Query: Leptogenesis and Low Energy CP Violation   We discuss the possibility of relating the size and sign of the observed
baryon asymmetry of the universe to CP violation observable at low energies, in
a framework where the observed baryon asymmetry is produced by leptogenesis
through out of equilibrium decay of heavy Majorana neutrinos. We have shown
that although in general such a connection cannot be established, there are
specific frameworks where a link does exist. Furthermore, we identify the CP
violating phases relevant to leptogenesis and those relevant for low energy CP
violation and build weak basis invariant conditions for CP conservation.
