WFU Physics Colloquium

Fifth Annual Alumni Colloquium

TITLE: Could Dark Matter Come from Extra Dimensions?

SPEAKERS: Dr. Andrew Frey,and Rebecca Danos,

Department of Physics
McGill University

TIME: Friday Oct. 9, 2009 at 4:00 PM

PLACE: George P. Williams, Jr. Lecture Hall, (Olin 101)

Refreshments will be served at 3:30 PM in the lounge. All interested persons are cordially invited to attend.

Several years ago, Chandran Sabanayagam (BA-MS WFU 1993) started the Alumni Colloquium series. This year, we are very pleased to have Andrew Frey (BS WFU 1998 with Honors) and his wife Rebecca Danos, as our speakers.

ABSTRACT

Strong observational evidence tells us that most of the matter in the universe is invisible and, even more, not made out of Standard Model particles. Some models of extra dimensions in string theory contain natural candidates for the dark matter particle; we will describe these heavy particles and calculate their lifetimes. Amazingly, in some models, the decays of these particles could be observable, which would give us a way to constrain extra-dimensional physics.
