Using untagged B 0 → DK S to determine γ
نویسندگان
چکیده
It is shown that the weak phase γ ≡ arg(−VudV ∗ ubVcbV ∗ cd) can be determined using only untagged decays B0/B̄0 → DKS. In order to reduce the uncertainty in γ, we suggest combining information from B → DK and from untagged B0 decays, where the D meson is observed in common decay modes. Theoretical assumptions, which may further reduce the statistical error, are also discussed. Work supported in part by the Department of Energy contract DE-AC03-76SF00515.

New Strategies to Obtain Insights into Cp Violation Through
Decays of the kind B s → D ± us to probe φ s + γ and φ d + γ, respectively, involving the angle γ of the unitarity triangle and the B 0 q –B 0 q mixing phases φ q (q ∈ {d, s}). Analysing these modes in a phase-convention-independent way, we find that their mixing-induced observables are affected by a subtle (−1) L factor, where L denotes the angular momentum of the B q decay products, and deriv...
متن کاملMixing , CP Violation and Extraction of CKM Phases from Untagged B s Data Samples
A width difference of the order of 20% has previously been predicted for the two mass eigenstates of the B s meson. The dominant contributor to the width difference is the b → c¯ cs transition, with final states common to both B s and B s. All current experimental analyses fit the time-dependences of flavor-specific B s-modes to a single exponential, which essentially determines the average B s...
متن کاملA new method for extracting the weak phase γ from B →
A new method to extract the weak phase γ is suggested by exploiting B → DK(∗) decay modes that are not Cabibbo suppressed, using the isospin relations, and ignoring the annihilation diagram as usual. Assuming 3× 108BB̄ pair at B factories, one can determine γ with 3− σ accuracy for 80 ∼ γ ∼ 150 using B → DK modes and for 50 ∼ γ ∼ 170 using B → DK∗ modes. ∗e-mail : [email protected] †e-mai...
متن کاملImproving Bounds on Γ in B ± → Dk ± and B ±,0 → Dx ±,0
In view of recent experimental progress in rate and CP asymmetry measurements in B → DK, we reconsider information on the weak phase γ which can be obtained from these processes. Model-independent inequalities are proven for sin γ in terms of two ratios of partial rates for B → DX s , where Xs is any multiparticle charmless state carrying strangeness ±1. Good prospects are shown to exist for us...
متن کاملCP violation and CKM phases from angular distributions for Bs decays into admixtures of CP eigenstates
We investigate the time-evolutions of angular distributions for Bs decays into final states that are admixtures of CP-even and CP-odd configurations. A sizable lifetime difference between the Bs mass eigenstates allows a probe of CP violation in time-dependent untagged angular distributions. Interference effects between different final state configurations of Bs → D s D s , J/ψ φ determine the ...
