The Nab project is an experiment at the SNS that will search for new physics beyond the Standard Model via a high-precision measurement of the "a" and "b" neutron decay parameters.
NPDGamma and n3He - the first two experiments at the Spallation Neutron Source (SNS) Fundamental Neutron Physics Beamline (FNPB) - measured parity-violating (PV) asymmetries in neutron capture in light nuclear systems in order to elucidate the weak interaction in hadronic systems.
The High Energy Nuclear Physics Group studies the features of both high temperature and low temperature Quantum Chromo Dynamics (QCD) in strongly interacting matter using ultra high energy collisions of p+p, p+Pb and Pb+Pb at the Large Hadron Collider (LHC) with the A Large Ion Collider Experiment. (ALICE). Presently, the ORNL group leads a large collaboration of U.S. groups conducting a central Barrel Tracking Upgrade (BTU) of the ALICE experiment for a new program of measurements on the Quark Gluon Plasma starting in 2002.
The Large Enriched Germanium Experiment for Neutrinoless Double beta decay (LEGEND) will be the most sensitive search for the ultra-rare phenomena of neutrinoless double-beta decay. Such decays are beyond the “Standard Model” of particle physics, and would have implications for the balance of matter and antimatter in the universe.
