Observation of a new charged charmoniumlike state in B(overbar)0 -> J/? K-?+ decays
Original language description
We present the results of an amplitude analysis of B- 0 RIGHTWARDS ARROW J=?KMINUS SIGN ?? decays. A new charged charmoniumlike state Zc?4200?? decaying to J=??? is observed with a significance of 6.2?. The mass and width of the Zc?4200?? are 4196?31?17MINUS SIGN 29MINUS SIGN 13 MeV=c2 and 370?70?70 MINUS SIGN 70MINUS SIGN 132 MeV, respectively; the preferred assignment of the quantum numbers is JP 1/4 1?. In addition, we find evidence for Zc?4430?? RIGHTWARDS ARROW J=???. The analysis is based on a 711 fbMINUS SIGN 1 data sample collected by the Belle detector at the asymmetricenergy e?eMINUS SIGN collider KEKB.
