Status of J-PARC K1.8 Beam Line
Abstract
The commissioning of the K1.8 beam line in the hadron hall of J-PARC has been going very well. In November 2011, the first physics data was taken for E19 experiment, which is the day-one experiment in the hadron hall of J-PARC. A preliminary result of E19 exhibits no peak for pentaquark Θ+ around 1540 MeV.
