High Energy Physics

• the Department of Experimental High Energy Physics (headed by DSc professor P.F. Ermolov)
• the Department of Theoretical High Energy Physics (headed by DSc V.I. Savrin)
• the Laboratory of Nuclear Research at the SINP branch in Dubna (headed by PhD A.V. Kulikov).

Investigations in high energy physics are one of the leading studies at the Institute. They were started in late 1960s on the initiative and with support of academicians S.N. Vernov and A.A. Logunov.

Experiments in high energy physics are being run on accelerators at the largest scientific centers of Russia:

• the Institute of High Energy Physics (IHEP, Protvino)
• the Joint Institute for Nuclear Research (JINR, Dubna)
• the Institute of Theoretical and Experimental Physics (ITEP, Moscow)
• the scientific centers abroad in the USA, Germany and Switzerland.

The scientists of the SINP take part in investigations of proton antiproton interaction with use of bubble chambers "Lyudmila" and "Mirabelle" at the IHEP accelerator. A measuring-computational complex which is the largest in the system of Academy of Science and High School was created in the SINP for the analysis of experimental data from bubble chamders. A large programme of the investigations of multipartial processes in hadron dynamics was carried out with use of this complex on the basis of processing and analysis of the data from European Hybrid Spectrometer.

For a number of years the properties of leading particles in hadron-nuclei interactions were studied using the Stintillation Magnetic Spectrometer constructed at the JINR synchrofasotron.

The scientists of the SINP perform measurements of the cross sections of near-threshold production of charmed particles at the IHEP array. A spectrometer with a vertex detector, was created with a decisive contribution by the SINP.

The research in high energy physics carried out at the SINP may be classified as a large scale international cooperation. The SINP within a broad international collaboration "ZEUS" at the HERA collider in DESY carried out precise measurements of the proton structure, searches for exotic states, study of hadron and lepton multiple births. One of the major events was the experimental discovery of the sixth heaviest quark, playing a key role in modern particle physics by the "Do" collaboration with participation of our physicists at FNAL collider.

The unique results were received at the BNL accelerator in the experiment on search for mesons with extraordinary quantum numbers, where a group of our scientists participate. The scientists of SINP also participate in elaboration and modernization of the detectors for a new generation of crossed beams accelerator in Cern. The theorists of the SINP have the well-known achivements in solving key problems of field gauge theories and elaboration of unperturbative methods in elementary particle physics.
