Standard Model and New Physics contributions to KL and KS into four leptons
We study the KL and KS decays into four leptons (eēeē, μμ̄μμ̄, eēμμ̄) where we use a form factor motivated by vector meson dominance, and show the dependence of the branching ratios and spectra from the slopes. A precise determination of short distance contribution to KL → μμ is affected by our ignorance on the sign of the amplitude A(KL → γγ) but we show a possibility to measure the sign of this ...
متن کاملK → πνν̄ from standard to new physics
Flavour changing neutral current decays are a very sensitive test of the standard model and its extensions. In particular the decay K → πνν̄ constitutes a clean way to provide constraints, independent of long distance effects. Motivated by the recent experimental data of the E787 and E865 collaborations and by the difference between the standard model prediction and data, we consider in detail n...
متن کاملExclusive B → K∗l+l− decay with polarized K∗ and new physics effects
Using the most general, model independent effective Hamiltonian, the branching ratio of the B → Kll decay, when K meson is longitudinally or transversally polarized, is presented. The dependence of the branching ratio on the new Wilson coefficients, when K meson is polarized, is studied. It is observed that the branching ratio is very sensitive to the vector and tensor type interactions, which ...
متن کاملRARE K DECAYS AND NEW PHYSICS BEYOND THE STANDARD MODEL a
Rare decays provide a complementary window to direct collider searches as probes of physics beyond the Standard Model. We present an overview of the New Physics sensitivity provided by existing and future measurements of rare leptonic and semileptonic K decays within the context of several classes of models.
متن کاملIs observed direct CP violation in B d → K + π − due to new physics ? Check standard model prediction of equal violation in B s → K − π +
The recently observed direct CP violation in Bd → K + π − has raised suggestions of possible new physics. A robust test of the standard model vs. new physics is its prediction of equal direct CP violation in Bs → K − π + decay. CPT invariance requires the observed CP violation to arise from the interference between the dominant penguin amplitude and another amplitude with a different weak phase...
