P–odd asymmetries in polarized Λb → Λl+l− decay
نویسنده
چکیده
We calculate various P–odd asymmetries appearing in the differential decay width for the cascade decay Λb → Λ(→ a+ b)V ∗(→ l+l−) with polarized and unpolarized heavy baryons including new vector type interactions and using the helicity amplitudes. It is obtained that the study of P–odd asymmetries can serve a good test for establishing new physics beyond the SM.

Forward–backward asymmetries in Λb → Λl+l− decay beyond the standard model
We study the doubly–polarized lepton pair forward–backward asymmetries in Λb → Λl+l− decay using a general, model independent form of the effective Hamiltonian. We present the general expression for nine double–polarization forward– backward asymmetries. It is observed that, the study of the forward–backward asymmetries of the doubly–polarized lepton pair is a very useful tool for establishing ...

Double–lepton polarization asymmetries in Λb → Λl+l− decay are calculated using a general, model independent form of the effective Hamiltonian. The sensitivities of these asymmetries to the new Wilson coefficients are studied in detail. Furthermore, the correlations between averaged double–lepton polarization asymmetry and branching ratio are analyzed. It is shown that there exist certain regio...

Double–lepton polarization asymmetries in Λb → Λl+l− decay are calculated in universal extra dimension (UED) model. It is obtained that numerous double–lepton polarization asymmetries are very sensitive to the UED model and therefore can be very useful tool for establishing new physics predicted by the UED model.

متن کاملNew physics effects in Λb → Λl+l− decay with lepton polarizations
We study lepton polarization asymmetries in the Λb → Λl+l− decay using the most general model independent effective Hamiltonian. The dependence of the lepton polarizations and their combinations on the new Wilson coefficients are studied in detail. It is observed that there is a region for the new Wilson coefficients for which the branching ratio coincides with the standard model prediction, wh...

The independent helicity amplitudes in the Λb → Λl+l− decay in the standard model and its minimal extension, i.e., with the new vector type interactions, are calculated. We calculate various asymmetry parameters characterizing the angular dependence of the differential decay width for the cascade decay Λb → Λ(→ a + b)V ∗(→ l+l−) with polarized and unpolarized heavy baryons. The sensitivity of t...
