14. New Directions in Direct Dark Matter Searches

Paolo Panci (Institut d'Astrophysique de Paris)

Direct searches for Dark Matter (DM) aim at detecting the nuclear recoils arising from a scattering between DM particles and target nuclei in underground detectors. Since the physics that describes the collision between DM particles and target nuclei is deeply non-relativistic, in the first part of this seminar I’ll review a different and more general approach to study signal in direct DM...

1. A halo-independent lower bound on the dark matter capture rate in the Sun from a direct detection signal

Dr Juan Herrero-Garcia (KTH)

We show that a positive signal in a dark matter (DM) direct detection experiment can be used to place a lower bound on the DM capture rate in the Sun, independent of the DM halo. For a given particle physics model and DM mass we obtain a lower bound on the capture rate independent of the local DM density, velocity distribution, galactic escape velocity, as well as the scattering cross section....

10. XENON100 and XENON1T

Jan Conrad (KTH Royal Institute of Technology (SE))

I will review recent XENON100 results and XENON1T status.

17. Halo-independent tests of direct detection signals

Stefan Vogl (University of Stockholm)

From an assumed signal in a Dark Matter (DM) direct detection experi- ment a lower bound on the product of the DM–nucleon scattering cross section and the local DM density is derived, which is independent of the local DM velocity distribu- tion. This can be combined with astrophysical determinations of the local DM density. Within a given particle physics model the bound also allows a...

2. New directional signatures from the non-relativistic effective field theory of dark matter

Bradley Kavanagh (IPhT - CEA/Saclay)

21/09/2015, 12:15

The framework of non-relativistic effective field theory (NREFT) aims to generalise the standard analysis of direct detection experiments in terms of spin-dependent (SD) and spin-independent (SI) interactions. I will show that a number of NREFT operators lead to distinctive new directional signatures, such as prominent ring-like features in the directional recoil rate, even for relatively low...
