چکیده
Relativistic mean field study of the newly discovered α-decay chain of Abstract The single particle structure of the low lying levels in the nuclei belonging to the newly observed α-decay chain starting from 287 115 has been studied. Relativistic mean field calculation with two forces NL1 and NL3 has been performed in the blocked BCS approximation. Q-values for possible decay have been calculated and compared with experiment. Lifetime estimates obtained from phenomenological relations have also been compared.

The global properties of static perfect-fluid cylinders and their external Levi-Civita fields are studied both analytically and numerically. The existence and uniqueness of global solutions is demonstrated for a fairly general equation of state of the fluid. In the case of a fluid admitting a non-vanishing density for zero pressure, it is shown that the cylinder's radius has to be finite. For i...

We calculate the medium modifications of the ρππ vertex in a relativistic hadronic framework incorporating nucleons and ∆(1232) isobars, and find a substantial increase of the ρππ coupling, dominated by processes where the ∆ is excited. The coupling depends significantly on the virtuality of the ρ, which is related to analytic properties of the vertex function. We analyze the general case of a ...

We present bound state masses of the self-conjugate and non-self-conjugate mesons in the context of the Schrödinger equation taking into account the relativistic kinematics and the quark spins. We apply the usual interaction by adding the spin dependent correction. The pseudoscalar and vector decay constants of the Bc meson and the unperturbed radial wave function at the origin are also calcula...

We study the fragmentation of the b quark in top decay in NLO QCD, within the framework of perturbative fragmentation, which allows one to resum large logarithms ∼ log(m 2 t /m 2 b). We show the b-energy distribution, which we compare with the exact O(α S) result for a massive b quark. We use data from e + e − machines in order to describe the b-quark hadronization and make predictions for the ...

The semilinear wave equation on the (outer) Schwarzschild manifold is studied. We prove local decay estimates for general (non-radial) data, deriving a-priori Morawetz type inequalities.
