BaBar's Hunt for an Exotic Higgs Boson

The BaBar collaboration submitted two papers to Physical Review Letters last month, both searching for hypothetical light-mass Higgs bosons—the particles suspected of giving objects their mass. While the Large Hadron Collider at CERN will search for a heavy-mass Higgs that lies outside the BaBar experiment's energy range, other theories predict another, lighter Higgs within BaBar's reach. Both papers found no evidence of a low-mass Higgs in the BaBar data set.

"While it would have been very exciting to find a low-mass Higgs, the BaBar results are still important for the particle physics community," says Yury Kolomensky of U.C. Berkeley and Lawrence Berkeley National Laboratory. "A negative result can rule out some Higgs theories, which is positive progress. If and when the Higgs is discovered, we will need to understand the underlying theory. Do we live in a world where a single Higgs boson is responsible for the generation of the mass of all particles, or is there more variety in nature?"  Read more...

Welcome to SLAC!

First HR Roundtable Today at Noon

All are invited to stop by the Human Resources Noon Hour Roundtable at the Linear Café, today from noon to 1 p.m. Representatives from the HR Department will be available for any questions you may have. Don't have time to stop by at lunch today? Future HR Roundtables are scheduled through the month of July:

Thursday, July 16
Tuesday, July 21
Thursday, July 30

Contact Vivian Lee (x4077) with any questions about the roundtables.
