Rotating massive stars with initial progenitor masses $M_{rm prog} sim$ 25
$M_{odot}$ — $sim$140 $M_{odot}$ can leave rapidly rotating black holes to
become collapsars. The black holes and the surrounding accretion disks may
develop powerful jets by magneto-hydrodynamics instabilities. The propagation
of the jet in the stellar envelope provides the necessary shock heating for
triggering nucleosynthesis unseen in canonical core-collapse supernovae. Yet,
the energy budget of the jet and its effects on the final chemical abundance
pattern are unclear. In this exploratory work, we present a survey on the
parameter dependence of collapsar nucleosynthesis on jet energetics. We use the
zero-metallicity star with $M_{rm prog} sim$ 40 $M_{odot}$ as the
progenitor. The parameters include the jet duration, its energy deposition
rate, deposited energy, and the opening angle. We examine the correlations of
following observables: (1) the ejecta and remnant masses, (2) the energy
deposition efficiency, (3) the $^{56}$Ni production and its correlation with
the ejecta velocity, deposited energy, and the ejected mass, (4) the Sc-Ti-V
correlation as observed in metal-poor stars, and (5) the [Zn/Fe] ratio as
observed in some metal-poor stars. We also provide the chemical abundance table
of these explosion models for the use of the galactic chemical evolution and
stellar archaeology.
