Title: Upper limits for the photoproduction cross section for the Φ⁻⁻(1860) pentaquark state off the deuteron

Abstract

We searched for the Φ⁻⁻(1860) pentaquark in the photoproduction process off the deuteron in the Ξ⁻π⁻-decay channel using CLAS. The invariant-mass spectrum of the Ξ⁻π⁻ system does not indicate any statistically significant enhancement near the reported mass M=1.860 GeV. The statistical analysis of the sideband-subtracted mass spectrum yields a 90%-confidence-level upper limit of 0.7 nb for the photoproduction cross section of Φ⁻⁻(1860) with a consecutive decay intoΞ⁻π⁻ in the photon-energy range 4.5GeV_γ<5.5GeV.

Upper limits for the photoproduction cross section for the Phi--(1860) pentaquark state off the deuteron

Journal Article Egiyan, Hovanes - Physical Review, C (Nuclear Physics)

We searched for the {Phi}{sup --}(1860) pentaquark in the photoproduction process off the deuteron in the {Xi}{sup -} {pi}{sup -} decay channel using CLAS. The invariant mass spectrum of the {Xi}{sup -} {pi}{sup -} system does not indicate any statistically significant enhancement near the reported mass M = 1.860 GeV. The statistical analysis of the sideband-subtracted mass spectrum yields a 90% confidence level upper limit of 0.7 nb for the photoproduction cross section of {Phi}{sup --}(1860) with a consecutive decay into {Xi}{sup -} {pi}{sup -} in the photon energy range 4.5 GeV < E{sub {gamma}} < 5.5 GeV.

Studies of $$\Lambda n$$ interaction through polarization observables for final-state interactions in exclusive $$\Lambda$$ photoproduction off the deuteron

Conference Ilieva, Yordanka ; Cao, Tongtong ; Zachariou, Nicholas - Proceedings of Science

Theoretical studies suggest that experimental observables for hyperon production reactions can place stringent constraints on the free parameters of hyperon-nucleon potentials, which are critical for the understanding of hypernuclear matter and neutron stars. Here we present preliminary experimental results for the polarization observables S, Py, Ox, Oz, Cx, and Cz for final-state interactions (FSI) in exclusive L photoproduction off the deuteron. The observables were obtained from data collected during the E06-103 (g13) experiment with the CEBAF Large Acceptance Spectrometer (CLAS) in Hall B at Jefferson Lab. The g13 experiment ran with unpolarized deuteron target and circularly- and linearly-polarized photon beamsmore »« less

Search for Phi(1862) Pentaquark States with CLAS

Conference Egiyan, Hovanes

Following the first observations of the possible S = +1 pentaquark state Phi+(1540), there have been many experiments in various laboratories to confirm these results and to search for states which could be associated with other members of the pentaquark antidecuplet. The NA49 collaboration reported the observation of narrow S = ?2 states with masses about 1860 GeV showing in the Xi-pi invariant mass spectra. These states were identified as isospin 3/2 members of the pentaquark antidecuplet, and were named Phi(1862). However, other experiments have failed to reproduce these results. A new experiment has recently been performed at Jefferson Labmore »« less
Measurement of polarization observables in vector meson photoproduction using a transversely-polarized frozen-spin target and polarized photons at CLAS, Jefferson Lab

Thesis/Dissertation Roy, Priyashree

The study of baryon resonances provides a deeper understanding of the strong interaction because the dynamics and relevant degrees of freedom hidden within them are re ected by the properties of the excited states of baryons. Higher-lying excited states at and above 1.7 GeV/c² are generally predicted to have strong couplings to final states involving a heavier meson, e. g. one of the vector mesons, ρ, ω φ, as compared to a lighter pseudoscalar meson, e. g. π and η. Decays to the ππΝ final states via πΔ also become more important through the population of intermediate resonances. We observe that nature invests in mass rather than momentum. The excited states of the nucleon are usually found as broadly overlapping resonances which may decay into a multitude of final states involving mesons and baryons. Polarization observables make it possible to isolate single resonance contributions from other interference terms. The CLAS g9 (FROST) experiment, as part of the N* spectroscopy program at Jefferson Laboratory, accumulated photoproduction data using circularly- & linearly-polarized photons incident on a transversely-polarized butanol target (g9b experiment) in the photon energy range 0:3-2:4 GeV & 0:7-2:1 GeV, respectively. In this work, the analysis of reactions and polarization observables which involve two charged pions, either in the fully exclusive reaction γρ -> ρπ+π- or in the semi-exclusive reaction with a missing neutral pion, γρ -> ρπ⁺π^-(π⁰) will be presented. For the reaction ρπ⁺π^-, eight polarization observables (I^s, I^c, P_x, P_y,more »« less

Searches for the pentaquark states {xi}(1860){sup 0} and {xi}(1860){sup --} in neutron-carbon interactions via the EXCHARM experiment

Journal Article Aleev, A N ; Amaglobeli, N S ; Balandin, V P ; ... - Physics of Atomic Nuclei

Results of searches for the pentaquark states {xi}(1860){sup 0} and {xi}(1860){sup --} in neutron-carbon interactions at an average neutron energy of about 51 GeV via the EXCHARM experiment are presented. No such states are found in the {xi}{sup -}{pi}{sup +} and {xi}{sup -}{pi}{sup -} effective-mass spectra examined in this study. Upper limits on the cross sections for {xi}(1860){sup 0} and {xi}(1860){sup --} production are estimated.
