Dr.Sci. Filin VM) within the research on "Patterns of excitation and decay of heavy hadrons at relativistic energies." In 2012 he received the following key results: In the Large Hadron Collider (CERN, Geneva) made physical investigations of collisions of protons with protons at enerhiyeyi 7 and 8 TeV (s.ts.m) experiment LHCb. For the first time observed the decay of B-mesons composed of charm- and beauty-quarks in chotyrohchastynkovomu channel (Bs > J / ? + 3?) to form a charm-mesons and three ?-mesons. The results of measurements made it possible selection among the many theoretical models, such as the closest reproducing experiment. (LHCb Collaboration. First observation of the decay Bs > J / ? + 3?. Phys.Rev.Lett. 108 (2012) 251802). According to the results of other studies involving employees INR NAS of Ukraine in 2012 published 52 scientific articles. With Radiation Monitoring Systems (CPM) established staff NASU INR to eliminate unintended radiation damage silicon sensors and microelectronics internal tracker and monitoring luminosity LHCb experiment, was measured dose absorbed by silicon sensors internal tracker LHCb experiment in 2012. The integrated luminosity of 2.0 inverse femto-Bar, the dose of 470 Gray and consistent with the expected radiation exposure, estimated by Monte Carlo calculations. Reviewed luminosity LHCb experiment in 2012. (VM Filin, Ohrimenko O., Yakovenko VM, etc.) From the data obtained at HERA Collider (ZEUS experiment) calculated differential cross sections as functions of the parameters of the photon and hadron jet (transverse energy and psevdoshvydkisnist) and variables describing the event (virtual photon and variable Byorkena). Theoretical calculations using theoretical predictions of order basically describe experimental data. (Measurement of isolated photons accompanied by jets in deep inelastic ep scattering, Phys Lett B 715 (2012) 88-97). (VE Aushev, Zhmak NV) By applying the hydro-kinetic approach was the influence of fluctuating sawtooth structure in initial conditions on spectrum and collective evolution of matter formed in heavy ion collisions. It was found that the presence of transversal trubkopodibnyh fluctuations in initial conditions greatly affect the hydrodynamic evolution and leads to significant structures in the calculated spectra of pions. (Borisov MS) As part of the design elements of the detector system experiment SVM (FAIR, Darmstadt) in experiments on test beams and laboratory studies have found that bilateral Silicon mikrostripovi detectors type CBM04 on their characteristics (eg, radiation resistance) meet the requirements for building on the basis of Silicon track System. (Lymanets AJ, Malygina GM, YV Panasenko, MV Pugach, VA nod, owl VM) In collaboration with the laboratory of plasma technology developed and manufactured the first micro-modules stripovyh metal detectors with variable increments (up to 2 microns) Strip and executed supply the first batch of detectors (5 pcs.) On the order of DLS (DIAMOND LIGHT sourc, UK). (Kovalchuk OS, VM Police, VA nod, VM Filin, DI Storozhik, O. F., etc.). Product Description popup.authors Аушев В.Є. Борисова М.С. Жмак Н.А. Ківа В.О.
