X(3872) as a 1D2 charmonium state
Yu.S.Kalashnikova, A.V.Nefediev (ITEP, Moscow)
TL;DR
This paper critically examines the hypothesis that the X(3872) meson is a 1D2 charmonium state, finding significant conflicts with observed properties and questioning this assignment.
Contribution
It provides a detailed analysis that challenges the 1D2 charmonium interpretation of X(3872), based on recent experimental quantum number results.
Findings
Established properties of X(3872) conflict with 1D2 charmonium assignment
Recent BABAR results favor 2-+ quantum numbers for X(3872)
The 1D2 hypothesis is incompatible with observed data
Abstract
The 1D2 charmonium assignment for the X(3872) meson is considered, as prompted by a recent result from the BABAR Collaboration, favouring 2-+ quantum numbers for the X. It is shown that established properties of the X(3872) are in a drastic conflict with the 1D2 c-anti-c assignment.
