Talk

While the axion is the most popular solution to the strong CP problem, it is sometimes claimed that the strong CP problem can be solved by imposing parity or CP as a symmetry of the theory or perhaps to ignore the strong CP problem completely by fine tuning the theta angle. For these solutions to work, the theta angle has to be a parameter of the theory. I will argue that this is incorrect -...

115. Dark Matter at Colliders

Jonathan Lee Feng (University of California Irvine (US))

Talk

The search for dark matter and dark sectors at colliders will be reviewed. Special attention will be paid to both heavy and light dark matter scenarios in which the dark matter is a thermal relic, but other possibilities that inspire interesting collider searches will also be included.

50. Dark Matter Production in Unusual Cosmologies

Talk

I will discuss how the assumption of a standard cosmological history can play a large role in the production of dark matter in the early Universe, and explore a few examples in which a nonstandard history can point to radically different parameters and/or models of dark matter to explain its observed abundance than one would have inferred from the standard assumptions about the conditions in...
