Abstract

he WIMP paradigm has been a guide towards the properties of DM for
many years. Its abundance today is determined due to its interactions
with the Standard Model, and since it is a thermal dark matter
candidate, its abundance is insensitive to initial conditions. It has
long been thought that a dark matter candidate with these properties
has its mass bounded above by around 100 TeV, according to the
so-called unitary bound. I will show that a thermal dark matter
candidate, much like the WIMP, can have mass well beyond this, all the
way up to the Planck scale. I will present three different freezeout
mechanisms--zombies, a chain, and squeeze out--that all predict dark
matter particles well above 100 TeV.

The seminar will be on Zoom, a link will be sent by email.
