High Resolution Spectroscopy of 12B_Lambda by Electroproduction

An experiment measuring electroproduction of hypernuclei has been performed in Hall A at Jefferson Lab on a $^{12}$C target. In order to increase counting rates and provide unambiguous kaon identification two superconducting septum magnets and a Ring Imaging CHerenkov detector (RICH) were added to the Hall A standard equipment. An unprecedented energy resolution of less than 700 keV FWHM has been achieved. Thus, the observed \lam{12}{B} spectrum shows for the first time identifiable strength in the core-excited region between the ground-state {\it s}-wave $\Lambda$ peak and the 11 MeV {\it p}-wave $\Lambda$ peak.Comment: Paper submitted to Physical Review Letter

Putting Food on the Regional Policy Agenda in Montpellier, France

International audienceWhile the food supply question virtually disappeared from the agenda of the cities of the developed world after World War II, a growing number of cities in the developing and developed world alike are now giving it their attention (Chapter “ Cities’ Strategies for Sustainable Food and the Levers They Mobilize”). That renewed focus has been brought about by a food supply discourse that seeks to promote a sustainable urban policy (Pothukuchi and Kaufman 2000). In that context, food supply has come to be at the heart of a new category of public urban action—sustainable development—that has now been widely undertaken in local public action (Béal et al. 2011)
