The structure effects in polarization and cross section in inelastic A(p,p')X reaction with the 40Ca and 12C nuclei at 1 GeV

The polarization of the secondary protons in inelastic (p,p') reaction on the 40Ca and 12C nuclei at the initial proton energy 1 GeV was measured in the wide range of the scattered proton momenta at a laboratory angle 21 degree. The cross section of the reactions were measured as well. The outgoing protons from the reaction were detected using a magnetic spectrometer equipped with a multiwire-proportional chambers polarimeter. A structure in the polarization and cross section data, related probably to scattering of the nucleon correlation in the nuclei, was observed.

Polarization effects in the quasi - elastic (p,2p) reaction with the nuclear S - shell protons at 1 GeV

The polarization of the secondary protons in the (p,2p) reaction with the S - shell protons of nuclei 4He, 6Li, 12C, 28Si, 40Ca was measured at 1 GeV unpolarized proton beam. The spin correlation parameters Cij for the 4He and 12C targets also were for the first time obtained as well. The polarization measurements were performed by means of a two - arm magnetic spectrometer, each arm of which was equipped with the multiwire proportional chamber polarimeter. This experiment was aimed to study a modification of the proton - proton scattering matrix in the nuclear medium.

The polarization of the secondary protons (P1,2) in the (p,2p) reaction with the S - shell protons of nuclei 4He, 6Li, 12C, 28Si, 40Ca was measured at 1 GeV unpolarized proton beam. The spin correlation parameters Cij for the 4He and 12C targets also were for the first time obtained.

Investigation of inelastic 40Ca(p,p')X reaction at 1 GeV

The polarization of the secondary protons in the inelastic (p,p') reaction on the 40Ca nucleus and the relative cross sections of this reaction at 1 GeV of the initial proton energy were measured in a wide range of the scattered proton momenta (K) at lab angles θ=13.5 and θ=21.0 degrees. The final protons from the reaction were detected by means of a magnetic spectrometer equipped with multiwire proportional chamber polarimeter.

Search for Two-Particle Muon Decay to Positron and Goldstone Massless Boson (FAMILON)

The experimental test of possible expansion for the Higgs sector is proposed. The lepton family violation will be studied. To reach this goal we are going to carry out the search for the scalar Goldstone boson in the neutrinoless muon decay mu+ to e+ and alpha. The asymmetry of the muon decay near the high energy edge of Michel spectrum is to be measured. To examine previous TRIUMF data the experiment FAMILON is prepared at the surface muon beam of JINR (Dubna) accelerator. The setup consist of the precision magnetic spectrometer and the device for muSR - analysis.
