Abstract
It is proposed that X(3872) is a vector glueball mixed with neighboring vector states of charmonium.
Highlights
The Belle Collaboration [1] recently reported the observation of a narrow state, dubbed X(3872) in the decay of a large sample of 152 million B mesons, B± → K±X, with X decaying into π+π−J/ψ
Several attempts have been made to search for X(3872) decays in final states other than π+π−J/ψ [1,5,6,7,8]. While all such searches are handicapped by poor statistics, the overall conclusion is that no positive signals have been observed in any, except perhaps in the decay X→ ωJ/ψ [7]
We propose an alternative to the current explanations of X(3872)
Summary
The Belle Collaboration [1] recently reported the observation of a narrow state, dubbed X(3872) in the decay of a large sample of 152 million B mesons, B± → K±X, with X decaying into π+π−J/ψ. In all four measurements ψ′(2S) decaying into π+π−J/ψ is observed rather strongly, with the corresponding X(3872) being a small fraction. Several attempts have been made to search for X(3872) decays in final states other than π+π−J/ψ [1,5,6,7,8].
