We perform a theoretical study on the $$D\bar{D}K$$ D D ¯ K three body system, using the fixed center approximation to the Faddeev equations, considering the interaction between D and K, D and $$\bar{D}$$ D ¯ from the chiral unitary approach. We assume the scattering of K meson on a clusterized system $$D\bar{D}$$ D D ¯ , where a scalar meson X(3720) could be formed. Thanks to the strong DK interaction, where the scalar $$D^*_{s0}(2317)$$ D s 0 ∗ ( 2317 ) meson is dynamically generated, a resonance structure shows up in the modulus squared of the three body K-$$(D\bar{D})_{X(3720)}$$ ( D D ¯ ) X ( 3720 ) scattering amplitude and supports that a $$D\bar{D}K$$ D D ¯ K bound state can be formed. The result is in agreement with previous theoretical studies, which claim a new excited hidden charm K meson, $$K_{c\bar{c}}(4180)$$ K c c ¯ ( 4180 ) with quantum numbers $$I(J^P) = \frac{1}{2}(0^-)$$ I ( J P ) = 1 2 ( 0 - ) and mass about 4180 MeV. It is expected that these theoretical results motivate its search in experimental measurements.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
