Title: Predictions for energy correlators probing substructure of groomed heavy quark jets

Abstract

We develop an effective field theory (EFT) framework to perform an analytic calculation for energy correlator observables computed on groomed heavy-quark jets. A soft-drop grooming algorithm is applied to a jet initiated by a massive quark to minimize soft contamination effects such as pile-up and multi-parton interactions. We specifically consider the two-particle energy correlator as an initial application of this EFT framework to compute heavy quark jet substructure. We find that there are different regimes for the event shapes, depending on the size of the measured correlator observable, that require the use of different EFT formulations, in which the quark mass and grooming parameters may be relevant or not. We use the EFT to resum large logarithms in the energy correlator observable in terms of the momentum of a reconstructed heavy hadron to NLL' accuracy and subsequently match it to a full QCD O(αs) cross section, which we also compute. We compare our predictions to simulations in Pythia for e+e– collisions. We find a good agreement with partonic simulations, as well as hadronic ones with an appropriate shape function used to describe nonperturbative effects and the heavy quark hadron decay turned off. We also predict the scaling behavior for themore » leading nonperturbative power correction due to hadronization. Consequently, we can give a prediction for the energy correlator distribution at the level of the reconstructed heavy hadron. This work provides a general framework for the analysis of heavy quark jet substructure observables.« less

Figure 1 Figure 1: Phase space inmore » $z$, $θ$ and associated modes in the singular limit. The allowed phase space is determined by imposing the soft drop cut on the energy $z$cut < $z$, and the limit on the angle $θ$ imposed by the jet radius, $θ$ < $R$ and the finite quark mass $θ$ > $θ$ min = $m$/$E$J . Lines of constant e$^{(α)}_{2}$ given by eq. (3.2) are shown at several values of e$^{(α)}_{2}$ . The light dotted line is the minimum value e$^{(α)}_{2,min}$, in eq. (3.6). The first dashed line at e$^{(α)}_{2(i)}$ represents a small value where the cross section is sensitive both to the quark mass and to grooming. The second dashed line at e$^{(α)}_{2(FO)}$ represents a larger value where the cross section is not sensitive to quark mass or grooming and has to computed in fixed-order perturbation theory in full QCD (the exact shape of the phase space boundaries at larger $z$, $θ$ will also have to be taken into account, see section 5). Note that this plot is made for the case $α$ = ½ < 1. (See figure 2 for the case $α$ > 1.) At e$^{(α)}_{2,min}$, the collinear-soft and ultracollinear modes merge back into a single-scale, soft drop-sensitive ultracollinear mode ($B$$^{SD}_{+}$ ). The relevant regions for the global soft function SG, the hard function $σ$0, and the matching coefficient $H$+ to bHQET are also illustrated.« less
