  • RHIC

    Brookhaven physicists are using detectors at the Relativistic Heavy Ion Collider to explore how the matter that makes up atomic nuclei behaved just after the Big Bang.


    Brookhaven physicists and engineers are collaborators in the ATLAS experiment at CERN's Large Hadron Collider.

    Presented by George Rupp, Instituto Superior Técnico

    Hosted by: Jin Huang

    The most fundamental cornerstone of the PDG tables is the uniqueness of S-matrix pole positions of unstable particles, as a consequence of quantum-field-theory principles. Therefore, the unitarity property of the S-matrix should ideally be respected in whatever description of meson resonances in experiment, lattice-QCD simulations, and quark models. However, mesons are still often analyzed using non-unitary Breit-Wigner parametrizations and treated as manifest bound states on the lattice or in models. In the present talk I shall demonstrate the huge discrepancies that may result from such naive approaches, with potentially dramatic consequences for meson spectroscopy and the inferred confining potential.

    "Maximizing the potential of neutrino experiments"

    Presented by Philip Rodrigues, University of Oxford

    3 pm, Webcast

    Thursday, April 9, 2020, 3:00 pm

    Hosted by: Hanyu Wei

    Present and future neutrino experiments will search for CP violation in the lepton sector, detect neutrinos from a galactic supernova, and search for evidence of sterile neutrinos. I will discuss two strands of work aimed at maximizing the success of these experiments: on DUNE, developing the far detector trigger system is vital to achieving the physics goals of the experiment; while on the SBN project, neutrino cross section uncertainties are a major systematic in the sterile neutrino oscillation analysis.
