Description
A precise and well-defined top quark mass measurement is essential for electroweak fits and vacuum stability studies, and is a prerequisite for the precision program of future colliders. In this talk, I will present the three-point energy correlator (EEEC) as a new probe of top quark decay, with the goal of achieving a theoretically controlled mass determination.
Heavy unstable particles leave a distinctive imprint in energy correlators: their mass introduces an angular scale, producing a sharp peak in the distribution that can be understood as a boosted Sudakov effect.
Within the framework of SCET and HQET, I will derive a factorization theorem for describing the singular region of the EEEC measured on boosted top jets arising from the three-pronged hadronic top decay. I will present the one-loop results for the factorization functions that include a novel, multi-Wilson line soft function, and outline the upcoming steps towards achieving the complete EEEC spectrum.
