SUMMARY:Fractal based observables to probe jet substructure of quarks and 
 gluons - Joseph Davighi\, DAMTP\, Cambridge

CONTACT:Dr Maria Ubiali
DESCRIPTION:I will discuss a new class of jet observables\, which are desi
 gned to characterize both fractal and scale-dependent contributions to the
  distribution of hadrons within the jet. These infrared safe observables\,
  which we name Extended Fractal Observables (EFOs)\, have been applied to 
 the important problem of distinguishing quark jets from gluon jets. I shal
 l summarize evidence from parton shower simulations that the inclusion of 
 EFOs improves the performance of existing quark gluon discriminators. More
  generally\, this method of studying jet substructure is a new approach\, 
 and I shall discuss other possible applications in particle physics.
