Angular analysis of the decay Λ b → Λ ( → Nπ ) ` + ` −
We study the differential decay rate for the rare Λb → Λ(→ Nπ)`+`− transition, including a determination of the complete angular distribution, assuming unpolarized Λb baryons. On the basis of a properly chosen parametrization of the various helicity amplitudes, we provide expressions for the angular observables within the Standard Model and a subset of new physics models with chirality-flipped ...
متن کاملSpectral distribution for the decay τ → ν τ Kπ
With the newly available data sets on hadronic τ decays from theB-factories BABAR and BELLE, and future data from BESIII, precise information on the decay distributions will soon become available. This calls for an improvement of the decay spectra also on the theoretical side. In this work, the distribution function for the decay τ → ντKπ will be presented with the relevantKπ vector and scalar ...
متن کاملENHANCEMENT OF THE Λb DECAY RATE 1
The enhancement ∆Γ(Λb) of the Λb decay rate due to four-fermion processes of weak scattering and Pauli interference is calculated within the quark model. An estimate of the relative bu wave function at zero separation, |Ψ(0)|bu, is obtained in terms of the Σ ∗ b − Σb hyperfine splitting, the B∗ − B hyperfine splitting, and the B meson decay constant fB. For M(Σ∗b)−M(Σb) = 56±16 MeV,M(B ∗)−M(B) ...
متن کاملNew Possibility of Solving the Problem of Lifetime Ratio τ(Λb)/τ(Bd)
We discuss the problem of the large discrepancy between the observed lifetime ratio of Λb to Bd and the theoretical prediction obtained by the heavy quark effective theory. A new possibility of solving this problem is proposed from the viewpoint of operator product expansion and the lifetime ratio of Ωb to Bd is predicted. The heavy quark effective theory (HQET) is successful in explaining vari...
متن کاملOn the CVC problem in τ-decay
The preliminary results of PIBETA experiment strongly suggest the presence of non V −A anomalous interactions in the radiative pion decay. We assume that they arise as a result of the exchange of new intermediate chiral spin-1 bosons which interact anomalously with matter. Their contribution into the τ -decay leads to violation of the CVC hypothesis at the same level as detected experimentally....
