``BaBar's New Physics Search with Gluonic Penguins''

Gluonic Penguin B-decays present a promising approach to search for new quark-flavor generations beyond the Standard Model of particle physics. In neutral B-meson decays into final states such as h' K⁰ and j K⁰ they potentially show up as distortions of CP asymmetries with small theoretical uncertainties. The BaBar experiment has now accumulated more than 340 million B B pairs produced by electron-positron annihilation at the U(4S) resonance at the PeP-II asymmetric-energy B-meson Factory of SLAC that allow significant CP measurements in the rare gluonic penguin decays. Recent results on this search will be presented.

Refreshments will be served in CP 179 at 3:15 PM
