Query: Identifying Glueball at 3.02 GeV in Baryonic $B$ Decays   We examine the nature of the unknown enhancement around 3 GeV observed by the
BABAR collaboration in the $m_{p\bar p}$ spectrum of the $\bar B^0\to p\bar p
D^0$ decay. Suspecting that the peak is a resonance, which can be neither
identified as a charmonium state, such as $\eta_c$ or $J/\psi$, nor classified
as one of the light-flavor mesons, we conclude that it corresponds to a
glueball fitted as X(3020) with $(m_X,\;\Gamma_X)=(3020\pm 8,\; 107\pm
30)\;\text{MeV}$, which could be the first glueball state above 3 GeV. This
state also appears in the $m_{p\bar p}$ spectrum of the $\bar B^0\to p\bar p
D^{*0}$ decay.
