1. Maximal Unitarity at Two Loops : A New Method for Computing Two-Loop Scattering Amplitudes
Abstract : The study of scattering amplitudes beyond one loop is necessary for precision phenomenology for the Large Hadron Collider and may also provide deeper insights into the theoretical foundations of quantum field theory. In this thesis we develop a new method for computing two-loop amplitudes, based on unitarity rather than Feynman diagrams. READ MORE

2. Effective Field Theory for QCD-like Theories and Constraints on the Two Higgs Doublet Model
Abstract : This thesis includes two topics.The first three papers is the major part of this thesis, which is about higher order calculations in the effective field theories of three QCD-like theories. These three QCD-like theories are distinguished by having quarks in a complex, real or pseudo-real representation of gauge group. READ MORE

3. Hadronization Effects in the Strong Interaction
Abstract : Different hadronization effects in high energy interactions are investigated. The frame-work is the Lund model for the strong interaction. A model for baryon production in jet fragmentation is presented and extended to baryon remnant fragmentation in deep inelastic scattering and hadron--hadron collisions. READ MORE
