    Published 2020-01-01
    “…Our result avoids no-go theorems of perturbative stabilisation due to runaway potentials, in a way similar to the Coleman-Weinberg mechanism, and provides a counter example to one of the swampland conjectures concerning de Sitter vacua in quantum grav- ity, once string loop effects are taken into account; it thus paves the way for embedding the Standard Model of particle physics and cosmology in string theory.…”

    Entanglement enabled intensity interferometry in ultrarelativistic ultraperipheral nuclear collisions by James Daniel Brandenburg, Haowu Duan, Zhoudunming Tu, Raju Venugopalan, Zhangbu Xu

    Published 2025-02-01
    “…We propose that a variant of the entanglement enabled intensity interferometry (E^{2}I^{2}) framework introduced by Cotler and Wilczek can provide a powerful alternative to HBT interferometry in extracting fundamental nonperturbative features of quantum chromodynamics at high energies. We apply this framework to demonstrate that the spatial distributions of color singlet (pomeron) configurations in nuclei are sensitive to measurements of exclusive resonant decays of ρ mesons into π^{±} pairs in ultrarelativistic ultraperipheral nuclear collisions (UPCs) at the Relativistic Heavy Ion Collider and the Large Hadron Collider. …”
