Λ hyperon as helicity analyzer of s quark in B decay
نویسنده
چکیده
We explore how well one can probe the s quark chirality of the fundamental weak interaction of nonleptonic B decay using the spin-analyzing property of the Λ hyperon. We present the prediction of the Standard Model as quantitatively as possible in a perturbative QCD picture avoiding detailed form-factor calculation involving quark mass corrections. A clean test of chirality will be possible with B → ΛX. PACS number(s): 13.25.Hw,13.30.Eg,14.20.Jn,12.15.-y Typeset using REVTEX

Helicity Amplitudes and Electromagnetic Decays of Strange Baryon Resonances
We present results for the helicity amplitudes of the lowest-lying hyperon resonances Y , computed within the framework of the Bonn constituent-quark model, which is based on the Bethe-Salpeter approach 1,2,3. The seven parameters entering the model are fitted against the best known baryon masses 4. Accordingly, the results for the helicity amplitudes are genuine predictions. Some hyperon reson...
متن کاملHelicity and Transversity Distributions of Nucleon and Λ - Hyperon from Λ Fragmentation
It is shown that Λ-hyperon fragmentation in charged lepton deep inelastic scattering (DIS) on a polarized nucleon target can provide sensitive information concerning the quark helicity and transversity distributions for both nucleon and Λ-hyperon at large x. Numerical predictions are given for the spin transfers of the produced Λ, when the target nucleon is polarized either longitudinally or tr...
متن کاملStrongly Distorted Baryon Wave–functions: Hyperon Beta–decay and the Spin of the Λ and the Nucleon∗)
Within the collective coordinate approach to chiral soliton models we suggest that breaking of SU(3) flavor symmetry mainly resides in the baryon wave–functions while the charge operators have no (or only small) symmetry breaking components. In this framework we study the gA/gV ratios for hyperon beta–decay as well as the various quark flavor components of the axial charge of the nucleon and th...

We present the recent investigation on the effect of the SU(3) symmetry breaking in the spin structure of the octet baryons. The spin structure of the nucleon has been a hot issue since the measurement of the first moment of the proton spin structure function g p 1 [1] by the European Muon Collaboration (EMC). The EMC result indicates that the strange quark is polarized in the opposite directio...

This research, works with the effective Hamiltonian and the quark model. Using, the decay rates of matter-antimatter of b quark was investigated. We described the effective Hamiltonian theory which was applied to the calculation of current-current (Q1,2), QCD penguin (Q3,…,6), magnetic dipole (Q8) and electroweak penguin (Q7,…,10) decay rates. The gluonic penguin structure of hadronic decays ...
