Polarized forward – backward asymmetries of leptons in B s → l + l − γ decay
Polarized forward–backward asymmetries in the Bs → l+l−γ decay are calculated using the most general, model independent form of the effective Hamiltonian, including all possible forms of interactions. The dependencies of the asymmetries on new Wilson coefficients are investigated. The detectability of the asymmetries at LHC is discussed.

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 کاملPolarized lepton pair forward–backward asymmetries in B → K∗l+l− decay beyond the standard model
We study the polarized lepton pair forward–backward asymmetries inB → K∗l+l− decay using the most general, model independent form of the effective Hamiltonian. We present the general expression for nine double–polarization forward–backward asymmetries. It is shown that, the study of the forward–backward asymmetries of the doubly–polarized lepton pair is a very useful tool for establishing new p...

The polarized lepton pair forward–backward asymmetries in B → ρl+l− decay using a general, model independent form of the effective Hamiltonian is studied. The general expression for nine double–polarization forward–backward asymmetries are calculated. The study of the forward–backward asymmetries of the doubly–polarized lepton pair proves to be very useful tool in looking for new physics beyond...
متن کاملRethinking $(k,\ell)$-anonymity in social graphs: $(k,\ell)$-adjacency anonymity and $(k,\ell)$-(adjacency) anonymous transformations
This paper treats the privacy-preserving publication of social graphs in the presence of active adversaries, that is, adversaries with the ability to introduce sybil nodes in the graph prior to publication and leverage them to create unique fingerprints for a set of victim nodes and re-identify them after publication. Stemming from the notion of (k, l)-anonymity, we introduce (k, l)-anonymous t...
