The combination of greater rumen fiber and starch fermentability of the new hybrid resulted in greater efficiency of solids-corrected milk production and milk nitrogen efficiency compared with the brown midrib and conventional hybrids

    Inclusive K+K^+ and exclusive K+YK^+Y photoproduction on the deuteron: Λ\Lambda- and Σ\Sigma-threshold phenomena

    Full text link
    Inclusive K+K^+ and exclusive K+YK^+Y photoproduction on the deuteron are investigated theoretically. Modern hyperon-nucleon forces and a recently updated kaon photoproduction operator for the γ+NK++Y\gamma +N\to K^++Y process are used. Sizable effects of the hyperon-nucleon final state interaction are found near the K+ΛNK^+\Lambda N and K+ΣNK^+\Sigma N thresholds in the inclusive reaction. Angular distributions for the exclusive process show clear YNYN final state interaction effects in certain kinematic regions. Precise data especially for the inclusive process around the K+ΣNK^+\Sigma N threshold would help to clarify the strength and property of the ΛNΣN\Lambda N-\Sigma N interaction.Comment: 14 pages, 10 figure

    Photoproduction of scalar mesons on protons and nuclei

    We study the photoproduction of scalar mesons close to the threshold of f_0(980) and a_0(980) using a unitary chiral model. Peaks for both resonances show up in the invariant mass distributions of pairs of pseudoscalar mesons. A discussion is made on the photoproduction of these resonances in nuclei, which can shed light on their nature, a subject of continuous debate.Comment: 25 pages, 9 figures, accepted for publication in Phys Rev

    QCD and strongly coupled gauge theories : challenges and perspectives

    Get PDF
    We highlight the progress, current status, and open challenges of QCD-driven physics, in theory and in experiment. We discuss how the strong interaction is intimately connected to a broad sweep of physical problems, in settings ranging from astrophysics and cosmology to strongly coupled, complex systems in particle and condensed-matter physics, as well as to searches for physics beyond the Standard Model. We also discuss how success in describing the strong interaction impacts other fields, and, in turn, how such subjects can impact studies of the strong interaction. In the course of the work we offer a perspective on the many research streams which flow into and out of QCD, as well as a vision for future developments.Peer reviewe
