Matrix elements of four-quark operators relevant to life time difference \(\Delta \Gamma _{B_s}\) from QCD sum rules
We extract the matrix elements of four-quark operators \(O_{L,S}\) relevant to the \(B_s\) and \({\bar B}_s\)

CP violation and extra dimensions
It is shown that new sources of CP violation can be generated in models with more than one extra dimension. In the supersymmetric models on the space-time \(M^4\times T^2/Z_2\) ,...

Rare decay \(B\rightarrow X_sl^+l^-\) in a CP spontaneously broken two-Higgs doublet model
The Higgs boson mass spectrum and couplings of the neutral Higgs bosons to the fermions are worked out in a CP spontaneously broken two-Higgs doublet model in the large \(\tan\beta\) ...

Dependence of synchronization transitions on mean field approach in two-way coupled neural system
This work investigates the synchronization transitions in two-way coupled neural system by mean field approach. Results show that, there exists a critical noise intensity for the synchronization transitions, i...
