The COoler SYnchrotron COSY at the Forschungzentrum Juelich accelerates
protons and deuterons with momenta up to 3.7 GeV/c. COSY is the machine
for hadron spin physics on a world-wide scale. In combination with internal
polarized Hydrogen and Deuterium targets, the availability of electron and
stochastically cooled polarized proton and deuteron beams allows for precision
measurements....

Plenary Invited
The KLOE experiment has collected 2.5 fb-1 at the peak of the phi resonance at the e+e- collider DAPHNE in Frascati. The whole data set includes 100 million eta's produced through the radiative decay phi --> eta gamma and tagged by means of the monochromatic recoil photon. Measurements of eta decay channels, such as pi+ pi- gamma, are in progress. We have also measured the branching ratio of...

Plenary Contribution
Very little is known experimentally on proton-proton elastic scattering in the energy range from 1.6 to 2.8 GeV for centre-of-mass angles between about 10 and 30 degrees. The differential cross section data that do exist seem to fall systematically below the predictions of the SAID data analysis program. Measurements in this kinematical region are possible at the ANKE spectrometer, which is...

Plenary Contribution
Deuteron charge exchange break-up dp->{pp}n, where the final {pp} diproton system is at very low excitation energy and hence in the 1S_0 state, is a powerful tool to probe the spin-flip terms in the proton-neutron charge-exchange reaction. Recent measurements with the ANKE spectrometer at the COSY storage ring at 1.6, 1.8, and 2.3 GeV have extended this study into the pion-production regime in...

Plenary Contribution
An experimental program to study near threshold pion production in the
reactions pp->{pp}_s \pi^0 and pn->{pp}_s \pi^-, is undertaken at
ANKE-COSY. The selection of the final proton pair {pp}_s in the 1S0 state,
realized by cutting on the pair excitation energy E_{pp}<3 MeV, simplifies
the theoretical analysis of the processes. The combined study of these
reactions is motivated by the...

Hadron Physics
Plenary Contribution
The Kbar-N system at rest makes a sensitive testing ground for the understanding of strong interaction at low energies. At the DAFNE electron-positron collider of Laboratori Nazionali di Frascati we study X-ray transitions of kaonic atoms, taking advantage of the low-energy kaons produced by Phi-mesons decaying nearly at rest. In the SIDDHARTA (Silicon Drift Detector for Hadronic Atom...

Hadron Physics
Plenary Contribution
The decay of the π 0 meson into an electron–positron pair is heavily sup-
pressed in the Standard Model (SM) with an expected branching ratio of
6 × 108 . The decay is therefore sensitive to contributions from physics be-
yond the SM. Recently, the KTeV collaboration at Fermilab has performed
a precise measurement of the π 0 → e+ e− decay branching ratio using a data
sample of 800 events....
