Resumen

Conventional, hadronic matter consists of baryons and mesons made of three quarks and a quark–antiquark pair, respectively^1,2. Here, we report the observation of a hadronic state containing four quarks in the Large Hadron Collider beauty experiment. This so-called tetraquark contains two charm quarks, a u¯ and a d¯ quark. This exotic state has a mass of approximately 3,875 MeV and manifests as a narrow peak in the mass spectrum of D⁰D⁰π⁺ mesons just below the D^*+D⁰ mass threshold. The near-threshold mass together with the narrow width reveals the resonance nature of the state.
