Abstract
The prospects for detecting a candidate supersymmetric dark matter particle at the LHC are reviewed, and compared with the prospects for direct and indirect searches for astrophysical dark matter. The discussion is based on a frequentist analysis of the preferred regions of the Minimal supersymmetric extension of the Standard Model with universal soft supersymmetry breaking (the CMSSM). LHC searches may have good chances to observe supersymmetry in the near future - and so may direct searches for astrophysical dark matter particles, whereas indirect searches may require greater sensitivity, at least within the CMSSM.
Highlights
(1) What is the origin of particle masses and, in particular, are they due to a Higgs boson? (2) Why are there so many different flavours of standard matter particles, e.g., three neutrino species? (3) What is the dark matter in the Universe? (4) How can we unify the fundamental forces? (5) Last but certainly not least, how may we construct a quantum theory of gravity? Each of these questions will be addressed, in some way, by experiments at the LHC, though answers to all of them are not guaranteed! I
These include searches at the LHC as well as astrophysical dark matter searches, and the presentation is based on my personal research in these areas: I apologize to others for not mentioning adequately their work, which is referred to in the papers referenced here
Phenomenological interest in looking for supersymmetry was sparked by the realization that it could stabilize the electroweak scale if supersymmetric partners or Standard Model particles weigh ∼ 1 TeV, and the flames of enthusiasm were fanned by the subsequent realizations that in this case it could facilitate unification of the fundamental interactions, would predict a light Higgs boson, and could explain the apparent discrepancy between the experimental value of gμ − 2 and theoretical calculations within the Standard Model [1]
Summary
The standard list of open questions beyond the Standard Model of particle physics [1] includes the following. (1) What is the origin of particle masses and, in particular, are they due to a Higgs boson? (2) Why are there so many different flavours of standard matter particles, e.g., three neutrino species? (3) What is the dark matter in the Universe? (4) How can we unify the fundamental forces? (5) Last but certainly not least, how may we construct a quantum theory of gravity? Each of these questions will be addressed, in some way, by experiments at the LHC, though answers to all of them are not guaranteed! I. (2) Why are there so many different flavours of standard matter particles, e.g., three neutrino species? As you can guess from the title of this talk is, its focus is on question (3) concerning dark matter and, in light of the above comments, on ways to probe experimentally supersymmetric models of dark matter. These include searches at the LHC as well as astrophysical dark matter searches, and the presentation is based on my personal research in these areas: I apologize to others for not mentioning adequately their work, which is referred to in the papers referenced here
