Lawrence Krauss gave a great HEFTI Lecture on Extra Dimensions at UC Davis.  The lecture was based largely on his recent book Hiding in the Mirror: The Mysterious Allure of Extra Dimensions.  He not only explained how mathematics led string theorists to extra dimensions he also delved into the psychology of why human beings like to believe in concepts like extra dimensions.

Hirn and Sanz have examined models of electroweak symmetry breaking in anti-de Sitter space via boundary conditions. They include additional bulk breaking of electroweak symmetry and find that they can change the spectrum of vector and axial vector resonances so as to make the S parameter negative and thus compatible with precision electroweak tests.


Warped Passages

Lisa Randall gave a HEFTI public lecture, based on her recent popular book“Warped Passages” at UC Davis on Jan 10.  While students got in free, the general public paid $7, and the 400 seat ballroom sold out, with about 100 people turned away. Many people were surprised that so many people would pay to hear about cutting edge physics. It seems to be further evidence that the public thinks physics is actually cool, provided that someone will bother to try to explain it in an accessable way.
