Feasibilty to search for new charmonium(-like) reasonances in B± → χc1 π+π− K± decays at Belle. — •Elisabeth Panzenboeck1,2, Ariane Frey1, Kenkichi Miyabayashi2 und Vishal Bhardwaj2 — 1Georg August Universitaet, Goettingen — 2Nara Women’s University, Nara, Japan
The Belle experiment, located at KEK in Japan, has accumulated high statistics B meson data thanks to the highest luminosity in the world provided by the KEKB asymmetric-energy e+e− collider. The huge amount of data, corresponding to 772M B meson pairs, brings the opportunity to search for yet unestablished charmonium as well as exotic charmonium-like states. The outcome of this attempt will provide important information to determine the proper degree of freedom to describe these heavy-flavored hadrons.
In order to search for a new X(3872) decay mode or a still unseen χc1(2P), B± → χc1(1P) π+π− K± is a suitable decay process. Using Monte Carlo simulation datasets, the method of signal reconstruction and background estimation are to be presented.
