3 Computer Skills Programming Languages: C++, FORTRAN, Shell script, HTML, Latex. Analysis Tools: Toolkit) ROOT, ORANGE (ZEUS analysis software), BAT (Bayesian Analysis Research Experience During my Ph.D., I had a chance to have a nice experience of working in the ZEUS collaboration. I have worked on the measurement of the cross section of e p scattering at high Bjorken-x. The data sample used for the final results consisted of the whole e p data collected by ZEUS during HERA-II operation, which corresponds to an integrated luminosity of 187 pb 1. During my Ph.D. I occasionally visited to the Max Planck Institute for Physics, Munich, Germany and Deutsches Electron Synchrotron (DESY), Hamburg, Germany. Deep inelastic scattering (DIS), is by far the most accurate process for extracting the parton distribution functions (PDFs) and hence enhancing the knowledge about proton structure. These PDFs cannot be calculated from the first principles and need to be extracted from the experimental measurements. A precise knowledge of the PDFs is particularly important when the LHC has started to deliver proton-proton collisions. Since the protons are composite particles, consisting of gluons and quarks, the p p cross sections of hard scattering processes depend on the parton distributions in the proton. The LHC can make some measurements of these quantities, but will rely to a large extent on the precision data collected at other colliders, in particular data from HERA. The PDFs are found to decrease very quickly for x > 0.3. The high-x region covered by fixed target experiments correspond to low Q 2. The highest measured points in the DIS regime are for x = 0.75 by BCDMS, one of the fixed target experiments. The data collected at HERA cover much large phase space than the previous fixed target experiments. The Q 2 region covered increases substantially to 30,000 GeV 2 and x reaches to lowest point x = A first attempt to explore the region of x 1 was performed by the ZEUS collaboration on the data, collected with the ZEUS detector before the luminosity upgrade of the HERA accelerator. During my Ph.D. I measured the e p cross sections up to x = 1 with ZEUS e p data collected during , which is more than ten times in luminosity than the ZEUS published high-x e p data. Also the reconstruction method is improved compared to the published results. Thus it is expected that the results from this study will put more constraints on the existing PDFs in the high-x region. The events having the jet very close to the beam pipe in the direction of proton, actually correspond to very high Bjorken-x values and for such events Bjorken-x cannot be reconstructed using the information from the detector. Such events were put in one bin, x edge < x < 1, where x edge is the maximum value of Bjorken-x that can be reconstructed in the detector. Since the form of PDF is not well known in this region, a cross section integrated over the bin is calculated. For the events in which the jets were well within the detector the Bjorken-x was reconstructed using information from the scattered electron and the jet and double differential cross sections were evaluated for such events. In DIS at HERA, scattered electron plays an important role in the event reconstruction, so the calibration of the energy of the scattered electron was done to have precise measurements of the cross sections. The energy of the electron was corrected for different detector effects like non-uniformities in the calorimeter, dead material traversed by the electron from interaction point to the calorimeter, shower sampling in the calorimeter and leakage at the ends of the calorimeter. Jets were calibrated using one jet events based upon p T -balance between scattered electron and the jet. The interaction vertex position is used to reconstruct the position and angles of the final state particles originating from the primary interaction. In ZEUS X and Y vertex spreads were very small, however the longitudinal vertex distribution (Zvtx) had non negligible width. The shape of the Zvtx depends upon the time period during which the data had been collected, as beam conditions may change with time. For better description of the data Zvtx, MC Zvtx distribution must be derived from the
4 used data sample. This method was opted and the efficiency corrected data Zvtx was fitted using a sum of 9 Gaussian functions. The resulting fit function was used to re-weight MC Zvtx. The systematic uncertainties from different sources were estimated and included in the cross section measurement. This measurement is expected to constitute an important constraint not only on PDFs at large-x but in the whole phase space, because of the inherent couplings between the small and the large-x PDFs.
