Biographical SketchMarek Zielinski obtained his education in Poland receiving MS in Physics in 1974 and PhD in 1978 from the Jagellonian University. He first joined the Rochester group in 1981 to participate in the research program at Fermilab. During the following years, he worked, alternatively, at Fermilab with the Rochester group and at the Jagellonian University. His research related to results from Fermilab experiment E272 on Primakoff and diffractive production of mesons constituted the foundation for his Habilitation Degree, received from the Institute for Nuclear Research in Cracow in 1987. Shortly afterwards he moved to the United States. At the Jagellonian University, he held teaching positions and did research in theory and phenomenology of particle physics. He was also an editor for Acta Physica Polonica from 1978 to 1990.
While at Fermilab, Dr. Zielinski has worked on various aspects of experiments E272, E706, E672, E781, and, currently, DZero. Dr. Zielinski has made presentations at numerous conferences and has published more than 100 articles in refereed journals. He also has been active in organizing workshops and conference sessions related to his research interests. In recent years he has has served as head of the Calorimeter Simulation and Calorimeter Software Algorithms Groups at DZero (1997-2000), as co-organizer of "Multi-Hadron Final States" session at International Conference on Deep Inelastic Scattering, DIS 2002, as co-convener of the Run II QCD Physics Group at DZero (2000-2002), as co-Chair of the Calorimeter Task Force at DZero (2002-2003) and as Co-Leader of the Run II Top Physics Monte Carlo Subgroup at DZero (2002-present).
ResearchDr. Zielinski's research interests are in High Energy Physics. He started his activities in the field as a theorist. His Master's and PhD theses were concerned with theory and phenomenology of particle production in high energy interactions, particularly within the frameworks of the quark model and perturbative QCD. His participation in the experimental program began at Fermilab experiment E272 with work on meson excitation in the nuclear Coulomb field and diffractive interactions of pions with nuclei which led to the first determination of the radiative width of the a1 meson. Later, as a member of Fermilab experiment E781, he was involved with the new determination of the radiative width of the a2 meson.
Next, Dr. Zielinski participated in experiment E706, aimed at testing QCD predictions for large momentum-transfer production of direct photons and mesons. He was in charge of various aspects of the reconstruction software, Monte Carlo simulations and data analysis. Results from E706 indicated the need for improvements in the theoretical calculations and received significant attention from theorists and phenomenologists, as well as from the heavy-ion community at RHIC. In addition, Dr. Zielinski took part in the research program of experiment E672 on hadronic production of states containing charm and bottom quarks.
Subsequently, Dr. Zielinski focused on the Fermilab collider experiment DZero. In the period leading to the start-up of Run II, he was responsible for the simulation of the calorimeter detectors and headed the calorimeter-software group. Later, he was appointed a co-chair of Calorimeter Task Force charged with investigation of a wide range of issues in the performance of calorimeter hardware and software. This effort provided an improved understanding of calorimeter signals. Within QCD Group, he also guided detailed studies of jet properties, essential not only for physics analyses but also for commissioning of the calorimeters.
As a co-convener of QCD Physics Group, Dr. Zielinski was directly involved in the analyses of inclusive jet and di-jet cross sections - the flagship measurements of QCD Group. The results on the inclusive jet cross section provide powerful constraints on global fits to parton distributions within the nucleon, while distributions in di-jet mass are of particular interest in searching for quark substructure or any hypothetical heavy resonances, a long-sought possibility for physics beyond the standard model. The investigation of angular correlations between jets has already provided a sensitive probe of perturbative QCD and event generators, and was highlighted as a "Fermilab Result of the Week" in Fermilab Today.
Since 2002, Dr. Zielinski has been a co-leader of the Monte-Carlo subgroup of Top Physics Group, in charge of providing signal and background Monte-Carlo samples for the measurements of the top-quark properties and production cross-sections. His participation in Fermilab Workshops on Matrix Element Techniques and Monte Carlo Tuning, and experience with QCD and calorimeter issues, serve well to complement this work.
Dr. Zielinski's future research interests are in the top-quark physics and searching for novel physics aspects related to electroweak symmetry breaking, at DZero and at the LHC collider.
