Free Lecture Explores String Theory and Particle Physics

3/23/2007 —

“String Theory and Particle Physics” is the topic of a lecture at Penn State York Friday, March 23 at 8 p.m. in the Pullo Family Performing Arts Center. The program is sponsored by the American Association of Physics Teachers – Central Pennsylvania Section (AAPT-CPS) and Penn State York. Dr. Mirjam Cvetic, Fay R. and Eugene L. Langberg Professor of Physics, University of Pennsylvania, is the featured speaker. The program is free and open to the public.

Cvetic will review developments leading to the unification of forces within string theory with an emphasis on particle physics implications. She will introduce extended objects – Dirichlet branes and highlight a novel role that these objects play in deriving particle physics from string theory. Cvetic will also discuss progress in finding solutions of string theory with Dirichlet branes that have features of the standard model with three families of quarks and lepons. String theory is a model of fundamental physics whose building blocks are one-dimensional extended objects called strings, rather than the zero-dimensional point particles that form the basis for the Standard Model of particle physics. The phrase is often used as shorthand for Superstring theory.

This lecture is a part of the spring conference of the American Association of Physics Teachers - Central Pennsylvania Section (AAPT-CPS) being held at the campus.
