Analysis of the quantum numbers of the X(3872)

On this web page we present the constraints on the quantum numbers spin, parity and charge parity of the X(3872) state derived from the measurement of angular distributions.
The results were blessed in the B Physics Meeting on March 16, 2006 and are published in:


Our measurement shows that only the hypotheses

JPC = 1++ and 2-+

are compatible with data. All other considered JPC assupmtions are ruled out by more than three standard deviations (99.7% CL).
The analysis is summarized in more detail in CDF note 8201.
