摘要：

Inspired by the recent discovery of the pentaquark states P-c(4450) and P-c(4380), which can be viewed as excited nucleon states with hidden charm, we study the three-body interaction of a kaon and a pair of D (D) over bar* in isospin 0 and 1. We show that the two body interactions stringently constrained by the existence of the D-s0*(2317), D-s1*(2460), X(3872), and Z(c)(3900), which are widely believed to contain large DK, D*K, and D (D) over bar* components, inevitably lead to the existence of a heavy K* meson with hidden charm. Concrete coupled channel three-body calculations yield its mass and width as (4307 +/- 2) - i(9 +/- 2) MeV with I(J(P)) = 1/2(1(-)). This state, if found experimentally, definitely cannot be accommodated in a q (q) over bar picture, and therefore presents a clear case of an exotic hadron. (c) 2018 The Author(s).
