Theoretical Tools

  • Matthew John KirkEmail author
Part of the Springer Theses book series (Springer Theses)


In this chapter we explore some of the concepts, tools and methods which will be used in the rest of the thesis. The idea of effective field theories (EFTs) is one of the most powerful in physics, and we will explain them in Sect. 2.1, along with a specific example of an EFT in Sect. 2.3. Another omnipresent tool is the Heavy Quark Expansion, which we see in Sect. 2.2.
