Physics Colloquium

"Magnetic Monopoles: The Unicorns of Physics"

Presented by Alfred Scharf Goldhaber, Stony Brook University

Tuesday, April 10, 2007, 3:30 pm — Large Seminar Room, Bldg. 510

Like unicorns in legend and art, monopoles have one of something where ordinary counterparts have two. In both cases there is great beauty in this "one-ness," and there are detailed ideas about the nature of such objects. The existence of monopoles would imply very tight constraints on the structure of physics, and this talk is a look at some of the ways monopoles would fit, or not, with other facts we think we know. In particular, the standard model of electroweak and strong interactions implies a rather high minimum value for the mass of a monopole. This takes nothing away from the value of experimental searches for these rare creatures, but gives reason to suspect that accelerator production of monopoles may not be easy to achieve.
