Charmed and Strange Quarks in Hadronic Reactions
(OSCAR)

Leader:	V.D. Kekelidze
Deputy:	Yu.K. Potrebenikov

Scientific Programme:
Experiments NA48 and OKAPI at CERN is purposed to obtain the most precise data on the CP-violation processor and rare kaon decays. The experiment is continued for a high sensitivity study of K_s and neutral hyperon decays using a modified K_s beam, and precision measurement of charged kaon decay parameters with the upgraded NA48 setup and new K12 beam line.
Experiment H1 is purposed to study processes of deep-inelastic ep-scattering in a wide kinematic range up to very high Q ² and down to very low Bjorken x to test QCD and electroweak sectors of the Standard Model.

Expected main results in 2007:

New experimental data will be processed and analysed.
New results on kaon and hyperon rare decays as well as on the measurement of CP-violating asymmetry in K3 decays will be obtained, on the base of data accunulated in 1999-2004 runs.
New organization principles will be developed and programmes for simulation and data analyses will be constructed.
A test run at the CERN SPS will be carried out.
Preparation of new proposal to study kaon rare decays at CERN SPS and carrying out of works to construct a straw-tube detector prototype for this experiment.
New BPC chamber, PLUG detector and FPS spectometer will be maintained.
Development of reconstruction programmes for BPC, PLUG and FPS-detectors.
Diffractive structure function F₂ ^D(3) will be measured in DIS processes with a leading proton in the final state.
Measurement of the diffractive inclusive cross section of photo-production and get photo-production hadrons with high transverse momentum.
