>SQM consists of comparable amounts of up, down, and strange quarks. One of the new results of the latest study is that quark matter without strange quarks, i.e., udQM, has lower bulk energy per baryon than either SQM or hadronic matter, making it energetically favorable.
I would guess QM composed of strange quarks in addition to up and down, and/or below the "continent of stability" size of 300 Angstroms[1].
[1] Correction: A, not Angstroms
- time-of-flight 8y agoJust a clarification: A here doesn't mean Angstroms. It means "number of nucleons", as in carbon-12 is an A=12 system. So they're saying A>300 means "a quark system with >900 quarks"; normal protons and neutrons have three quarks a piece. If I misinterpreted your comment and the above was already clear to you, please forgive my mistake (I didn't want anyone to confuse A for angstroms here).
- WiseWeasel 8y agoAh, thank you for the clarification.
