Abstract

We have searched for correlations between the pointing directions of ultrahigh energy cosmic rays observed by the High Resolution Fly's Eye experiment and Active Galactic Nuclei (AGN) visible from its northern hemisphere location. No correlations, other than random correlations, have been found. We report our results using search parameters prescribed by the Pierre Auger collaboration. Using these parameters, the Auger collaboration concludes that a positive correlation exists for sources visible to their southern hemisphere location. We also describe results using two methods for determining the chance probability of correlations: one in which a hypothesis is formed from scanning one half of the data and tested on the second half, and another which involves a scan over the entire data set. The most significant correlation found occurred with a chance probability of 24%., Comment: 13 pages, 1 table, 5 figures

Abstract

Air-fluorescence detectors such as the High Resolution Fly's Eye (HiRes) detector are very sensitive to upward-going, Earth-skimming ultrahigh energy electron-neutrino-induced showers. This is due to the relatively large interaction cross sections of these high-energy neutrinos and to the Landau-Pomeranchuk-Migdal (LPM) effect. The LPM effect causes a significant decrease in the cross sections for bremsstrahlung and pair production, allowing charged-current electron-neutrino-induced showers occurring deep in the Earth's crust to be detectable as they exit the Earth into the atmosphere. A search for upward-going neutrino-induced showers in the HiRes-II monocular dataset has yielded a null result. From an LPM calculation of the energy spectrum of charged particles as a function of primary energy and depth for electron-induced showers in rock, we calculate the shape of the resulting profile of these showers in air. We describe a full detector Monte Carlo simulation to determine the detector response to upward-going electron-neutrino-induced cascades and present an upper limit on the flux of electron-neutrinos., Comment: 13 pages, 3 figures. submitted to Astrophysical Journal

Abstract

We report the results of a high-statistics, sensitive search for narrow baryon resonances decaying to $\Xi^-\pi^-$, $\Xi^-\pi^+$, $\bar{\Xi}^+\pi^-$, and $\bar{\Xi}^+\pi^+$. The only resonances observed are the well known $\Xi^0(1530)$ and $\bar{\Xi^0}(1530)$. No evidence is found for a state near 1862 MeV, previously reported by NA49\cite{NA49}. At the 95% confidence level, we find the upper limit for the production of a Gaussian enhancement with $\sigma=7.6$ MeV in the $\Xi^-\pi^-$ effective mass spectrum to be 0.3% of the number of observed $\Xi^0(1530)\to\Xi^-\pi^+$. We find similarly restrictive upper limits for an enhancement at 1862 MeV in the $\Xi^-\pi^+$, $\bar{\Xi}^+\pi^-$, and $\bar{\Xi}^+\pi^+$ mass spectra., Comment: Submitted to PRL

Abstract

We study the spectrum and average mass composition of cosmic rays with primary energies between 10^{17} eV and 10^{18} eV using a hybrid detector consisting of the High Resolution Fly's Eye (HiRes) prototype and the MIA muon array. Measurements have been made of the change in the depth of shower maximum as a function of energy. A complete Monte Carlo simulation of the detector response and comparisons with shower simulations leads to the conclusion that the cosmic ray intensity is changing f rom a heavier to a lighter composition in this energy range. The spectrum is consistent with earlier Fly's Eye measurements and supports the previously found steepening near 4 \times 10^{17} eV ., Comment: 39 pages, 15 figures, in revtex4 epsf style, submited to APJ

Abstract

The average mass composition of cosmic rays with primary energies between $10^{17}$eV and $10^{18}$eV has been studied using a hybrid detector consisting of the High Resolution Fly's Eye (HiRes) prototype and the MIA muon array. Measurements have been made of the change in the depth of shower maximum, $X_{max}$, and in the change in the muon density at a fixed core location, $\rho_\mu(600m)$, as a function of energy. The composition has also been evaluated in terms of the combination of $X_{max}$ and $\rho_\mu(600m)$. The results show that the composition is changing from a heavy to lighter mix as the energy increases., Comment: 14 pages including 3 figures in revtex epsf style, submited to PRL

Abstract

It is an experimental evidence that all baryons are created polarized from unpolarized p—nucleus collisions. So far, the origin of this polarization remains unexplained in spite of the experimental evidences accumulated in the past thirty years. Up to these days, Λ0 is the most studied baryon for polarization, for it is copiously produced in p—nucleus collisions at the energies of the principal high energy physics accelerators of the world. This paper is an overview of the experimental evidences accumulated on the polarization of Λ0 from unpolarized exclusive pp collisions as function of xF, PT, and M(Λ0K+) in the past fifteen years inside Fermilab e690 experiment, in the particular reactions pp→pΛ0K0π+, pp→ppΛ0Λ-0, pp→pΛ0K+, produced at 800 GeV.

Abstract

We present preliminary results of the analysis of the centrally produced φφ system at 800 GeV/c in the reaction pp → Pslow (φφ)Pfast. A partial wave analysis of the data up to 2.6 GeV/c² shows that three waves with JPC LS = 2++02 and with different Jz and reflectivity are needed to describe the data. A fit to the wave amplitudes using Jost functions gives two resonances, one above and one below the φφ threshold. The resonance above threshold has a Breit­Wigner structure with MR = 2.243 ± 0.015(stat) ± 0.010(syst) GeV and ΓR = 0.368 ± 0.033(stat) ± 0.030(syst) GeV. [ABSTRACT FROM AUTHOR]

Abstract

We present some preliminary measurements of Λ[sup 0] polarization, in the final state pp → p{Λ[sup 0]K[sup +]) created at 800 GeV/c, as a function of P[sub T], x[sub F], and the diffractive mass of the object {Λ[sup 0]K[sup +]}. [ABSTRACT FROM AUTHOR]
