I have started my Ph.D work in the year 2000. For my thesis I am working on ZEUS, one of the two colliding beams (e-/e+ p) experiments at the HERA- accelerator at DESY, Hamburg. In the year 2001 the HERA ring has been upgraded. Also the ZEUS detector is upgraded, in particular with a silicon micro-vertex detector. I have participated in the (cosmic) tests of this new detector. For the cosmic rays I have written a Kalman filter track fit program, which is also foreseen to be used for the after upgrade HERA data analysis. With the data we expect in the year 2002 I want to do a measurement on the charm (beauty) production cross section in deep inelastic scattering.

I am working on NA49 - The large acceptance hadron detector for an Investigation of Pb-induced Reactions at the CERN SPS. In 2000 I visited CERN for three months. I took part in NA49 data taking and analysis of the proton-proton and pion-proton data collected by NA49 at beam energy of 158 GeV. In this analysis measurement of the particle ratios has been performed. Last year I worked on my diploma thesis - measurement of the baryon number transfer from the projectile to the final state in proton-proton reaction. My current activities are concentrated on dE/dx calibration of the NA49TPCs.

For my PHD thesis I am working on PAMELA, a magnetic spectrometer to be installed on board of Resurs-DK1 spacecraft on 2003. PAMELA is mainly devoted to study the origin and evolution of matter in the galaxy and search for antimatter and dark matter of cosmological significance. I am engaged with the development of on-board software that provides for the whole control of Pamela subdetectors (DAQ, calibration, slow control) and the communication with the spacecraft and the Earth. During the data taking, I will work on data analysis, studing the antiproton and positron fluxes in Cosmic Rays up to high energy ( 190 GeV for positron and 270 GeV for antiproton).

For my Ph.D. thesis I am working at CDF II at Tevatron /Fermilab. One of my collegues and I implemented the pattern recognition strategies for the silicon. In these strategies a KalmanFitter is used, which we include from the DELPHI code. We are responsible for the silicon tracking system on trigger level and on production. I am not yet working on an analysis but I am interested in b-physics.

Since 2000, I am working in the Joint Institute for Nuclear Research in Laboratory of Particle Physics in the Dubna Compact Muon Solenoid (CMS) group for my Phd thesis. There are two fields of my current work. The first one is the development of the common software for CMS physics simulation and reconstruction. Now I have good enough experience to work with simulation program package CMSIM as well as in muon reconstruction and data analysis using ORCA package. Therefore, I was recently involved in the Monte Carlo studies of the exclusive B-trigger. In the CMS collaboration, Dubna has a full responsibility for production of cathode strip chambers for the First Muon Station (ME1/1). So, the second field of my work is preparing and development of software for testing ME1/1 layer production and final detector quality control to provide a high spatial resolution of strip chambers and timing resolution of trigger under real conditions (strong magnetic field and high background rate) of ME1/1 operation.

The measurement of the W mass is performed by all four LEP collaborations in the energy range from 161GeV to 207GeV using W pair events. A precise measurement of the W mass is an important test of the Standard Model and provides a constraint on the mass of the Higgs boson. Inside DELPHI the so-called ideogram method was developed to take into account many ambiguities that arise in the reconstruction of an event. I am working for DELPHI on the measurement of the W mass in the semileptonic channel. In this channel one W decays in a lepton and its neutrino and the other in a quark anti-quark pair. The most important ambiguity arises from the fact that when an electron or a muon is detected it could either be produced from the W directly or via an intermediate tau.
