It is shown that partition functions of different S dual theories of N=2 SU(2) gauge theory with four fundamentals can be derived from the crossing symmetry... Dimitri V.

Our results show that accretion onto compact objects with Kerr parameter (characterizing the spin) |a| < M and |a| > M is very different. In the super-spinning case, for |a| moderately larger than M, the accreti...

Then we derive the higher-dimensional correction of the precession angle to the general relativity. We find that the corr...

The tree-level and one-loop contributions from vector field perturbations are worked out considering the possibility that the one-loop cont... Cesar A.

We analyze the exotic matter content, and find that for certain values of the Born-Infeld parameter the amount of exotic matter on the shell can be reduced in relation with the Maxwell case. W...

This result is achieved by the quintessential (phantom) potential determined by the existence of the symmetry itself. A comparison between the th... S. Capozziello, E. Piedipalumbo, C. Rubano and P.

We show how a system of second-quantized fermions influences the ground state of the whole system by producing a gap between the highest eigenval... I. Andric, L. Jonke, D. Jurman and H. B.

CP-violating couplings in charged leptonic currents carry out the weak phases necessary to break these symmetries. Here we study the interference of ... G. Lopez Castro, L. Lopez Lozano and A.

We first derive the equation of state for unparticles and use it to obtain the temperature dependence of the corresponding energy...

It is based on an observable inspired by astronomers' practice, namely the significance in the difference between corresponding Dalitz plot bins. It provides a model independent mapping of local...

Consistency with holomorphy requirements of supergravity and the Kaplunovsky-Louis formula implies that the unification scale is enhanced by the bulk radius R from the string scale to MX = RMS. We argue that the stringy inter... Joseph P.

We carry out this matching through O(v4) in the binary's orbital velo... Nathan K. Johnson McDaniel, Nicolas Yunes, Wolfgang Tichy and Benjamin J.

In this paper we discuss new contributions to the dijet imbalance that could complicate or even hamper this extraction. They are due to polarization of init... Daniel Boer, Piet J.

We find that, using the Anti-de Sitter-Black Hole metric for all values of the temperature, the masses of the hadronic states decrease and the widths become broader when T increases, and there are temperatures...

We demonstrate that the energy of a primary photon may be significantly (up to a factor of ~ 10) under- or overestimated for particular primary energies and... O. E. Kalashev, G. I. Rubtsov and S. V.
