Title: Observation of an alternative χ c 0 ( 2 P ) candidate in e + e - J / ψ D D ¯

Abstract

We perform a full amplitude analysis of the process e + e - → J/ψ$$D\bar{D}$$, where D refers to either D 0 or D +. A new charmoniumlike state X*(3860) that decays to$$D\bar{D}$$ is observed with a significance of 6.5σ. Its mass is (3862 $$+26+40\atop{-32-13}$$) MeV=c 2, and its width is (201 $$+154+88\atop{-67-82}$$) MeV. The J PC 0 ++ hypothesis is favored over the 2 ++ hypothesis at the level of 2.5σ.
