Applying Quantum Entanglement to Search for New Physics at TeV Energies

Roney Collisions of electrons and positrons can create B meson particles in an entangled state. I will explain how the BABAR experiment, based in California, has applied the associated Einstein–Podolsky– Rosen effect to study differences between matter and antimatter known as CP violation, as well as how it has used the effect to observe the “quantum arrow of time”. The Belle II/SuperKEKB facility that is currently being commissioned in Japan will extend these studies and will be sensitive to new physics at energies well above those available at CERN’s Large Hadron Collider (LHC) in Geneva. I will describe how it will do so and discuss the hint for new physics published by BABAR that has been supported by recently reported measurements at the Belle and LHCb experiments.
