1. Searches for exotic stable massive particles with the ATLAS experiment
Abstract : This thesis presents two signature-based searches for exotic long-lived particles using experimental data collected by the ATLAS experiment at the Large Hadron Collider (LHC) at CERN. At the LHC, proton-proton collisions take place at the world-record center-of-mass energy of 7 TeV and luminosities of up to 3×1033 cm-2s-1 . READ MORE

2. Studies of triggering and exotic particle searches at ATLAS, and a search for trapped monopoles
Abstract : The ATLAS detector at the LHC operated through 2011 and 2012 with 7 and 8 TeV centre-of-mass energy of its colliding proton bunches, respectively. One if its main objectives is to search for physics beyond the Standard Model. READ MORE

3. QCD Phenomenology of Heavy Particle Dynamics
Abstract : In this thesis the phenomenology of Quantum Chromo Dynamics (QCD) is studied in a variety of circumstances from both perturbative and non-perturbative perspectives. The main emphasis is on the production and hadronization of heavy particles, specifically heavy quarks, gauge bosons, leptoquarks and supersymmetric particles. READ MORE

4. Axionlike particles, quantum loops, and supernovae : The role of quantum loop corrections for astrophysical ALPs
Abstract : In this thesis the quantum field theory and astrophysical phenomenology of axionlike particles (ALPs) are studied. The effective field theory of ALPs is reviewed with a special focus on quantum loops, the renormalization group equations, and the equivalent forms of the interaction between ALPs and fermions.

5. Nucleon-Induced Fission Cross Sections of Heavy Nuclei in the Intermediate Energy Region
Abstract : Fission is the most important nuclear reaction for society at large today due to its use in energy production. However, this has raised the problem of how to treat the long-lived radioactive waste from nuclear reactors. READ MORE
