HEP Group Vinca is a part of the Laboratory of Physics of the Vinca Institute of Nuclear Sciences. The institute is situated in Vinca, in vicinity of Belgrade, capital city of Serbia.
Carrying the experience from the DELPHI experiment at LEP, our group is involved both in physics and detector R&D for the future linear colliders ILC and CLIC as well as in the heavy-flavour studies at H1 and ATLAS experiments. Through the activities of our Group, Vinca Institute of Nuclear Sciences is participating in the FCAL Collaboration at ILC, ATLAS Collaboration at LHC and the H1 Collaboration at HERA. In 2006 HEP Group was granted an international project by the German Research Foundation for research on proton structure carried-out at the H1 experiment in close collaboration with DESY Hamburg and Zeuthen, Germany.
Our research is also a subject of a national co-operation - Vinca Institute of Nuclear Sciences is forming an extended institution at ATLAS, together with the Institute of Physics, Belgrade, Serbia.
Most of our studies are not confined to a single topic but rather have impact to various measurements and analysis.

LUMINOSITY MEASUREMENT AT FUTURE LINEAR COLLIDER
In order to perform rich physics program of physics beyond the Standard Model, the ILC detector is faced with unprecedented challenge for the most of the subsystems. One of the most important aspects that should be considered is measurement of the integral luminosity because its uncertainty affects many precision measurements, and limits some of them as the additional component of a systematic error. We are involved in the issues of the simulation and experimental control of the leading systematic effect in luminosity measurement at future linear colliders (ILC and CLIC) originating from SM four-fermion production as physics background as well as from the beam-induced effects.
There is one ongoing PhD thesis and one recent PhD promotion related to this field.

HEAVY FLAVOUR IDENTIFICATION AND PHYSICS AT ATLAS
Vinca Institute's team at ATLAS is involved in b-quark identification in terms of its flavour and charge through the Flavour Tagging and B Physics WGs. In addition we are involved in the study of Bs->J/Psi Phi processes for the purpose of measurement of the CP violation phase in these decays originating from the direct b-bbar oscillations.
There are two PhD theses ongoing in this framework.
It is worth to mention that multivariate approach to identify b-flavour was employed in the measurement of the proton b-content presented in a PhD work (DESY-THESIS-2011-045) that summarizes several years of our activity at the H1 experiment. This work was supported through the project of the German Research Foundation (DFG) No. 436SER113/1/0-1, carried out at DESY and at the Vinca Institute of Nuclear Sciences, Belgrade, Serbia.
