Research Experience
From March 1993   Institute for Nuclear Physics, Moscow State University ,
  Department of Experimental High Energies Physics

From the beginning of my scientific research activity (1993, Moscow State University, Department of Nuclear Physics, Faculty of Nuclear Physics) I have been dealing with various phenomenological aspects of high energy physics related to present and future colliders in the TeV energy region.

My first publications as well as diploma work (which was done under the supervision of professor E.E. Boos) were devoted to phenomenological study of Higgs boson production processes at the TEVATRON collider. In the framework of these studies exact calculations of signal and background processes as well as event simulation at the parton level have been done.

The next work was related to study of Higgs boson production under the resonance threshold at LEP II. It was shown that the Higgs signal is not negligible under the mass threshold and it is practicaly free from the background for the special values of $\sqrt{s}$ and $M_H$.

In 1995, after graduating from MSU I continued my studies as a Ph.D. student at Experimental High Energy Physics Lab. in the Institute of Nuclear Physics of MSU. I have been directly involved in theoretical and phenomenological analysis -- within the DØ collaboration -- devoted to a search for single top quark production in the electroweak processes. Early 1996 I joined the ``Single Top'' subgroup (within the ``Top'' group of the DØ collaboration) headed by Prof. Ann Heinson. All the signal processes were analyzed theoretically, MC generators were created for simulation of single top production at DØ and analysis of all the main kinematic variable distributions for the signal and background was made. At the research position at the Institute of Nuclear Physics of Moscow State University I was working on MC simulation of single top signal[14-17], studied background for this processes, and performed data analysis at DØ. I have applied the neural network technique for this search and it is significantly improved the result.

My further activity was related to study of anomalous $Wtb$ couplings and phenomenological analysis of such deviations from the Standard Model use the single top quark production at the TEVATRON and LHC.
