Deciphering the recently discovered tetraquark candidates around 6.9 GeV

Recently a novel hadronic state of mass 6.9 GeV, that decays mainly to pair charmonia, was observed in LHCb. The data also reveals broader structure centered around 6490 MeV and suggests another unconfirmed resonance at 7240 MeV, very near the threshold two doubly charmed $\Xi_{cc}$ baryons. We argue this note these exotic hadrons are genuine tetraquarks not molecules charmonia. It is conjectured they V-baryonium tetraquarks, namely, have an inner baryonic vertex with $cc$ diquark attached it, which connected by string anti-baryonic $\bar c \bar c$ anti-diquark. examine states as analogs $\Psi(4360)$ $Y(4630)$/$\Psi(4660)$ charmonium-like tetraquarks. One way test claims searching for significant decay 7.2 GeV into $\Xi_{cc}\overline\Xi_{cc}$. Such would be analog $Y(4630)$ $\Lambda_c\overline\Lambda_c$. further there should trajectories both orbital radial excited $X(6900)$. predict their masses. possible few already been seen
