The High Energy, Cosmology and Astroparticle Physics (HECAP) section at ICTP is studying some of the most exciting areas in physics today, from string theory to physics at large energy colliders, from neutrino phenomenology to alternative cosmologies.
HECAP collaborates closely with the staff of the International School for Advanced Studies (SISSA), the Department of Theoretical Physics of Trieste University, and with the physicists of the Trieste section of the Italian National Institute of Nuclear Physics (INFN).

Milky Way Dark Matter and the Direct Detection Exclusion Limits
Abstract. For simplicity, experimental dark matter (DM) direct detection exclusion curves in the literature are almost always calculated by assuming a naive Standard Halo Model (SHM) expectation for the Milky Way (MW) DM halo. There have been a number of attempts that have tried to go beyond the SHM and assess the impact of astrophysical uncertainties on DM direct detection experiments. Most of these attempts have examined the impact of an uncertain local dark matter density which results in a trivial re-scaling of the exclusion curves. Others have attempted to look at the effect of the DM velocities via changes in the local DM escape speed and the local DM velocity dispersion, or have tried to incorporate the local DM velocity distribution but have mainly restricted to ansatzes or simulations.
We claim that the right approach should be to use an observationally inferred determination, along with the related uncertainties, of the local DM phase-space in a self- consistent manner. In this talk, I will present a detailed look at this fundamentally important element of DM detection results. We start by constructing the MW DM rotation curves and end with re-estimates of the direct detection DM exclusion limits. On the way, we present the tightest constraint on local DM density till date.

The HECAP section has research and visitors' programmes mostly aimed at scientists from developing countries.
The main motivation to study string theory is because it promises to provide a framework to unify all matter and interactions, including gravity, in a consistent theory. Despite the intrinsic difficulty of dealing with a theory that manifests itself at scales as high as the Planck mass, for more than 25 years there has been continuous progress in order to connect string theory and low-energy physics. This refers to extensions of the Standard Model of particle physics and cosmology that could lead to some observable implications.
