title = "Nucleosynthesis in a massive star associated with magnetohydrodynamical jets from collapsars",
abstract = "We investigate the nucleosynthesis during the stellar evolution and the jet-like supernova explosion of a massive star of 70 M⊙ having the solar metallicity in the main sequence stage. The nucleosynthesis calculations have been performed with large nuclear reaction networks, where the weak s-, p-, and r-processes are taken into account. As a result s-elements of 60 > A > 90 and r-elements of 90 > A > 160 are highly overproduced relative to the solar system abundances. We find that the Sr-Y-Zr isotopes are primarily synthesized in the explosive nucleosynthesis which could be one of the sites of the lighter element primary process (LEPP).",
