Ke hoʻomau nei ka pīhoihoi o nā hadrons exotic, a i ʻole physics
Ua hōʻoia ka poʻe ʻepekema CERN i nā hoʻokolohua ma ka Large Hadron Collider, i kapa hou ʻia ʻo Large Hadron Beauty Collider (LHCb), ua ʻike i nā mea hou i kapa ʻia ʻo "exotic hadrons". ʻAʻole hiki ke unuhi ʻia ko lākou inoa mai ke ʻano quark kuʻuna.
He mau ʻāpana ʻo Hadrons i nā pilina ikaika, e like me nā kuleana o nā paʻa i loko o kahi nucleus atom. Wahi a nā kumumanaʻo e pili ana i ka makahiki 60, aia nā quarks a me nā antiquarks - mesons, a i ʻole ʻekolu quarks - baryons. Eia naʻe, ʻaʻole i kūpono ka ʻāpana i loaʻa ma LHCb, i kaha ʻia ʻo Z (4430), i ka manaʻo quark, no ka mea, ʻehā mau quark.
Ua ʻike ʻia nā ʻāpana mua o ka ʻāpana exotic i ka makahiki 2008. Eia naʻe, ʻaʻole i hiki i kēia manawa ke hōʻoia ʻo Z(4430) kahi ʻāpana me ka nuipaʻa o 4430 MeV/c2, he ʻehā paha ia o ka nui o ka proton (938 MeV/c2). ʻAʻole i manaʻo nā physicists i ke ʻano o ke ʻano o nā hadrons exotic.
