Abstract
Two years after the launch and begin of operation of AMS on the ISS, precision measurements of
cosmic rays composition and spectra are presented. We also discuss the experience gained
operating for the first time and for a long time a large particle physics experiment on the ISS.

In four-dimensional gravity theories with local supersymmetry, electric-magnetic duality rotations play a significant role, especially through the symplectic matrix M, related to the coupling of scalar fields to Abelian 2-form field-strengths.
I will give a basic introduction on some aspects of supergravity theories, focusing on the class of duality groups "of type E7", and on the...

Form factors provide some of the most direct insight into the structure of hadrons. For mesons and hyperons, none of which are available as targets, form factor measurements can only be made for timelike momentum transfers by means of e+e- -> hhbar reactions, where h can be any hadron. Further, only for large momentum transfers the measurements can be hopefully understood in terms of QCD, or...

The recent PSI Lamb shift experiment has displayed a disagreement of 7sigmas between the experimental values of the proton r.m.s. charge radius extracted from e-p scattering and muonic hydrogen spectroscopy. This discrepancy has not yet been explained; it is not even known whether it may be ascribed to the different experimental methods or reflects some fundamental features of the muon. The...

Abstract: The production of a polarized solid HD represents a technical challenge that by now can be considered solved. The actual frontier is the implementation of such a target in a Deep Inelastic Scattering experiment. An intensive program is presently underway at Jefferson Lab (Virgina, USA) to explore the possible effects of the interaction of an electron beam with the target material....

"The quest of Dark Matter signals in the gamma-ray sky is one of the most intriguing and exciting challenges in astrophysics.
The analysis of the gamma-ray photons collected by the Fermi Large Area Telescope reveals the existence of an excess towards the Galactic center compatible with Dark Matter annihilation.
We review and discuss the recent literature about this subject."

Abstract: The description of the decay law and its link to the energy
distribution is shown in quantum mechanics (QM). Deviations from the
exponential decay law exist at short and long times; experiments are
discussed, in which these deviations have been seen. A related effect is
the so-called Quantum Zeno effect, which forbids the decay (or a
transition) of a quantum state that is...
