Another consequence of the decoupling was that the baryons lost their pressure support and began to collapse into gravitational potential wells.
Other, higher states of charmed baryons, which decay by the strong interaction, typically have large intrinsic widths.
Within astrophysics his research contributions have ranged from baryon asymmetry to pulsar kicks.
Protonium is an electrically neutral boson with zero baryon number.
Before that, it is thought that the expansion was decelerating, due to the attractive influence of dark matter and baryons.
These baryons are further composed of subatomic fundamental particles known as quarks bound by the strong interaction.
In the supersymmetry theory of particle physics, ordinary quarks and leptons have scalar partners that carry baryon and lepton numbers.
They are baryons containing no up or down quarks.
