Priority:

Status:

In-progress

Physics of Light Mesons

Leader:

A.V. Kulikov

Participating Countries, Institutes and International organizations:
Azerbaijan, Belarus, Bulgaria, Croatia, Canada, Georgia, Germany, Italy, Poland, Romania, Russia, Switzerland, USA, Uzbekistan.

Scientific Programme:
Investigation of strong, weak and electromagnetic interactions of elementary particles and light nuclei at intermediate energies with the aim of determining symmetries and dynamics of the interactions. Development and construction of setups for experiments at accelerators (JINR phasotron, PSI meson factory, COSY proton synchrotron) for obtaining new information and testing the present theoretical views in the topics. Development of projects for new experiments and experimental methods for intermediate-energy physics.

Expected main results in 2011:

Finalizing of the data analysis for the reaction pd (pp)_s n and pp (pp)_s measured with the ANKE setup. Publication of results. Preliminary analysis of the process }d (pp)_s p measured with a polarized beam.
Measurement of the deuteron radiactive capture rate in muonic deuterium and analysis of the experimental results.
Determination of branching ratios for reaction channels of positive and negative pion interactions with the helium nucleus at incident pion energies 68 MeV, including the reaction channel with emission of a photon and the channel with -isobar production, further processing of the data (CCD images of reaction events), further estimation of the muon neutrino mass from - decay events; performing runs at the LNP phasotron. Publication of results.
Data taking at the accelerators of JINR and PSI meson factory (Switzerland). Study of the influence of the impurities on the acceptor parameters in the diamond-like and wide-gap semiconductors. Study of the properties of superparamagnetic nanoparticles in a non-magnetic matrix.
Data taking in measurement decay of the µ ⁺ e ⁺ (MEG). Processing of the experimental data.
