in this research we work with the effective hamiltonian and the quark model. we investigate the decay rates of matter-antimatter of quark. we describe the effective hamiltonian theory and apply this theory to the calculation of current-current ( ), qcd penguin ( ), magnetic dipole ( ) and electroweak penguin ( ) decay rates. the gluonic penguin structure of hadronic decays is studied through th...

The knowledge about quantum effects on guiding center motion is important for low-temperature experiments with charged particles in external electromagnetic fields. In this paper we explicitly determine the quantum mechanical corrections to the classical guiding center Hamiltonian using a gauge invariant version of the Weyl calculus. We derive a product rule for gauge invariant Weyl symbols whi...

a graph that contains a hamiltonian cycle is called a hamiltonian graph. in this paper wecompute the first and the second geometric – arithmetic indices of hamiltonian graphs. thenwe apply our results to obtain some bounds for fullerene.

DCell has been proposed for data centers as a server centric interconnection network structure. DCell can support millions of servers with high network capacity by only using commodity switches. With one exception, we prove that a k level DCell built with n port switches is Hamiltonian-connected for k ≥ 0 and n ≥ 2. Our proof extends to all generalized DCell connection rules for n ≥ 3. Then, we...

Let G be a connected reductive group over an algebraically closed field K of characteristic 0, X an affine symplectic variety equipped with a Hamiltonian action of G. Further, let ∗ be a G-invariant Fedosov star-product on X such that the Hamiltonian action is quantized. We establish an isomorphism between the center of the quantum algebra K[X ][[~]] and the algebra of formal power series with ...

The Hamiltonian structure of the guiding-center Vlasov-Maxwell equations is presented in terms a functional and bracket. bracket, which shown to satisfy Jacobi identity exactly, used show that momentum angular-momentum conservation laws can also be expressed form.

We calculate the charge form factor and the longitudinal structure function for 16O and compare with the available experimental data, up to a momentum transfer of 4 fm(-1). The ground-state correlations are generated using the coupled-cluster [ exp(S)] method, together with the realistic v18 NN interaction and the Urbana IX three-nucleon interaction. Center-of-mass corrections are dealt with by...
