نویسنده
چکیده
Propagation of initially localized perturbations is investigated in chaotic coupled map lattices with long-range couplings decaying as a power of the distance. The initial perturbation propagates exponentially fast along the lattice, with a rate given by the ratio of the maximal Lyapunov exponent and the power of the coupling. A complementary description in terms of a suitable comoving Lyapunov exponent is also given. PACS numbers: 05.45.+b Typeset using REVTEX

We consider the Minimal Gauge Mediated Model (MGMM) with either fundamental or antisymmetric messenger multiplets and study consequences of messenger-matter mixing. It is shown that constraints on relevant coupling constants and mixing parameters coming from the existing experimental limits on lepton flavor violation and FCNC processes allow a wide range of tan β in MGMM with mixing.

Models with extended quark sector affect the CP asymmetry in the B → ψKS decay, aψKS , in two ways: First, the top-mediated box diagram is not necessarily the only important contribution to B − B̄ mixing. Second, the 3 × 3 CKM matrix is no longer unitary. We analyze the constraints that follow from the CDF measurement, aψKS = 0.79 +0.41 −0.44, on the mixing parameters of extended quark sectors. ...

We find that perturbation theory fails to describe the short range static potential as obtained from quenched lattice simulations, at least for source separations r > (6 GeV)−1. The difference between the nonperturbatively determined potential and perturbation theory at short distance is well parameterised by a linear term with a slope of approximately 1 GeV2, that is significantly bigger than ...

We discuss the relevance of chaotic scattering in heavy–ion reactions at energies around the Coulomb barrier. A model in two and three dimensions which takes into account rotational degrees of freedom is discussed both classically and quantum-mechanically. The typical chaotic features found in this description of heavy-ion collisions are connected with the anomalous behaviour of several experim...

This paper is meant as a contribution to the often debated subject of how to combine data which appear to be in mutual disagreement. As a practical example, the ǫ ′ /ǫ determinations have been considered.
