Abstract
We examine the nature of the unknown enhancement around 3 GeV observed by the BaBar Collaboration in the mpp¯ spectrum of the B¯0âpp¯D0 decay. Suspecting that the peak is a resonance, which can be neither identified as a charmonium state, such as ηc or J/Ï, nor classified as one of the light-flavor mesons, we conclude that it corresponds to a glueball fitted as X(3020) with (mX,ÎX)=(3020±8,107±30)MeV, which could be the first glueball state above 3 GeV. This state also appears in the mpp¯ spectrum of the B¯0âpp¯Dâ0 decay.
