On the Angular Resolution of Pair-Conversion -Ray Telescopes

Denis Bernard

I present a study of the several contributions to the single-photon angular resolution of pair telescopes in the MeV energy range. I examine some test cases, the presently active {…

Search for Mesogenesis at BABAR

BABAR Collaboration, J. P. Lees, V. Poireau +239

A new mechanism has been proposed to simultaneously explain the presence of dark matter and the matter-antimatter asymmetry in the universe. This scenario predicts exotic meson…

MeV-GeV Polarimetry with : Asserting the Performance of Silicon Strip Detectors-Based Telescopes

Denis Bernard

The polarimetry of gamma rays converting to an pair would open a new window on the high-energy gamma-ray sky by, among other things, providing insight into the radiation m…

Search for an Axion-Like Particle in B Meson Decays

The BABAR Collaboration

Axion-like particles (ALPs) are predicted in many extensions of the Standard Model, and their masses can naturally be well below the electroweak scale. In the presence of couplings…

Search for Lepton Flavor Violation in

BABAR Collaboration

We report on the first search for electron-muon lepton flavor violation (LFV) in the decay of a ~quark and ~antiquark bound state. We look for the LFV decay $Υ(3S)\rightarrow…

Search for Darkonium in Collisions

The BABAR Collaboration

Collider searches for dark sectors, new particles interacting only feebly with ordinary matter, have largely focused on identifying signatures of new mediators, leaving much of dar…
