Near-threshold DD¯$$ \mathrm{D}\overline{\mathrm{D}} $$ spectroscopy and observation of a new charmonium state

Abstract Using proton-proton collision data, corresponding to an integrated luminosity of 9 fb−1, collected with the LHCb detector between 2011 and 2018, a new narrow charmonium state, the X(3842) resonance, is observed in the decay modes X3842→D0D¯0$$ \mathrm{X}(3842)\to {D}^0{\ove...
