    Hadrons and Nuclei

    William Detmold🇺🇸 · Robert G. Edwards🇺🇸 · Jozef J. Dudek🇺🇸 · Michael Engelhardt🇺🇸 · Huey-Wen Lin🇺🇸 · Stefan Meinel🇺🇸 · Kostas Orginos🇺🇸 · Phiala Shanahan🇺🇸

    This document is one of a series of whitepapers from the USQCD collaboration. Here, we discuss opportunities for lattice QCD calculations related to the structure and spectroscopy of hadrons and nuclei. An overview of recent lattice calculations of the structure of the proton and other hadrons is presented along with prospects for future extensions. Progress and prospects of hadronic spectroscopy and the study of resonances in the light, strange and heavy quark sectors is summarized. Finally, recent advances in the study of light nuclei from lattice QCD are addressed, and the scope of future investigations that are currently envisioned is outlined.

    The Nucleosynthesis and Reaction Rates of Fluorine 19 () in the Sun

    Mohammad K. Mardini · Nidal Ershiadat · Mashhoor A. Al-Wardat · Ali A. Taani · Sergen Ozdemir · Hamid Al-Naimiy · Awni Khasawneh

    We investigate the abundance of in the Sun through the nucleosynthesis scenario. In addition, we calculate the rate equations and reaction rates of the nucleosynthesis of at different temperature scale. Other important functions of this nucleosynthesis (nuclear partition function and statistical equilibrium conditions) are also obtained. The resulting stability of occurs at nucleus with A = 19 and Mass Excess= -1.4874 MeV. As a result, this will tend to a series of neutron captures and beta-decay until is produced. The reaction rate of (, ) was dominated by the contribution of three low-energy resonances, which enhanced the final abundance in the envelope.

    The Role of Lattice QCD in Searches for Violations of Fundamental Symmetries and Signals for New Physics

    Vincenzo Cirigliano🇺🇸 · Zohreh Davoudi🇺🇸 · Tanmoy Bhattacharya🇺🇸 · Taku Izubuchi🇺🇸 · Phiala E. Shanahan🇺🇸 · Sergey Syritsyn🇺🇸 · Michael L. Wagman🇺🇸

    This document is one of a series of whitepapers from the USQCD collaboration. Here, we discuss opportunities for Lattice Quantum Chromodynamics (LQCD) in the research frontier in fundamental symmetries and signals for new physics. LQCD, in synergy with effective field theories and nuclear many-body studies, provides theoretical support to ongoing and planned experimental programs in searches for electric dipole moments of the nucleon, nuclei and atoms, decay of the proton, - oscillations, neutrinoless double- decay of a nucleus, conversion of muon to electron, precision measurements of weak decays of the nucleon and of nuclei, precision isotope-shift spectroscopy, as well as direct dark matter detection experiments using nuclear targets. This whitepaper details the objectives of the LQCD program in the area of Fundamental Symmetries within the USQCD collaboration, identifies priorities that can be addressed within the next five years, and elaborates on the areas that will likely demand a high degree of innovation in both numerical and analytical frontiers of the LQCD research.

    Observability of sharp phase transitions in neutron stars

    Sophia Han🇺🇸

    With central densities as high as 5-10 times the nuclear saturation density, neutron stars exhibit extreme conditions that cannot be observed elsewhere. They are ideal astrophysical laboratories for probing the composition and properties of cold, ultra-dense matter. We shall discuss taking into account currently available data from observation, how to reveal possible sharp phase transitions in dense neutron star cores.

    Lattice QCD and Neutrino-Nucleus Scattering

    Andreas S. Kronfeld🇺🇸 · David G. Richards🇺🇸 · William Detmold🇺🇸 · Rajan Gupta🇺🇸 · Huey-Wen Lin🇺🇸 · Keh-Fei Liu🇺🇸 · Aaron S. Meyer🇺🇸 · Raza Sufian🇺🇸 · Sergey Syritsin🇺🇸

    This document is one of a series of whitepapers from the USQCD collaboration. Here, we discuss opportunities for lattice QCD in neutrino-oscillation physics, which inevitably entails nucleon and nuclear structure. In addition to discussing pertinent lattice-QCD calculations of nucleon and nuclear matrix elements, the interplay with models of nuclei is discussed. This program of lattice- QCD calculations is relevant to current and upcoming neutrino experiments, becoming increasingly important on the timescale of LBNF/DUNE and HyperK.
