Ξ Spectroscopy in Photoproduction on a Proton Target at Jefferson Lab ∗
نویسندگان
چکیده
The CLAS Collaboration at Jefferson Lab conducted a photoproduction experiment on a proton target using a tagged photon beam with an energy range of 1.5-3.8 GeV during May-July 2004. With an integrated luminosity of about 75 pb −1 , this experiment provides the largest data set for photon-proton reactions ever collected. The reaction γp → K + K + Ξ − (1320) has been investigated and the preliminary results of the cross section measurement of Ξ − (1320) for the photon energy range of 2.7-3.8 GeV have been obtained. In a search for excited cascade states, the reaction of γp → K + K + π − (Ξ 0 (1320)) has also been explored.

Photoproduction of the f1(1285)/η(1295) Mesons using CLAS at Jefferson Lab
This work presents the results of analysis of a meson of mass mx = 1281.0 ± 0.8 MeV/c and a FWHM of Γx = 18.4 ± 1.4 MeV/c seen in CLAS at Jefferson Lab in photoproduction off the proton, γp → xp. The f1(1285), η(1295) or both are candidates for this observed state. Neither of these states has previously been observed in photoproduction. The meson was measured in the decay modes x → ηπ+π−, K+K̄0π...
متن کاملNeutron Transversity at Jefferson Lab
Nucleon transversity and single transverse spin asymmetries have been the recent focus of large efforts by both theorists and experimentalists. On-going and planned experiments from HERMES, COMPASS and RHIC are mostly on the proton or the deuteron. Presented here is a planned measurement of the neutron transversity and single target spin asymmetries at Jefferson Lab in Hall A using a transverse...

متن کاملThe N * Physics Program at Jefferson Lab
Recent measurements of nucleon resonance transition form factors with CLAS at Jefferson Lab are discussed. The new data confirm the assertion of the symmetric constituent quark model of the Roper as the first radial excitation of the nucleon. The data on high Q nπ production better constrain the branching ratios βNπ and βNη for the S11(1535). For the first time, the longitudinal transition ampl...
متن کاملStudy of Generalized Parton Distributions with Clas at Jefferson Lab
In the past nearly five decades of electron scattering, experiments have focussed either on the measurements of form factors using exclusive processes or on measurements of inclusive processes to extract deep inelastic structure functions. Elastic processes measure the momentum transfer dependence of form factors, while the latter ones probe the quark’s longitudinal momentum and helicity distri...
