a 'freeze-in' event produced dark matter

Mysterious Dark Matter May Predate Big Bang
Dark matter, which makes up 80 percent of all matter in the universe, may have formed in the very short time before the big bang.
Could dark matter have been forged in a 'Dark Big Bang?'
“The assumption that dark matter and regular matter originated in the same event, the Big Bang, is natural, given its simplicity. That is why it remained unchallenged for so long," Ilie said. "However, nature does not need to be parsimonious, abide by Occam’s razor, or by any of our aesthetic preferences."
Just before the Big Bang, a ‘freeze-in’ event produced dark matter
Researchers have proposed a new model that suggests dark matter originated during the infinitesimally short span before the Big Bang.
Dark matter formation may have occurred before the Big Bang
A team of researchers has proposed an innovative model suggesting that dark matter might have originated before the Big Bang.
Observing dark matter at cosmic dawn
After almost a century of speculation, proposals and searches for dark matter, physicists now know that it currently comprises about 27% of the universe's mass-energy, with an abundance over five times that of ordinary matter like you,
Mysterious 'Dark Big Bang' Could Explain The Origins of Dark Matter
According to Freese and Winkler, however, a Dark Big Bang is consistent with the evidence for dark matter – as long as it happened promptly, within about a month of the first Big Bang.
Dark matter may have originated before Big Bang, says study
A team of researchers from the University of Texas at Austin (UT Austin) in the US has proposed a new model, indicating that dark matter may have originated in the short time before the Big Bang. The theory builds on physicist Alan Guth's 1981 idea of cosmic inflation,
Cosmological model proposes dark matter production during pre-Big Bang inflation
As physicists continue their struggle to find and explain the origin of dark matter, the approximately 80% of the matter in the universe that we can't see and so far haven't been able to detect, researchers have now proposed a model where it is produced before the Big Bang.
