Mysterious baryon resonance is a subatomic molecule, say physicists

(Phys.org)A team of researchers with the University of Adelaide and the Australian National University has found that the excited state of the Lambda baryon, ?(1405), is actually a type of quark molecule. In their paper published in the journal Physical Review Letters, the researchers describe how they ran simulations on a computer that confirmed the properties of the unique particles.
