B-meson mixing

B-meson mixing is a quantum process where a B-meson, a particle containing a bottom quark, spontaneously transforms into its antiparticle, an anti-B-meson, and vice versa. This occurs because B-mesons and anti-B-mesons are quantum states that can fluctuate into each other due to the weak nuclear force, allowing them to "mix." This phenomenon provides insights into the fundamental asymmetries between matter and antimatter and helps test the predictions of the Standard Model of particle physics. The oscillation happens very rapidly, and studying it helps scientists understand the underlying rules of the universe.
