Cosmic Bell Test using Random Measurement Settings from High-Redshift Quasars
Dominik Rauch, Johannes Handsteiner, Armin Hochrainer +17
In this Letter, we present a cosmic Bell experiment with polarization-entangled photons, in which measurement settings were determined based on real-time measurements of the wavele…
Inflation on the Brane with Vanishing Gravity
Jason Gallicchio, Rakhi Mahbubani
Many existing models of brane inflation suffer from a steep irreducible gravitational potential between the branes that causes inflation to end too early. Inspired by the fact that…
Quark and Gluon Jet Substructure
Jason Gallicchio, Matthew D. Schwartz
Distinguishing quark-initiated jets from gluon-initiated jets has the potential to significantly improve the reach of many beyond-the-standard model searches at the Large Hadron Co…
Testing Bell's Inequality with Cosmic Photons: Closing the Setting-Independence Loophole
Jason Gallicchio, Andrew S. Friedman, David I. Kaiser
We propose a practical scheme to use photons from causally disconnected cosmic sources to set the detectors in an experimental test of Bell's inequality. In current experiments, wi…
Testing the Weak Equivalence Principle using Optical and Near-Infrared Crab Pulses
Calvin Leung, Beili Hu, Sophia Harris +3
The Weak Equivalence Principle states that the geodesics of a test particle in a gravitational field are independent of the particle's constitution. To constrain violations of the…
Pure Samples of Quark and Gluon Jets at the LHC
Jason Gallicchio, Matthew D. Schwartz
Having pure samples of quark and gluon jets would greatly facilitate the study of jet properties and substructure, with many potential standard model and new physics applications.…
