Simple Analysis of IR Singularities at One Loop
Ambresh Shivaji
In this article, we explore the structure of IR singularity of Feynman diagrams at one loop via power counting in loop momentum. The emphasis is on many known results which follow…

A Note on the IR Finiteness of Fermion Loop Diagrams
Ambresh Shivaji
We show that the most general fermion loop diagram is finite in both soft and collinear regions and therefore, it's IR finite. We use this result to express the IR singular structu…
