Title: X(3872) as the {sup 1}D{sub 2} charmonium

The {sup 1}D{sub 2} charmonium assignment for the X(3872) is considered, which is compatible with the 2{sup −+} quantum numbers, as favoured by the BABAR Collaboration analysis presented recently for the π{sup +}π{sup −}π{sup 0}J/ψ decay mode. It is demonstrated that established properties of the X(3872) are in a drastic conflict with the {sup 1}D{sub 2}c c-bar assignment. Furthermore, it is argued that a combined analysis of the data for different decay channels of the X, with the help of theoretical formulae which meet a number of constraints imposed by phenomenology, results in a suitable description of the experimental data for the X compatible with its quantum numbers 1{sup ++}.
