Title: Latest results from GRAAL collaboration
Keywords: meson photproduction, beam polarization asymmetry
Abstract:
Latest results on beam asymmetry measurements for pseudoscalar meson photoproduction on quasi-free neutron are presented. It is shown that important constraints on PWA of pion photoproduction ractions are provided by the new data set. Single and double polarization observables on K+ production from the proton are also extracted and are proved to be important to understand the role of "missing resonances" in the reaction mechanism. A short overview of some of the most important results from the GRAAL collaboration due to the intense and original work of Dr. Eid Hourany is presented to honor his memory.
