Description
Energy-Energy Correlation (EEC) in electron-positron
annihilation into hadrons at high energy, gives the distribution
of the angular distance between hadronic jets in the final state.
The measure is usually inclusive over quark flavors,
implying that also beauty (charm) quark Correlations
are included. Given the great accuracy reached in both
experimental and present theoretical (perturbative) calculations,
the inclusion of beauty mass effects is highly recommended.
We present a simple formalism to consistently include
heavy-quark mass effects in the Energy-Energy Correlation
in the two-jet region, dominated by large Sudakov logarithms
which need to be resummed to all orders of perturbation theory.
