Search for CPT and lorentz violation in B(0)-(B)over-bar(0) oscillations with dilepton events
We report results of a search for CPT and Lorentz violation in B0-B0 oscillations using inclusive dilepton events from 232106 Î¥(4S)BB decays recorded by the BABAR detector at the PEP-II B Factory at SLAC. We find 2.8Ï significance, compatible with no signal, for variations in the complex CPT violat...

| description | We report results of a search for CPT and Lorentz violation in B0-B0 oscillations using inclusive dilepton events from 232106 Î¥(4S)BB decays recorded by the BABAR detector at the PEP-II B Factory at SLAC. We find 2.8Ï significance, compatible with no signal, for variations in the complex CPT violation parameter z at the Earths sidereal frequency and extract values for the quantities Î"aÎ in the general Lorentz-violating standard-model extension. The spectral powers for variations in z over the frequency range 0.26yr-1 to 2.1solarday-1 are also compatible with no signal. © 2008 The American Physical Society. |
