Asymptotic Analysis of Multi-scale, Multi-loop Feynman Diagrams
It is very challenging to solve multi-scale, multi-loop Feynman diagrams analytically. The presence of different kinematic scales makes the computation of Feynman diagrams very difficult, sometimes impossible to get the ... -
Direct and Indirect Search for New Physics at Colliders
The Standard Model (SM) of particle physics has been remarkably successful to describe strong, weak and electromagnetic forces of nature, as it has agreed with most of the experiments till date. However, there are still ... -
Feynman Integral Calculus and Hypergeometric Functions: New Results, Interconnections and Computer Algebra
Feynman integrals play a fundamental role in perturbative calculations within the realm of quantum field theory. In this thesis, we study several important mathematical properties of multi-loop multi-leg Feynman Integrals ... -
Some investigations into algebraic and geometric properties of Feynman integrals and related topics
We describe our investigations into various formal properties of Feynman integrals and of scattering amplitudes obtained from studying algebraic structures. There are variety of ways to study these properties. Out of which, ... -
Some investigations into the methods and applications of modern Feynman Integral evaluation
Feynman Integrals appear in perturbative quantum field theories and have been the focus of intensive study for over half a century. With the rise of the Standard Model of particle physics and its various extensions and the ... -
Studies of Feynman and Related Integrals and their Hypergeometric Connection using the Method of Brackets, Algebraic Relations and Singularity Analysis
Feynman integrals are special kind of integrals that arise in perturbative quantum field theory and are often very difficult to evaluate in terms of known functions of mathematical physics. At times some of the methods ...
