In the last few years, concepts and methodologies initially developed in physics have found high applicability in many different areas. This book, a result of cross-disciplinary interaction among physicists, biologists and physicians, covers several

AdS/QCD correspondence predicts the structure of quark-antiquark potential in the static limit. We use this piece of information together with the Salpeter equation (Schr\"odinger equation with relativistic kinematics) and a short range hyperfine spl

The large branching ratio for B → K 1 γ recently measured at Belle implies a large B → K 1 transition form factor and large branching ratios for non-leptonic B decays involving an axial-vector meson. In this Letter we present an analysis of two-

We show that a general purpose clusterization algorithm, Deterministic Annealing, can be adapted to the problem of jet identification in particle production by high energy collisions. In particular we consider the problem of jet searching in events g

We argue that in the color-flavor-locking (CFL) superconducting phase classical soliton solutions can exist, whose excitations should be interpreted as states formed by a quark (or an antiquark) and condensed diquarks. This finding extends the pictur

We compute, at the first order in the fine structure constant, the parameters of the electromagnetic Lagrangian for the inhomogeneous Larkin-Ovchinnikov-Fulde-Ferrell phase in Quantum Chromodynamics (QCD) and in condensed matter. In particular we com

We perform a comparison of two jet clusterization algorithms. The first one is the standard Durham algorithm and the second one is a global optimization scheme, Deterministic Annealing, often used in clusterization problems, and adapted to the proble

We describe the effective lagrangian approach to the color superconductivity. The effective description that arises if one considers only the leading terms in the expansion for very high densities is particularly simple. It is based on a lagrangian w

We examine the Ds→f0(980)π amplitude through a constituent quark–meson model, incorporating heavy quark and chiral symmetries, finding a good agreement with the recent E791 data analysis of Ds→3π via f0(980). The f0(980) resonance is consider

The properties of macroscopic chaos displayed by diluted neural networks with continuous neurons and nonmonotonic transfer function is analyzed, with both fixed and dynamic synapses. The responce to external noisy stimuli is also considered: a proper
