We present new $\ensuremath{\Sigma}$ beam asymmetry data for $\ensuremath{\eta}$ meson photoproduction on the proton, using a novel tagged, laser backscattered, linearly polarized photon up to 1.1 GeV. The show large, positive asymmetries, at all incident energies. In addition ${S}_{11}(1535)$ and ${D}_{13}(1520)$ resonances necessary reproduce cross sections, ${P}_{13}(1720)$ ${D}_{15}(1675)$ ``four stars'' contribute observable, but cannot strong forward asymmetries measured energies...
The total photoabsorption cross section for $^{7}\mathrm{Li}$, C, Al, Cu, Sn, Pb has been measured in the energy range 300--1200 MeV at Frascati with jet-target tagged photon beam. A 4\ensuremath{\pi} NaI crystal detector and a lead-glass shower counter were used, respectively, to measure hadronic events reject electromagnetic background. Data above 600 clearly indicate broadening of higher nucleon resonance peaks nuclei reduction absolute value per respect free-nucleon case. This large...
The cross section for the reaction ep-->e(')ppi(+)pi(-) was measured in resonance region 1.4<W<2.1 GeV and 0.5<Q2<1.5 GeV(2)/c(2) using CLAS detector at Jefferson Laboratory. data show resonant structures not visible previous experiments. comparison of our to a phenomenological prediction available information on N(*) Delta states shows an evident discrepancy. A better description is obtained either by sizable change properties P13(1720) or introducing new baryon state, reported published analyses.

Each module houses 31 3-in. photomultiplier tubes, instrumentation calibration signal and positioning module, all associated electronics boards. By design, total electrical power...
We report an absolute measurement of the tensor analyzing powers T20 and T22 in elastic electron-deuteron scattering at a momentum transfer 1.6fm−1. The novel approach this is use polarized 2H target internal to electron storage ring, with situ polarization gas. Scattered electrons recoil deuterons were detected coincidence two large acceptance nonmagnetic detectors. techniques demonstrated have broad applicability further measurements spin-dependent scattering.Received 10 May...

Of particular interest possibility direct beam from towards KM3NeT/ORCA detector, which currently under construction Mediterranean Sea 40 km offshore Toulon, France. This proposal known as P2O. Thanks its baseline 2595 km, this experiment would yield an unparalleled sensitivity matter effects Earth, allowing for...
The differential cross section for the reaction p(γ,ηp) has been measured from threshold to 1100 MeV photon laboratory energy. For first time, region of S11(1535) resonance is fully covered in a photoproduction experiment and will allow precise extraction its parameters at point. These high precision data together with already beam asymmetry provide stringent constraints on new couplings baryon resonances η meson.
We measured the inclusive electron-proton cross section in nucleon resonance region $(W<2.5\mathrm{GeV})$ at momentum transfers ${Q}^{2}$ below $4.5(\mathrm{GeV}{/c)}^{2}$ with CLAS detector. The large acceptance of allowed measurement a large, contiguous two-dimensional range and x, making it possible to perform an integration data fixed over significant x interval. From these we extracted structure function ${F}_{2}$ and, by including other world data, studied evolution its moments,...
