Descrizione
Precision measurements of the top quark mass at hadron colliders have been notoriously difficult. Energy-energy correlators (EECs) provide clean access to angular correlations in the hadronic energy flux, but their application to the precision mass measurements is less direct since they measure a dimensionless angular scale.
Inspired by the use of standard candles in cosmology, I will show that a single EEC-based observable can be constructed that reflects the characteristic angular scales of both the $W$-boson and top quark masses. This gives direct access to the dimensionless quantity $m_t/m_W$, from which $m_t$ can be extracted in a well-defined short-distance scheme as a function of the well-known $m_W$ and a purely angular measurement. I will demonstrate several remarkable properties of this observable as well as its statistical feasibility and robustness for the LHC. This proposal provides a road map for a rich program for top mass determination at the LHC with record precision.
