Analytic Computation of three-point energy correlator in QCD

A bstract The energy correlator measures the deposited in multiple detectors as a function of angles among them. In this paper, an analytic formula is given for three-point with full angle dependence at leading order electron-positron annihilation. This first computation trijet event shape observables QCD, which provides valuable data phenomenological studies. result computed direct integration, where appropriate parameterizations both phase space and kinematic are adopted to simplify calculation. With dependence, our expansions various regions such equilateral, triple collinear squeezed limits, benefit studies on factorization large logarithm resummation.
