Other Theorized Quark Formations
- Jaffe 1977, suggested a four-quark state with strangeness (qsqs).
- Jaffe 1977 suggested the H dibaryon, a six-quark state with equal numbers of up-, down-, and strange quarks (represented as uuddss or udsuds).
- Bound multi-quark systems with heavy quarks (QQqq).
- In 1987, a pentaquark state was first proposed with a charm anti-quark (qqqsc).
- Pentaquark state with an antistrange quark and four light quarks consisting of up- and down-quarks only (qqqqs).
- Light pentaquarks are grouped within an antidecuplet, the lightest candidate, Ө+.
- This can also be described by the diquark model of Jaffe and Wilczek (QCD).
- Ө++ and antiparticle Ө−−.
- Doubly strange pentaquark (ssddu), member of the light pentaquark antidecuplet.
- Charmed pentaquark Өc(3100) (uuddc) state was detected by the H1 collaboration.
