The Decade of the WIMP

The bulk of the matter in the present universe is dark. The most attractive possibility for the nature of the dark matter is a new species of elementary particle known as a WIMP (a Weakly Interacting Massive Particle). After a discussion of how a WIMP might fit into models of particle physics, I will review the current situation with respect to direct detection, indirect detection, and collider production of WIMPs. Rapid advances in the field should enable us to answer by the end of the decade whether our universe is dominated by WIMPs.

The shape of atomic nuclei often deviates from a spherical mass distribution as soon as we leave arrangements with closed proton and neutron shells. The most common deviation from sphericity is the quadrupole deformation, i.e. elongated or compressed elipsoidal shapes, but higher order deviations exist as well. The development of nuclear deformation is intimately linked to the erosion of the (spherical) shell structure characterised by the so-called "magic numbers” of the nuclear shell model.

In a few millenia of recorded history, mankind has made great strides in its understanding of the Universe. We now know that the Big Bang created almost all visible matter as just two elements, hydrogen and helium, which were later turned into carbon, oxygen, iron and the 90+ other chemical elements by nucleosynthesis in stars. Many of these stars are gravitationally bound as close binary systems which may evolve quite differently to single stars leading to exotic phenomena such as thermonuclear novae and gamma-ray bursts.

Recent progress (or lack thereof) in direct searches for dark matter

We will review the landscape of this active field of research, covering both recent hints of possible detection, and negative results. I'll try to communicate the many difficulties we presently encounter when attempting to pinpoint a common origin for the several observed anomalies, or assessing their tension with existing exclusion limits.

Astrophysics' Extreme Matter Experiments: Understanding the Diagnostics

Astrophysical Transients (supernovae, gamma-ray bursts, kilanovae, ...) are often hailed as ideal laboratories to study matter at high temperatures and nuclear densities. But, as with any experiment, what we can learn about the physics of extreme matter depends both on the quality of the experiment: how well we can constrain the initial conditions and how well we can tie the observed diagnostics back to the physics we wish to study.
