Anti-dark matter: a hidden face of mirror world

Understand

B and L violating interactions of ordinary particles with their twin particles from hypothetical mirror world can co-generate baryon asymmetries in both worlds in comparable amounts, $\Omega'_B/\Omega_B \sim 5$ or so.

• On the other hand, the same interactions induce the oscillation phenomena between the neutral particles of two sectors which convert e.g.
• mirror neutrons into our antineutrons.
• These oscillations are environment dependent and can have fascinating physical consequences.
