SUMMARY:Precision Comparison of the Proton and Antiproton Magnetic Moments 
	in a Penning Trap"
DESCRIPTION:Featuring Mason Marshall\, Harvard University\n\nPart of the HE
	E Seminar Series.\n\nInvariance under the simultaneous action of charge con
	jugation\, parity inversion\, and time reversal (CPT) is a fundamental feat
	ure of the Standard Model.  However\, physics beyond the Standard Model is 
	required to explain basic features of the universe\, including matter-antim
	atter asymmetry.  A precise comparison of the properties of matter-antimatt
	er partners represents a direct laboratory test of CPT invariance.  At Harv
	ard\, Northwestern\, and the CERN Antiproton Decelerator (AD)\, our effort 
	is underway to precisely compare the magnetic moments of a single proton or
	 antiproton in a Penning trap\, as a test of CPT invariance in the baryon s
	ector.  Recent improvements to our Penning trap methods have opened the doo
	r to a sub-PPB comparison.  In this talk I will describe the methods and mo
	tivations for a Penning trap magnetic moment measurement; the ongoing work 
	at the AD; and the current status of the next-generation experimental effor
	t at Harvard.
