    Several results from the ZEUS Collaboration were presented at this Workshop. The highlights are presented in this summary, and include results from NLO QCD fits and determination of alphas, from forward jets and diffractive final states, from pentaquarks and searches and from heavy flavour production. Also the first results from the analysis of the HERA II e+p/e-p data are shown.Comment: 12 pages, Proceedings of the DIS05 Workshop, Madison, 200

    GRB 090323 and GRB 090328: two long high-energy GRBs detected with Fermi

    Full text link
    We present the analysis of two long Gamma-Ray Bursts, GRB 090323 and GRB 090328, which triggered the Fermi Gamma-Ray Burst Monitor (GBM) and generated an Autonomous Repoint Request to the Fermi Large Area Telescope. The GBM light curves show multi-peaked structures for both events. Here, we present time-integrated and time-resolved burst spectra fitted with different models by the GBM detectors.Comment: 6 pages, 4 figures, 1 table, Proceedings for "The Shocking Universe - Gamma-Ray Bursts and High Energy Shock phenomena", Venice (Italy), September 14-18, 200

    Search for exotic charmonium states

    One of the most intriguing puzzles in hadron spectroscopy are the numerous charmonium-like states observed in the last decade, including charged states that are manifestly exotic. The BABARBABAR and Belle experiments have extensively studied those in B meson decays, initial state radiation processes and two photon reactions. We can question what we have understood after 11 year search in this field, and try to combine results to conclude on what these new unpredicted resonant states are, and how they can be accommodated in the theory. Big effort has been made from theoretical and experimental point of view, as the potential models unlikely explain the presence of so many enhancements, for mass values above the DDˉD \bar D threshold. In this report the BABARBABAR and Belle results of the two invariant mass systems of J/ψϕJ/\psi \phi and J/ψωJ/\psi \omega are put in comparison in a search for non-conventional charmonium states. This involves the study of the systems of J/ψK+KJ/\psi K^+ K^- and J/ψπ+ππ0J/\psi \pi^+ \pi^- \pi^0, respectively. There are strong theoretical arguments in favor of the presence of hybrids or exotic states, in those invariant mass distributions. Remarks on these data analyses are given, based on the BABARBABAR and Belle experimental results.Comment: 8 pages, 21 figures, Proceedings of a plenary talk on behalf of the BaBar and the Belle Collaborations, at the Conference HQL 2014.

    Exotics at Belle and perspectives at Belle II

    Full text link
    The search for multi-quark states beyond the constituent quark model (CQM) has resulted in the discovery of many new exotic states, starting with the observation of the X(3872), discovered by Belle in 2003. Also in the sector of charm-strange physics the CQM does not seem to describe properly all spectrum, despite of theoretical expectations. These new forms of quark bounds clearly show that mesons and baryons are not the only possibilities to be considered. We shortly report in this paper selected recent results on searching for such states at Belle, with the perspectives in the hadron physics program at the Belle II experiment.Comment: 8 pages, 3 figures, proceedings written for the "Excited QCD Workshop 2018", Kopaonik (Serbia
