Symmetrized tower $p_{\text{T}}$ distribution projections in $\mathit{\varphi }$ for an example a hard-scatter jet and b stochastic pile-up jet in simulated $t\overline{t}$ events. The black histogram line corresponds to the projection of the 2D tower distribution. The fit model closely follows the hard-scatter jet distribution, yielding a large Gaussian signal, while stochastic pile-up jets feature multiple smaller signals, away from the jet core
