Probing Local Charm Hadronization Dynamics with Hadron-Anchored Energy Correlators
Abstract
We introduce the hadron-anchored energy correlator (HAEC), a jet-restricted realization of the fragmentation energy correlator and the semi-inclusive energy correlator frameworks, and apply it to heavy-flavor-tagged jets in hadron collisions. Using \textsc{Pythia}~8 simulations of D0- and Λc+-tagged jets, we find a pronounced, localized suppression of energy flow around the Λc+ relative to the D0, followed by a sharp transition scaling as θ0∝1/pTjet with little tune dependence. The conventional jet-axis radial profile shows qualitatively different color-reconnection dependence, suggesting reduced sensitivity of HAEC to jet-axis effects. A beauty-sector study can distinguish a heavy-quark-mass origin from a local fragmentation-vertex origin.

AB - We introduce the hadron-anchored energy correlator (HAEC), a jet-restricted realization of the fragmentation energy correlator and the semi-inclusive energy correlator frameworks, and apply it to heavy-flavor-tagged jets in hadron collisions. Using \textsc{Pythia}~8 simulations of D^0- and Λ_c^+-tagged jets, we find a pronounced, localized suppression of energy flow around the Λ_c^+ relative to the D^0, followed by a sharp transition scaling as θ_0∝1/p_T^jet with little tune dependence. The conventional jet-axis radial profile shows qualitatively different color-reconnection dependence, suggesting reduced sensitivity of HAEC to jet-axis effects. A beauty-sector study can distinguish a heavy-quark-mass origin from a local fragmentation-vertex origin.
