Participants of the 23rd International Baldin Seminar, 2016
The XXIII International Baldin Seminar on High Energy Physics Problems “Relativistic Nuclear Physics and Quantum Chromodynamics”, named “Baldin autumn”, was held on 19-24 September 2016 in the Big Conference Hall of the Laboratory of High Energy Physics JINR. Since this year is the 90th anniversary of Alexander Mikhailovich Baldin, the Seminar was dedicated to his memory.
The opening of the Seminar was attended by JINR Director Academician V.A. Matveev, VBLHEP Director Professor V.D. Kekelidze, Deputy head of the City Administration N.A. Smirnov.
Greeting the participants of the Seminar, V.A. Matveev emphasized the scientific and organizational contribution of A.M. Baldin and wished successful holding of the Seminar.

V.D. Kekelidze spoke about the importance of the Seminar and the support of the International Union of Pure and Applied Physics (IUPAP). N.A. Smirnov addressed the participants on behalf of The City Administration.
The Seminar continued the series of traditional meetings that was established by Academician A.M. Baldin jointly with Academician M.A. Markov in 1969.
On the first day of the seminar, before lunch, the reports were devoted to activities of A.M. Baldin. Professor A.I. Malakhov, who had headed the Laboratory of High Energy Physics for 10 years after Baldin, made a report “A.M. Baldin: from photoproduction to relativistic nuclear physics”.
Chairman of the section, Professor E. Tomasi-Gustafsson (France) gives the floor to Professor V. Burov (JINR)
Professor V.V. Burov from the Bogoliubov Laboratory of Theoretical Physics JINR made a report “Baldin autumn “, in which he spoke about the discovery of the cumulative effect and history of the Seminar, as well as about a number of meetings with A.M. Baldin. VBLHEP Deputy Director A.D. Kovalenko presented a proposal made jointly with A.M. by Baldin called “100 TeV Nuclotron”. BLTP Chief Scientific Researcher S.B. Gerasimov spoke about the work conducted together with A.M. Baldin on electro-magnetism of hadrons. The son of A.M. Baldin, VBLHEP Head of Sector A.A. Baldin described some methodological and philosophical ideas of Academician A.M. Baldin.
VBLHEP Head of Sector P.I. Zarubin, in his report “A.M. Baldin and relativistic nuclear physics with nuclear track emulsion “ reported on a number of interesting results obtained on nuclear beams of the Synchrophasotron and the Nuclotron. Professor from the USA L. Pondrom made an interesting report about the Soviet atomic project. Professor N.P. Konopleva from Moscow shared her memories of collaboration with A.M. Baldin..
At the plenary session of the first day of the Seminar which was held after lunch, reports of the major collaborations of the Large Hadron Collider were heard, in particular, the CMS collaboration (I. Gorbunov, JINR) and the ATLAS collaboration (M. Przybycień , Poland). A. D. Kovalenko (JINR) gave a presentation on the preparation of the NICA complex with polarized protons and deuterons. E. Tomasi-Gustafsson (France) reported on the advances in the study of the hadron electromagnetic structure. V. Kuvshinov (Minsk, Belarus) made a theoretical report about the color states evolution in vacuum at large distances.

On the remaining days of the Seminar, except the last one, plenary sessions were held before lunch and three parallel sessions were held after lunch. On the last day, 24 September, only one plenary session was held.
The most significant, both theoretical and experimental results were heard at plenary sessions. Presentations were made by participants from JINR, Russian cities: St. Petersburg, Moscow, Gatchina, as well as from Kazakhstan, Sweden, Germany, France, the USA, Brazil, South Africa, the Czech Republic, South Korea, Poland, Slovakia, Belarus.
On the second day of the Seminar, theoretical reviews were presented: D. Blaschke (Recent Theory Developments for NICA), S. Kulagin (Nuclear parton distributions, A. Andrianov (Chiral imbalance in QCD), O. Teryaev (Hyperons polarization in heavy-ion collisions), A. Zakharov (Graviton mass bounds from an analysis of bright star trajectories at the Galactic Center), as well as new experimental data V. G. Nedorezov (GRAAL), J. Ritman (FAIR/PANDA).
On the third day, the following interesting reports devoted to experiments should be noted: A. Kupsc and A. Dbeyssi (BESIII), D. Marchand (PRAE) and C. Baessler (Nab). The Bethe-Salpeter approach was discussed in theoretical reviews of V. Burov and L. Tomio, J. Cleymans presented the thermal model for small systems and A. Kataev discussed the new renormalization-group representation. .

On the fourth day, P. Frederic, M. Tokarev, A. Taranenko, P. Federicova discussed the latest data from experiments at RHIC/STAR and LHC. S. Olsen made an interesting report on the probing of the X(3872) meson structure with near-threshold pp and pA collisions. E. Golovach introduced the report on behalf of the CLAS/CLAS12 collaboration about new states of hadronic matter. Theoretical reports of S. Gerasimov, V. Lukyanov and B. Slowinski were devoted to various aspects of photon – and pion – nucleus scattering.
On the fifth day, V. Ladygin presented a review on investigations of compressed baryonic matter at GSI, R. Schicker and S. Kiselev presented the latest results of the ALICE/LHC collaboration. Yi. Wang spoke about polarization measurements for np scattering. I. Savin discussed the azimuthal asymmetries in the COMPASS experiment. H. Machner devoted his report to η mesons bound states, and Yu.

On the final day of the Seminar, the status and prospects of experimental studies were discussed. So, W. Barth in his report presented a superconducting CW-LINAC for heavy ion acceleration at GSI. V. Kekelidze devoted his detailed report to the NICA project which virtually is the future of VBLHEP. M. Janek spoke about research at the Nuclotron using polarized and unpolarized deuteron beams. M. Pasyuk made an overview of the GlueX experiment at JLAB. An overview report of S. Shimanskiy was dedicated to the 45th anniversary of the research of the cumulative effect.
P. Zarubin presented the results of the BECQUEREL experiment for studying nuclear clustering in light nucleus. A. Malakhov in a report on development of the the Baldin approach for the relativistic nuclear interactions demonstrated a good coherence of predictions with the LHC experimental data.
The parallel sessions were grouped under the following topics: relativistic heavy ion collisions, dynamics of multiparticle production, applied use of relativistic beams, quantum chromodynamics at large distances, hadron spectroscopy and multiquarks, cumulative and subthreshold processes, polarization phenomena and spin physics, studies of exotic nuclei in relativistic beams, accelerator facilities (status and perspectives), structure functions of hadrons and nuclei, the NICA/MPD project at JINR. The parallel sessions were attended by scientists from JINR, Russian cities: Moscow, St. Petersburg, Gatchina, Saratov, Nizhniy Novgorod, Samara, Yoshkar-Ola, a number of countries such as Serbia, Kazakhstan, the Czech Republic, Poland, Ukraine, Iran, China, Belarus, Mongolia, and Romania.
Almost all reports raised great interest and useful scientific discussions.
