1. Single-Photon Events in the DELPHI Experiment
Abstract : A series of studies pertaining to the STIC calorimeter at the DELPHI experiment at LEP is presented, and a new generation of fast wire scanners for emittance measurements at PS is described. The STIC studies are centered around a single-photon analysis, in which the reaction e+ e- -> gamma + invisible particles was studied at center-of-mass energies of 161, 172 and 183 GeV. READ MORE

2. Luminosity evaluation and fragmentation studies for the DELPHI experiment at LEP
Abstract : The first subject addressed in this thesis is the contribution of the VSAT luminosity to the lineshape analysis, i.e. to the extraction of the mass and width of the Z0 boson from LEP1 DELPHI data. The VSAT detector has contributed to the lineshape parameter determination by providing a relative luminosity measurement of high accuracy. READ MORE

3. Hadronic Structure Measurements of the Photon by DELPHI at LEP II
Abstract : This thesis is mainly an analysis of data taken by the VSAT detector in the DELPHI experiment at the LEP II collider at CERN. The analysis spans from 1998 to 2000, with a center of mass energy ranging from 189 to 206 GeV. READ MORE

4. Study of Two-Photon processes at low Q2 using the VSAT calorimeter in the DELPHI experiment
Abstract : The study is based on data collected at the LEP II accelerator during the second period of the Large Electron-Positron collider operations (1996-2000). During that time the DELPHI (DEtector with Lepton, Photon and Hadron Identification) experiment collected about 90 Gb of data on tape corresponding to 687-691 pb-1 of luminosity. READ MORE

5. Searches for New Physics in Single Photon Events and a Search for Charginos at the DELPHI Experiment
Abstract : A search for new physics using events with a single photon and missing energy has been made at the DELPHI experiment together with a search for charginos. The results were based on data collected up to and including the final year of 2000. READ MORE
