1. 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

2. Nonlinear Evolution in High Energy QCD
Abstract : QCD at very high energies is still not very well understood. Difficulties arise from a strong non-linear dynamics and also from nonperturbative physics. Detailed analytic calculations are often only possible either for simple toy models, or for asymptotically high energies. READ MORE

3. Isospin Breaking in Kaon Decays to Pions
Abstract : The five different K -> 3 Pi and the three K -> 2 Pi decays are calculated in Chiral Perturbation Theory. The calculation is done using different approximations, to study whether this changes the result significantly. First the isospin approximation is used. Discrepancies are then found between theory and experiment. READ MORE

5. Jet Production and Parton Dynamics in Deep Inelastic Scattering
Abstract : Hard QCD processes have been studied by measuring the di-jet event rate for deep inelastic scattering in the kinematic range 5 < Q2 < 100 GeV2 and 10-4 < x < 10-2. The jets we re reconstructed using the cone algorithm in the hadronic center-of-mass frame in which the transverse momentum of the jets were required to be greater than 5 GeV. READ MORE
