Search for hadronic decays of a light Higgs boson in the radiative decay Upsilon --> gamma A0
The BABAR Collaboration, J. P. Lees, V. Poireau +385
We search for hadronic decays of a light Higgs boson (A0) produced in radiative decays of an Upsilon(2S) or Upsilon(3S) meson, Upsilon --> gamma A0. The data have been recorded by…
Evidence for the decay B0 --> omega omega and search for B0 --> omega phi
The BABAR Collaboration, J. P. Lees, V. Poireau +333
We describe searches for B meson decays to the charmless vector-vector final states omega omega and omega phi with 471 x 10^6 B Bbar pairs produced in e+ e- annihilation at sqrt(s)…
Study of radiative bottomonium transitions using converted photons
The BABAR Collaboration, J. P. Lees, V. Poireau +388
We use 111+/-1 million Upsilon(3S) and 89+/-1 million Upsilon(2S) events recorded by the BaBar detector at the PEP-II B-factory at SLAC to perform a study of radiative transitions…
Production and Integration of the ATLAS Insertable B-Layer
B. Abbott, J. Albert, F. Alberti +373
During the shutdown of the CERN Large Hadron Collider in 2013-2014, an additional pixel layer was installed between the existing Pixel detector of the ATLAS experiment and a new, s…
The Physics of the B Factories
A. J. Bevan, B. Golob, Th. Mannel +2003
This work is on the Physics of the B Factories. Part A of this book contains a brief description of the SLAC and KEK B Factories as well as their detectors, BaBar and Belle, and da…

The BABAR Collaboration, J. P. Lees, V. Poireau +384
We report the observation of the baryonic B decay B0bar --> Lambda_c^+ anti-Lambda K- with a significance larger than 7 standard deviations based on 471x10^6$ BBbar pairs collected…
Observation of Time Reversal Violation in the B0 Meson System
The BABAR Collaboration, J. P. Lees, V. Poireau +364
Although CP violation in the B meson system has been well established by the B factories, there has been no direct observation of time reversal violation. The decays of entangled n…
