Matter-antimatter annihilation and inflation

[stoomart]

Is there any link between the energy released from the annihilation of matter-antimatter during baryogenesis and cosmic inflation or expansion/dark energy?

This question came up when reading: https://www.nasa.gov/mission_pages/chandra/news/08-160.html

According to the Big Bang model, the Universe was awash in particles of both matter and antimatter shortly after the Big Bang. Most of this material annihilated, but because there was slightly more matter than antimatter -- less than one part per billion -- only matter was left behind, at least in the local Universe.

No. After inflation there was nothing but the inflaton field. The creation of a particle soup and consequently baryogenesis happens much later.

Dark energy is something that was completely irrelevant until quite recently.

Thanks for the info, it helped me track down this timeline description for the early universe:
