Double–lepton polarization asymmetries in Λb → Λl+l− decay
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...
متن کاملA $2\ell k$ Kernel for $\ell$-Component Order Connectivity
In the `-Component Order Connectivity problem (` ∈ N), we are given a graph G on n vertices, m edges and a non-negative integer k and asks whether there exists a set of vertices S ⊆ V (G) such that |S| ≤ k and the size of the largest connected component in G−S is at most `. In this paper, we give a kernel for `-Component Order Connectivity with at most 2`k vertices that takes nO(`) time for eve...
متن کاملDouble–lepton polarization asymmetries in Λb → Λl+l− decay in universal extra dimension model
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 کاملDouble–lepton polarization asymmetries in the B → Kl+l− decay beyond the Standard Model
General expressions for the double–lepton polarizations in the B → Kl+l− decay are obtained, using model independent effective Hamiltonian, including all possible interactions. Correlations between the averaged double–lepton polarization asymmetries and the branching ratio, as well as, the averaged single–lepton polarization asymmetry are studied. It is observed that, study of the double–lepton...
متن کاملDouble–lepton polarization asymmetries in the Exclusive B → ρl+l− decay beyond the Standard Model
The double–lepton polarization asymmetries in B → ρl+l− decay is analyzed in a model independent framework. The general expressions for nine double–polarization asymmetries are calculated. It is shown that the study of the double–lepton polarization asymmetries proves to be very useful tool in looking for new physics beyond the standard model.
