Large N-point energy correlator in the collinear limit

For the N-point energy correlator in the collinear limit, the largest projected angle R in the large N limit can be viewed as the radius of the jet that encompasses all the collinear core particles, while contributions from soft gluons to the radius are suppressed. We relate the N-point energy correlator in the large N limit to the moments of the fragmentation functions to a jet, and, using previous work, we compare the difference between jets initiated by heavy quarks and light quarks. This comparison demonstrates the dead-cone effect.
