Hadron Physics at J-PARC

Abstract

The Japan Proton Accelerator Research Complex, J‐PARC, has just finished its phase‐1 construction, and the proton beams have been delivered to the experimental facilities. The hadron experimental hall (Hadron Hall) is one of the experimental facilities at J‐PARC, where secondary beams such as pions and kaons, as well as the primary proton beams, will be used for fixed target experiments. The first proton beam to the Hadron Hall was delivered in January and February, 2009, and the beam was resumed from October. The first experiments at the Hadron Hall are just being started, at a low‐momentum beam lines for chaged partticle beams (K1.8BR and K1.8) and at a neutral kaon beam line. Other beam lines, such as K1.1 and high momentum beam lines, are planned. In this talk, physics topics to be conduced at the Hadron Hall will be introduced as well as the status and plan of the facility.
