1. Twisted Loops and Models for Form-factors and the Muon g-2
Abstract : In this thesis we use effective field thory methods and models for low energy QCD in two different contexts. One is direct calculation of contributions to the anomalous magnetic moment of the muon, muon g-2. The other is estimates of systematic sources of uncertainty in lattice QCD simulations. The work is presented in five papers. READ MORE

2. Loops, Twists and String Vertices: The Sewing Approach to String Perturbation Theory
Abstract : String theory provides the most promising candidate for a unified theory of all fundamental forces and a consistent quantum mechanical theory of gravity. String theory is, at present, defined through its perturbation expansion. There exists various methods for treating the string diagrams one of which is through the sewing of Reggeon vertices.
