Now, a preprint posted online on 14 November reopens the question of what the wavefunction represents — with an answer that could rock quantum theory to its core.

The two most familiar baryons, protons and neutrons, are made up of the lightest quarks, the up and down (either two up and one down or vice versa, respectively). But it's also possible to construct similar baryons with the heavier, unstable quarks; many of these have been observed, and some of them have been incorporated into atomic nuclei within the brief time that they survive.
