We show that known QQ̅ resonances, together with residual soft meson-meson rescattering, saturate the spectra including the exotic J^PC=1^-+ channel. A possibility of a narrow exotic resonance at a mass near 1.6 GeV/c^2 cannot, however, be ruled out.

We present the results of the analysis of 30,740 events in the mass range 1.24--1.60 GeV/c/sup 2/, with 0.0less than or equal to-t<1.0 GeV/sup 2//c/sup 2/. In the 1.28 GeV/c/sup 2/ mass region, we see evidence for a J/sup P//sup G/ = 0/sup - +/ resonance in addition to the resonant 1/sup + +/ wave. We observe a 0/sup - +/ resonance and possibly a small 1/sup + +/ resonance in the 1.42 GeV/c/sup 2/ region. We also observe a 1/sup + +/ state near 1.5 GeV/c/sup 2/.

These interactions are predicted using the three-dimensional structure of the bound complex between each pair of protein and compound that is predicted by molecular docking. These docking runs consist of millions of individual short jobs each lasting only minutes. However, computing resources to execute these jobs (which cumulatively take tens of millions of CPU hours) are not readily or easily available in a cost effective manner. By looking to National Cyberinfrastructure resources, and specifically the Open Science Grid (OSG), we have been able to harness CPU power for researchers at the Indiana University School of Medicine to provide a quick and efficient solution to their unmet computing needs. Using the job submission infrastructure provided by the OSG, the docking data and simulation executable was sent to more than 100 universities and research centers worldwide. These opportunistic resources provided millions of CPU hours in a matter of days, greatly reducing time docking simulation time for the research group. The overall impact of this approach allows researchers to identify small molecule candidates for individual proteins, or new protein targets for existing FDA-approved drugs and biologically active compounds.

In 2012, OSG added a new focus area in networking with a goal of becoming the primary source of network information for its members and collaborators. This includes gathering, organizing, and providing network metrics to guarantee effective network usage and prompt detection and resolution of any network issues, including connection failures, congestion, and traffic routing. In September of 2015, this service was deployed into the OSG production environment. We will report on the creation, implementation, testing, and deployment of the OSG Networking Service. Starting from organizing the deployment of perfSONAR toolkits within OSG and its partners, to the challenges of orchestrating regular testing between sites, to reliably gathering the resulting network metrics and making them available for users, virtual organizations, and higher level services, all aspects of implementation will be reviewed. In particular, several higher-level services were developed to bring the OSG network service to its full potential. These include a web-based mesh configuration system, which allows central scheduling and management of all the network tests performed by the instances; a set of probes to continually gather metrics from the remote instances and publish it to different sources; a central network datastore (esmond), which provides interfaces to access the network monitoring information in close to real time and historically (up to a year) giving the state of the tests; and a perfSONAR infrastructure monitor system, ensuring the current perfSONAR instances are correctly configured and operating as intended. We will also describe the challenges we encountered in ongoing operations of the network service and how we have evolved our procedures to address those challenges. Finally we will describe our plans for future extensions and improvements to the service.

The current detector concept was generated by several design constraints. Since the highest energy beams will not be immediately available the detector must be designed to be useful (or scalable) over a range of energies. A general purpose detector should be able to measure charged particle momenta with very good acceptance and resolution. This implies a magnetic spectrometer, the design of which is non-trivial given the very high desired beam rates and the correspondingly high e{sup +}e{sup -} pair rates. Identification of charged particle species ({pi}/K/p separation) is also desirable. Photon detection, to identify final states with one or more {pi}{sup 0}, {eta} or {omega} mesons, is also clearly essential. Each of these issues is addressed.

The reaction p ! 0 0 n may be used to examine both scalar and tensor mesons.

Photons from meson decays were detected with a lead-glass calorimeter with an energy resolution of 11% at 1 GeV. Various veto and trigger components were also present. Final states with as many as six photons were successfully detected and reconstructed.

These are presented in approximately chronological order: Stanford Linear Accelerator Lab (CA) analysis on the experiment. Three students completed their theses this reporting period. The group was a collaborator in the Mark I1 experiment at the SLC and completed e Fern' National Accelerator Lab (IL) now in its final data collection period. Our group is also a collaborator in the DO collider experiment which is now preparing for the first data run in 1992. The group is the prime mover in (E672), a high mass dimuon experiment which CERN (Geneva, Switzerland) data. The group also is working on the development of a major offline facility shift and on a silicon vertex chamber for 1993. The group is a collaborator in the OPAL experiment at LEP which is now taking Brookhaven National Laboratory (NY) in precision meson spectroscopy. A test run is presently underway and data taking will begin in 1993. The group is the prime mover in the construction of a major new experiment (E852)

This analysis is based on 3.0M π − π 0 π 0 events and 2.6M π − π − π + events and shows production of the a2(1320), π2(1670) and π(1800) mesons. An earlier analysis of 250K π − π − π + events from the same experiment showed possible evidence for a J P C = 1 −+ exotic meson with a mass of 1.6 GeV/c 2 decaying into ρπ. In this analysis of a higher statistics sample of the (3π) − system in two charged modes we find no evidence of an exotic meson.

The events were collected using the large-acceptance Fermilab multiparticle spectrometer. The fraction of events that are planar when a full-azimuthal-acceptance trigger is used does not increase with transverse energy. However, when additional requirements are applied to the data such as restricting the azimuth

The gas consists of neutrons, protons, alpha particles, and 8980 species of nuclei with A ≥ 12 and masses from the finite-range droplet model (FRDM). At very low density, the Virial expansion reduces to nuclear statistical equilibrium. At higher density, the Virial results match smoothly to the relativistic mean field results discussed in our previous paper. We tabulate the resulting EOS at over 73,000 grid points in the temperature range T = 0.158 to 15.8 MeV, the density range nB = 10 −8 to 0.1 fm −3 , and the proton fraction range YP = 0.05 to 0.56. In the future we plan to match these low density results to our earlier high density mean field results, and generate a full EOS table for use in supernova and neutron star merger simulations. This Virial EOS is exact in the low density limit.
