Spin physics in few body systems at Nuclotron

The review of the recent results on spin effects in few nucleon systems obtained at LHEP-JINR are presented. The data on the deuteron analyzing powers in different reactions in the wide energy range demonstrate the sensitivity to the spin structure of the light nuclei. The future plans on the studies with polarized deuterons from new polarized ion source at Nuclotron will be reported.

Recent results with polarized deuterons and polarimetry at Nuclotron-NICA

Recent results on the deuteron analyzing powers obtained in collisions of polarized deuterons with protons and light nuclei at intermediate and high energies are reported. The obtained results are sensitive to the spin structure of the short range correlations. The prospects of the spin program for hadronic reactions at Nuclotron-NICA facility is discussed. The polarimetry developments are also presented.

Possible dibaryon states produced in4He-proton interactions

In the hydrogen bubble chamber study of the4Hep→dppn reaction at incident alpha 8.6 GeV/c momentum the structures in the two-proton effective mass distribution are observed at 2,035±15 MeV and 2,137±15 MeV. Possible nature of the effect is discussed.

Review of the top quark mass measurement at the CDF in p\(\bar p\) collisions at \(\sqrt s \) = 1.96 TeV

Upgraded Tevatron RUN-II luminosity has opened a new chapter in a modern heavy quark studies—a top physics: a dozen level of a Tevatron Run-I top events statistic now is being replaced by hundreds events. This work reviews a mass measurement of the top quark produced at (sqrt s ) = 1.96 TeV in p (bar p) collisions at the Collider Detector at Fermilab (CDF) with the integrated luminosity samples up to 359 pb−1. The review covers the M(top) measurement using mainly the so-called template methods both in the “lepton + jets” and “dilepton” channels of top quark decay. The CDF top quark mass obtained in the lepton + jets mode is currently the world’s most precise single measurement of this important physical parameter. This work summarizes the essential results of the CDF top quark mass measurement achieved and published for the recent 2003–2005 period.

Experiments on the study of deuteron-proton interaction at internal target at nuclotron

The experimental program on the study of deuteron-proton interaction at Internal Target at Nuclotron is discussed. Recent results on the deuteron vector and tensor analyzing powers in dp-elastic scattering obtained at intermediate energies are presented. The status of the DSS setup upgrade is reported.
