First Measurement of the Beam Asymmetry in Photoproduction off the Proton near Threshold
P. Levi Sandri, G. Mandaglio, V. De Leo +33
The beam asymmetry in photoproduction off the proton was measured at the GrAAL polarised photon beam with incoming photon energies of 1.461 and 1.480 GeV. For bo…
Eta photoproduction off the neutron at GRAAL
V. Kuznetsov, O. Bartalini, V. Bellini +24
The gamma n -> eta n quasi-free cross section reveals a resonant structure at W ~ 1.675 GeV. This structure may be a manifestation of a baryon resonance. A priori its properties, t…
Beam asymmetry measurements on the photoproduction off neutrons
G. Mandaglio, F. Mammoliti, M. Manganaro +30
The beam asymmetry in the photoproduction of negative pions from quasi-free neutrons in a deuterium target was measured at Graal in the energy interval 700 - 1500 MeV and a wi…
A new limit on the light speed isotropy from the GRAAL experiment at the ESRF
V. G. Gurzadyan, V. Bellini, M. Beretta +32
When the electrons stored in the ring of the European Synchrotron Radiation Facility (ESRF, Grenoble) scatter on a laser beam (Compton scattering in flight) the lower energy of the…
Eta photoproduction off the neutron at GRAAL: Evidence for a resonant structure at W=1.67 GeV
V. Kuznetsov, O. Bartalini, V. Bellini +24
New (preliminary) data on eta photoproduction off the neutron are presented. These data reveal a resonant structure at W=1.67 GeV.
Dark matter search in a Beam-Dump eXperiment (BDX) at Jefferson Lab: an update on PR12-16-001
M. Battaglieri, A. Bersani, G. Bracco +123
This document is an update to the proposal PR12-16-001 Dark matter search in a Beam-Dump eXperiment (BDX) at Jefferson Lab submitted to JLab-PAC44 in 2016 reporting progress in add…
