We present deeply virtual π^{0} electroproduction cross-section measurements at x_{B}=0.36 and three different Q^{2} values ranging from 1.5 to 2  GeV^{2}, obtained from Jefferson Lab Hall A experiment E07-007. The Rosenbluth technique is used to separate the longitudinal and transverse responses. Results demonstrate that the cross section is dominated by(More)
4 Fonds pour la Formation a la Recherche dans l'Industrie et dans l'Agriculture. ABSTRACT A new experimental apparatus, designed principally for a high sensitivity search for ! oscillation, has been successfully constructed and made operational by the CHORUS Collaboration for the CERN-WA95 experiment. It consists of a large emulsion target, a scintillating(More)
The parity-violating cross-section asymmetry in the elastic scattering of polarized electrons from unpolarized protons has been measured at a four-momentum transfer squared Q2 = 0.624  GeV2 and beam energy E(b) = 3.48  GeV to be A(PV) = -23.80 ± 0.78(stat) ± 0.36(syst) parts per million. This result is consistent with zero contribution of strange quarks to(More)
We propose to measure the parity-violating electroweak asymmetry A P V in the deep-inelastic scattering of polarized electrons (PVDIS) to high precision in order to search for physics beyond the Standard Model in lepton-quark neutral current interactions. As described in the original document (proposal E09-012), the proposed measurement is unique in that it(More)
We report the first longitudinal-transverse separation of the deeply virtual exclusive π^{0} electroproduction cross section off the neutron and coherent deuteron. The corresponding four structure functions dσ_{L}/dt, dσ_{T}/dt, dσ_{LT}/dt, and dσ_{TT}/dt are extracted as a function of the momentum transfer to the recoil system at Q^{2}=1.75  GeV^{2} and(More)
A review of the latest results from the WA97 experiment on the strange particle production in Pb–Pb and p–Pb collisions is presented. Transverse mass spectra and yields of K 0 S , Λ, Ξ, Ω and h − (negatively charged particles) have been measured at central rapidity. Yields are studied as a function of the number of nucleons participating in the collision(More)
MeV-GeV dark matter (DM) is theoretically well motivated but remarkably unexplored. This Letter of Intent presents the MeV-GeV DM discovery potential for a 1 m 3 segmented plastic scintillator detector placed downstream of the beam-dump at one of the high intensity JLab experimental Halls, receiving up to 10 22 electrons-on-target (EOT) in a one-year(More)
Understanding quark and gluon confinement in Quantum Chromodynamics is one of the outstanding issues in physics. To this end, meson spectroscopy is a powerful tool to investigate how the QCD partons manifest themselves under the strong interaction at the energy scale of the nucleon mass (GeV). We propose a comprehensive study of the meson spectrum with(More)
