The Newly Found Tetra Quark !
The particle: (duu) is a proton (ddu) is a neutron, the
TETRA QUARK (dduu : below) is THE NEW PARTICL, which is Just like the Neutron is the (dduu) Quark even more unstable as singular particle. (Q-FFF Theory)
Inside the aggressive oscillating vacuum sea, both particles are unstable caused by the chiral !! (supposed right handed in Q-FFF Theory) oscillating vacuum lattice structure. The (d) quark is unstable of dduu becoming a duu PROTON leaving electron behind to form Hydrogen first after the big bang.
