Top Jets

A set of studies involving the truth matching performance of jets and truth children (if the originating top is leptonic). The aim is to investigate the resolution of the formed invariant top-mass when using the jet container, followed by their respective kinematics and parton content.

Figure 8.a

../../../../_images/Figure.8.a.png

The figure illustrates the formed invariant mass of the top-quark from jets being matched to individual tops by index. The underlying distribution is partitioned into whether a given top has decayed leptonically or hadronically. For leptonically decaying tops, truth children (lepton and neutrino) are used from the associated parent top.

Figure 8.b

../../../../_images/Figure.8.b.png

The figure illustrates the formed invariant mass of the top-quark from jets being matched to individual tops decaying leptonically. The underlying distribution is partitioned into the number of jet contributions. For this matching scheme the truth children are used to add the missing the neutrinos and leptons.

Figure 8.c

The figure illustrates the formed invariant mass of the top-quark from jets being matched to individual tops decaying hadronically. The underlying distribution is partitioned into the number of jet contributions.

Figure 8.d

../../../../_images/Figure.8.d.png

The figure illustrates the formed invariant mass of the top-quark from jets being matched to individual tops decaying leptonically. The underlying distribution is partitioned into the number of tops contributing to a given matched jet. This plot aims to illustrate cases, where a jet can be shared between adjacent tops. For this matching scheme the truth children are used to add the missing the neutrinos and leptons.

Figure 8.e

The figure illustrates the formed invariant mass of the top-quark from jets being matched to individual tops decaying hadronically. The underlying distribution is partitioned into the number of tops contributing to a given matched jet. This plot aims to illustrate cases, where a jet can be shared between adjacent tops.

Figure 8.f

../../../../_images/Figure.8.f.png

A figure depicting the \Delta R between Jets originating from a common Top-Quark compared to other, non-Top based, Jets. The different distributions in the figure indicate whether the given jet originates from a spectator or resonance top, and how this top decayed. For background entries, the other jet is not allowed to originate from the same Top-Quark however, the other Jet can also originate from a different Top-Quark.
