The dark matter puzzle is one of deepest and longest-standing problems in Science. While there is overwhelming evidence that dark matter is the building block of all structures in the Universe, its nature remains unknown.

There are several theoretical frameworks predicting that dark matter halos - including the halo of our own galaxy - are made of particles which can annihilate in pairs or decay into ordinary Standard Model states, giving rise to exotic astrophysical signals.

The focus in recent years has been in particular on the search for exotic components with gamma- and cosmic-ray observatories, with a dramatic improvement in quality and coverage of the available data. 

Unfortunately, for none of the originally proposed targets a dark matter signal stands clearly above backgrounds from standard astrophysical sources: it is then apparent that to keep exploiting these channels as efficient tools to either discover dark matter or set constraints on dark matter candidates, a closer addressing of signals and backgrounds are needed. 

We illustrate this point for two targets, the Galactic center and dwarfs satellites which most recently have been highlighted, respectively, as most promising for a tentative detection and most constraining on particle dark matter models.

Tobias Erhardt (Technische Universität, München) will give a seminar in the lunch area, 8th floor N.H. Abel's House at 14:15 November 24th.

Arnaud Brothier, Vanderbilt University (USA) will give a talk with title: Analytic properties for subfactors

Abstract:

I will discuss analytic properties for groups and their generalizations to subfactors, standard invariants, and certain tensor categories.

I will present a class of subfactor planar algebras that are constructed with a group acting on a bipartite graph.

I will show that if the group satisfies a given approximation property (such as amenability, Haagerup property, or weak amenability), then the subfactor planar algebra satisfies it as well.

I will exhibit an infinite family of subfactor planar algebras with non-integer index that are non-amenable, have the Haagerup property, and have the complete metric approximation property.

”Relationships between behavioural traits in wild great tits Parus major”

Björn Herrmann, LAPTh (Annecy)

A powerful tool to constrain a new physics model is to predict the relic density of dark matter and compare it to the recent limits published by Planck in order to identify (dis)favoured regions of parameter space. After reviewing the standard calculation of the dark matter relic density in the freeze-out picture, I will discuss several uncertainties entering this calculation. Focusing then on the particle physics aspects, I will consider the case of the Minimal Supersymmetric Standard Model and present the project DM@NLO, which aims at improving the preciction of the neutralino relic density by including radiative corrections to the (co)annihilation cross-section of the dark matter candidate. In particular, I will show that the impact of these corrections can be numerically larger than the current experimental uncertainty on cosmological data.
