Towards light scalar meson structure in terms of quark and gluon degrees of freedom
S. V. Molodtsov, T. Siemiarczuk, A. N. Sissakian +2
The origin of the lightest scalar mesons is studied in the framework of instanton liquid model (ILM) of the QCD vacuum. The impact of vacuum excitations on the sigma-meson features…
QCD Matter: A Search for a Mixed Quark-Hadron Phase
A. N. Sissakian, A. S. Sorin, V. D. Toneev
Physics aspects of a JINR project to reach the planned 5A GeV energy for the Au and U beams and to increase the bombarding energy up to 10A GeV are discussed. The project aims to s…
Observation of New Resonance Structure in the Invariant Mass Spectrum of Two gamma-Quanta in dC-Interactions at Momentum 2.75 GeV/c per Nucleon
Kh. U. Abraamyan, A. N. Sissakian, A. S. Sorin
A new resonance structure at M = 355 \pm 6 \pm 9 MeV is observed in the invariant mass spectrum of two gamma-quanta produced in the reaction d + C => gamma + gamma + x at momentum…
NLO QCD method of the polarized SIDIS data analysis
A. N. Sissakian, O. Yu. Shevchenko, O. N. Ivanov
Method of polarized semi-inclusive deep inelastic scattering (SIDIS) data analysis in the next to leading order (NLO) QCD is developed. Within the method one first directly extract…
Towards Searching for a Mixed Phase of Strongly Interacting QCD Matter at the JINR Nuclotron
A. N. Sissakian, A. S. Sorin, M. K. Suleymanov +2
Available experimental data in respect to a possible formation of a strongly interacting mixed phase are outlined. A physical program is formulated for new facilities being opend i…
