Dark Matter

The Standard Model lacks a good explanation for the existence of dark matter. Over the past several decades it has become clear that something is not right with the dynamics of bodies on astronomical scales. The leading explanation for the observed discrepancies is the existence of a non-luminous form of matter, that is dark matter. The nature of the dark matter is a major unresolved problem in physics, and at the moment it cannot be accommodated within the Standard Model. One possibility, and one that I am particularly interested in, is that it is a new stable particle. There are major efforts around the world to search for dark matter directly in the lab as well as through indirect astrophysical observations. The different experimental frontiers form a fertile ground for progress:

  • Direct Detection of Dark Matter.
  • Indirect Detection of Dark Matter.
  • Models of Dark Matter.
  • Dark Matter in high energy colliders.
My own interests have recently been mostly in the following directions:
  • Theories of dark matter – extensions of the standard model of particle physics (e.g.1206.29101007.42000901.0283).
  • Understanding current data coming from the different experiments looking for dark matter, in the lab, in telescopes, and in colliders (e.g. 1004.06971111.4222).
  • Developing new ideas for searching for dark matter (since we have no idea what it is, the field is wide open). (e.g. 0910.1839 and 1111.4222)
