We consider an inflationary model in the hidden-sector broken supergravity with an effectively large cutoff. The inflaton decay into right-handed neutrinos naturally causes the observed baryon asymmetry of the universe with a reheating temperature low enough to avoid the gravitino overproduction. We emphasize that all the phenomenological requirements from cosmology and particle physics are sat...

We consider the issue of determining the D0-D̄0 width difference ∆ΓD experimentally. The current situation is reviewed and suggestions for further study are given. We propose a number of D0 decay modes in addition to those studied in the recent E791, FOCUS and BELLE lifetime determination experiments. Then we address prospects for determining CF CDS strong phase differences, like δKπ which appea...

The Alpha Magnetic Spectrometer (AMS-02) is a high energy particle physics experiment that will study cosmic rays in the ∼ 100 MeV to 1 TeV range and will be installed on the International Space Station (ISS) for at least 3 years. A first version of AMS-02, AMS-01, flew aboard the space shuttle Discovery from June 2 to June 12, 1998, and collected 10 8 cosmic ray triggers. Part of the Mir space...

The D+ → ωπ+ decay is studied by decomposing its amplitude into a sum of factorizable and non-factorizable ones. Its rate is predicted as a function of mass and width of a hypothetical hybrid meson. PACS number(s): 13.25.Ft, 11.30.Hv, 11.40.Ha, 12.39.Mk Typeset using REVTEX
