I am doing my PhD thesis in the D0 Experiment, one of the two experiments which take place at the TeVatron, the proton-antiproton collider at Fermilab, USA.
First, I am working on the electromagnetic Calorimeter resolution;I correct the energy of electrons from geometrical effects. I will then developp a neural net in order to best mesure the energy of electrons, using trackers and calorimeter informations.
Secondly, my analysis work concerns the search of a supersymmetric signal in the data taken since end of 2001, in a R-parity violation context. I am studying two channels: lambda' couplings with double production of LSP decaying into leptons and jets, and lambda couplings leading to a final state with at least three leptons.

For my Ph.D. thesis I am working on the Muon Spectrometer of ATLAS, one of the LHC - detectors at CERN. I participated in the final commissioning of the alignment test system, which is needed for precise muon tracking, and prepared a C++ converter for test beam data of Trigger and Precision Chambers. During the this yearís test beam a first test of the Muon Track Reconstruction software package MOORE on real data will be possible. From the hardware side I am engaged with the set up of a cosmic ray stand, on which the functionality of packages of Monitored Drift Chambers and Resistive Plate Chambers will be checked, before they will be finally installed in ATLAS.

I am currently working in the field of Elementary Particle Physics at the Institute of Nuclear Physics in Krakow, within the ATLAS experiment at CERN.
The experimental part of my work consists of development and tests of the controls software for the multichannel power supply system of the Silicon Central Tracker of the ATLAS Inner Detector.
The theoretical part constists of Monte Carlo simulation of the minimum bias type events as well as on simulations of selected physics processes , preparing a massive production of MC events for the ATLAS experiment.
I am also involved in comparison between the fast simulation/reconstruction packages: fortran version of ATLFAST, used for several simulation studies presented in ATLAS Physics TDR, And Athena-Atlfast package written in C++/OO, which is based on the same algorithms implemented into new Athena framework.

For my PhD thesis I am working on BELLE.
This is the detector operating at KEKB e+e- asymetric collider at KEK. I am doing analysis of the data collected by BELLE. In this analisys I am looking for the decay B->D tau nu. It is importaint to measure branching fraction of the decay. This is not rare decay but it is hard to reconstruck. Although BELLE collected over 120 million pairs of BBbar it will be possible to see just several events.

The breaking of electroweak symmetry is still not understood. Many theories have been developed to explain the underlying mechanism. All of them introduce at least one new particle. In the Standard Model this is the Higgs Boson, while in other models --such as Technicolor-- a rich spectrum of new particles is expected. Experimentalists search for these new particles and precisely determine their properties to test the various predictions.I am searching for particles from technicolor theories in data recorded by the OPAL experiment at LEP and study precision measurements on Higgs Boson properties at a future electron positron collider such as TESLA.

I'm doing my PhD research on the ZEUS experiment, at the HERA collider at DESY. At HERA positrons (or electrons) of 27.5 GeV collide with protons of 820 GeV, with a center of mass energy of about 320 GeV. This allows to investigate the structure of the proton up to the linear scale of 10^{-16}
m, and allows tests for a wide spectrum of QCD phenomena, both in the deep inelastic scattering (DIS) and photoproduction regimes.
My current analysis is centred on the search of SUSY particles, produced through R-parity violation couplings, a possible candidate of new physics beyond the Standard Model.
I'm also engaged with the work of monitoring of the FMUON detector, a muon detector for the forward region with respect to the incoming proton direction.
In order to strenghten and improve the muon detection, I have developed a new software for matching the informations coming from the FMUON detector and the central tracking detector of ZEUS.
