High Energy Physics Department
The head of the
department is the Corresponding Member of the National Academy of Sciences of
Ukraine,
Doctor of Physics and
Mathematics, Professor V.M. Pugatch
The High Energy Physics department was
established in 2005 and now consists of more
than dozen of members,
including 1 professor, 6 doctors and also 10 engineers, one junior researcher,
3 post- and 2 under- graduate students.
The main areas of research:
·
Properties of interactions in
nuclear matter at high temperatures and densities
·
The excitation and decay of heavy
hadrons at relativistic energies
Within these topics:
Ø Study of the CP violation in B
mesons decays produced in proton-proton collisions with up to 13 TeV energies (experiment LHCb (CERN)).
This phenomenon is considered as one of the possible causes of the Matter-Antimatter
asymmetry of the Universe.
Ø Running and working on upgrade of
the LHCb experiment, including the support for the functioning
of the radiation monitoring system (RMS) developed in KINR of NASU.
Ø Data analysis of D0 (FNAL, USA), LHCb (CERN) and HERA-B (DESY, Hamburg) experiments.
Ø Theoretical modeling and event
reconstruction in the LHCb, CMS (CERN), PANDA (GSI /
FAIR, Darmstadt) experiments.
Ø Development and testing of detector
systems for the future experiments:
-
CMS
(GSI / FAIR, development of detector modules of the Silicon Tracking System)
-
ILC
(Japan, forward calorimeters R&D)
-
PHIL
(LAL, Orsay)
·
Development of new methods and
equipment for high-energy physics experiments and other branches of science and
technology
Ø The physics and technical basis of
spatially fractionated radiation therapy is being developed.
The most significant scientific results:
✦ HERA-B experiment: the
cross-sections of the strange hadrons production in proton-nucleus collisions
at an energy of 920 GeV were measured with the world's highest accuracy.
✦ LHCb
experiment: the characteristics of the combined parity violation have been
studied using measurements of time evolution of neutral B mesons and their
anti-partners decays. As the results agree with the
predictions of the Standard Model (SM), the question of the asymmetric
development of the universe remains open - the unique phenomenon presumably
caused by physical processes beyond SM.
✦ D0 experiment (Tevatron,
FNAL): the mass of the top quark was measured with an accuracy of 1% using 9.7
fb -1 of integrated luminosity data collected in proton-antiproton collisions
with energy of 1.96 TeV.
✦ Searching for the quark-gluon
plasma signals in nuclear-nuclear collisions, the differential cross-sections
of different hadrons production in the LHCb experiment
were measured. The nuclear modification factor of primary and secondary J / ψ mesons production is measured using
data of p-Pb collisions at an energy of 8 TeV.
✦ For many years, the Radiation
Monitoring System has been successfully operating in the LHCb
experiment (development of KINR), providing independent luminosity measurements
for the experiment.
✦ Physics and technical fundamentals
have been developed for new target systems and detectors for high-energy
physics and other interdisciplinary fields of science. It was applied to
produce microporous jet target, metal-foil detectors, metal microstrip
and micropixel detectors, metallic microstrip target detector, etc.
