under the existence of new physics. The measurements are given in rephasing invariant form. If KM matrix is not a 3×3 and unitary matrix, φ̃1 and φ̃3 is affected, and the value of φ̃3 depends on the decay mode. The deviation is constrained to be less than the ex...
متن کاملMeasurement of the CKM Angles at BaBar and Belle
The primary goal of the BaBar and Belle experiments is to overconstrain the CKM Unitarity Triangle. Measurements of the angles of this triangle, known as β, α, and γ (or φ1, φ2, and φ3) give insight into the Standard Model description of CP violation in the quark sector. BaBar and Belle have recorded almost 1 ab−1 combined, and have measured β to high precision. Measurements of α and γ are less...
متن کاملCP Violation Studies in ATLAS and CMSNorbert NeumeisterInstitute
The large number of b b events at LHC will ooer the possibility to study CP violation in the B system. The two general purpose detectors ATLAS and CMS, primarily designed to study high p t-phenomena, are capable of doing B-physics and the possibility of measuring CP has been investigated by both collaborations. We discuss the potential of the two detectors for the measurement the angles alpha a...
متن کاملPhysics at the B Factories
We review recent progress at the two e + e − B factories. The first measurement of CP violation and the prospects for measuring all the angles of the unitarity triangle are discussed.
متن کاملPenguins and Mixing Dependent CP Violation
Constraints on angles of Unitarity triangle are reviewed, and in particular constraint on γ from limit on ∆m s is emphasized. Effects of penguin diagram on measurement of β and α are then reviewed. New measurements on B → π + π − in QCD improved factorization approximation suggest large penguin effects. It is possible to estimate the error in measurement of α as a function of γ for different |V...
