SUMMARY:Quantum Gravity and the Standard Model
DESCRIPTION:Featuring Lee Smolin\, Perimeter Institute\, Canada\nHosted by:
	 John Stachel\n\nPart of the Physics Department Colloquia Series.\n\nI desc
	ribe recent progress in background independent quantum theories of gravity.
	  These are theories whose formulation requires no classical metric or fie
	lds and no global symmetries. The presentation begins with an introduction
	 to the basic ideas\, hypotheses and results of loop quantum gravity and re
	lated models of quantum spacetime.  I first review how such models may be 
	tested by upcoming experiments that test Poincare invariance at Planck scal
	es.  I then describe recent work by Markopoulou and Kribs based on the app
	lication of methods from quantum information theory which shows that a larg
	e class of these models have emergent degrees of freedom that carry conserv
	ed quantum numbers not related to general relativity.  In one class of suc
	h models the simplest such emergent excitations can be mapped to a composit
	e model of the quarks and leptons.
