Probing the Gauge Content of Heavy Resonances with Soft Radiation

Sung, Ilmo

Understand

The use of energy flow is investigated as a diagnostic tool for determining the color SU(3) representation of new resonances.

  • It is found that the pattern of soft gluon radiation into a rapidity gap depends on color flow in the hard scattering, and reflects the gauge content of new physics.
  • The massive soft anomalous dimension matrix for rapidity gap events is introduced for describing soft gluon emission analytically in heavy quark pair production.
  • A gap fraction is used for quantifying the amount of soft radiation into the gap region.
