Π-η Mixing from Qcd Sum Rules

The q2 dependence of the π-η mixing amplitude is examined with the use of QCD sum rules. The linear slope of the mixing function θ(q2) is found to be much smaller than that for ρ-ω mixing. Thus the mixing amplitude is approximately the same in the space-like region as in the time-like one, and one may neglect the q2 dependence of the mixing. A comparison between a hadron-meson, an effective chi...

Extracting CKM Phases and Bs–Bs Mixing Parameters from Angular Distributions of Non-Leptonic B Decays

Suggestions for efficiently determining the lifetimes and mass difference of the light and heavy Bs mesons (B L s , B H s ) from Bs → J/ψφ,D∗+ s D∗− s decays are given. Using appropriate weighting functions for the angular distributions of the decay products (moment analysis), one can extract (ΓH ,ΓL,∆m)Bs . Such a moment analysis allows the determination of the relative magnitudes and phases o...

Analyzing B s − B̄ s mixing : Non - perturbative contributions to bag parameters from sum rules

We use QCD sum rules to compute matrix elements of the ∆B = 2 operators appearing in the heavy-quark expansion of the width difference of the B s mass eigenstates. Our analysis includes the leading-order operators Q and Q S , as well as the subleading operators R 2 and R 3 , which appear at next-to-leading order in the 1/m b expansion. We conclude that the violation of the factorization approxi...

Neutrino Mixing Sum Rules and Oscillation Experiments

The neutrino mixing sum rule θ 12 − θ 13 cos(δ) ≈ θ ν 12 provides a possibility to explore the structure of the neutrino mass matrix in the presence of charged lepton corrections, since it relates the 1-2 mixing angle from the neutrino mass matrix, θ ν 12 , to observable parameters of the PMNS mixing matrix. The neutrino mixing sum rule holds if the charged lepton mixing angles are CKM-like, i....
