(3872) revisited; The Roles of OPEP and the quark degrees of freedomTakeuchi, Sachiko*; Yamaguchi, Yasuhiro 
; Hosaka, Atsushi; Takizawa, Makoto*
The (3872) is investigated by employing the quark-hadron hybrid model, that consists of the 
core, 
(*)
*, 
/
, and /
two-meson states. Due to the attraction from the -* coupling and from the OPEP tensor coupling, a very thin peak can appear at the 
threshold. The energy of the corresponding pole of the scattering matrix is 
= +0.06 - 0.14
MeV, which is on the physical sheet and above the threshold, the same as the one of the poles from the LHCb data analysis.
