Structure of the X(3872) and its Isospin Symmetry Breaking
In order to understand the structure of the X(3872), we have studied the effects of the ${c}ar{c}$ charmonium core state coupling to the D0 $ar{D^{0}*}$ and D+ D−* molecule states. We determine the coupling strength so as to reproduce the observed mass of the the X(3872). The isospin symmetry break...

| Summary: | In order to understand the structure of the X(3872), we have studied the effects of the ${c}ar{c}$ charmonium core state coupling to the D0 $ar{D^{0}*}$ and D+ D−* molecule states. We determine the coupling strength so as to reproduce the observed mass of the the X(3872). The isospin symmetry breaking is introduced by the mass differences of the neutral and charged $ar{D*}}$ mesons. The obtained structure of the X(3872) is about 15% of ${c}ar{c}$ charmoniumu, 72% of the isoscalar D$ar{D*}}$ molecule and 13% of the isovector D$ar{D*}}$ molecule which explains observed properties of the X(3872) well. |
