Abstract
We study the $Za_1$ decay mode of a heavy CP-even Higgs boson of the NMSSM,
$h_2$, where $a_1$ is the lightest CP-odd Higgs state of this scenario, the
former produced in association with a bottom-antibottom pair, and find that,
despite small event rates, a significant (in fact essentially background free)
signal should be extractable at the LHC with very high luminosity, so long that
a $Z\to jj$ (where $j$ represents a jet) and $a_1\to \tau^+\tau^-$ final state
is exploited, in presence of $b$-tagging
