A microscopic model for an emergent cosmological constant
Alejandro Perez, Daniel Sudarsky, James D. Bjorken
The value of the cosmological constant is explained in terms of a noisy diffusion of energy from the low energy particle physics degrees of freedom to the fundamental Planckian gra…
Dark Sectors 2016 Workshop: Community Report
Jim Alexander, Marco Battaglieri, Bertrand Echenard +201
This report, based on the Dark Sectors workshop at SLAC in April 2016, summarizes the scientific importance of searches for dark sector dark matter and forces at masses beneath the…
Possible multiparticle ridge-like correlations in very high multiplicity proton-proton collisions
James D. Bjorken, Stanley J. Brodsky, Alfred Scharff Goldhaber
The CMS collaboration at the LHC has reported a remarkable and unexpected phenomenon in very high-multiplicity high energy proton-proton collisions: a positive correlation between…
Emergent Photons and Gravitons:The Problem of Vacuum Structure
J. D. Bjorken
We discuss vacuum condensates associated with emergent QED and with torsion, as well as the possible role of the Kodama wave function in quantum cosmology.
New Fixed-Target Experiments to Search for Dark Gauge Forces
James D. Bjorken, Rouven Essig, Philip Schuster +1
Fixed-target experiments are ideally suited for discovering new MeV-GeV mass U(1) gauge bosons through their kinetic mixing with the photon. In this paper, we identify the producti…
Finite cosmology and a CMB cold spot
R. J. Adler, J. D. Bjorken, J. M. Overduin
The standard cosmological model posits a spatially flat universe of infinite extent. However, no observation, even in principle, could verify that the matter extends to infinity. I…
