Detection Of Muons And K(L)(0) Mesons From E(+)E(-) Collisions Using The Endcap Rpc Module In The Belle Detector

The BELLE experiment[1] at KEKB has collected beam collision data from June Ist through August 4th, 1999, corresponding to an integrated luminosity of 25 pb(-1), and the data contain approximately 10,000 e(+)e(-) --> mu (+)mu (-) events and 50,000 hadronic events. Using those events, we study the performance of the endcap RPC modules in the BELLE detector. The study shows that the endcap RPC modules perform quite well in detecting muons and K(L)(0) mesons.
