Two-prong taggers aim at discriminating massive objects that decay into two hard QCD partons (usually quarks), from the background of QCD jets. This signal is often an electroweak boson (H/W/Z) but it can also be a new particle (see Chap. 10 for examples). Our goal in this chapter is two-folded and it closely follows what was done in the previous chapter for quark-gluon tagging. First, we want to give a brief insight into analytic properties of two-prong taggers, mainly selecting a few representative substructure tools and comparing their behaviour in Monte Carlo simulations with analytic results. Then, we will perform a comparative Monte Carlo study of the taggers discriminating properties, assessing both their performance and their resilience against non-perturbative effects.
