33. Dark Matter in the Sky

Francisco Prada (IAA (CSIC))

28. Search for dark matter in Antares and KM3NeT

Juan José Hernández-Rey (IFIC (CSIC-UV))

06/02/2018, 09:30

The results and prospects of dark matter search in the Antares and KM3NeT neutrino telescopes will be reviewed

18. High energy neutrinos from the Sun

Manuel Masip (Universidad de Granada)

06/02/2018, 09:50

Dark matter annihilation in the center of the Sun may imply a flux of high energy neutrinos observable at neutrino telescopes. This signal, however, faces an important background: secondary neutrinos produced in the showers of high-energy cosmic rays that reach the surface of the Sun. We argue that this Solar neutrino flux is correlated with the cosmic-ray shadow of the Sun measured by HAWC,...

31. Recent gamma ray dark matter searches with Fermi

Miguel Sánchez-Conde (IFT UAM/CSIC)

06/02/2018, 10:10

In this talk I will briefly describe some of the most recent work I have done within the Fermi LAT collaboration on the search for dark matter. Both WIMP and axion-like particle scenarios have been explored. Dwarf galaxies, galaxy clusters and the diffuse gamma-ray background are some of the astrophysical targets used in this search. I will end by discussing my group’s ongoing research on...

29. Unassociated Gamma-ray Sources as Targets for Indirect DM Detection with Fermi-LAT

Javier Coronado (IFT UAM/CSIC)

06/02/2018, 10:30

One of the predictions of the LCDM cosmological model is the hierarchical formation of structure, giving rise to DM halos and subhalos. When the latter are massive enough they retain gas (i.e. baryons) and become visible. This is the case of the dwarf satellite galaxies in the Milky Way. Yet, less massive subhalos may remain completely dark. Nevertheless, if DM particles are WIMPs, we expect...

32. Dark Matter searches in M15 galactic globular cluster

Camilla Maggio (Universitat Autònoma de Barcelona & CERES-IEEC)

06/02/2018, 10:45

The MAGIC telescopes observed the galactic globular cluster M15 for an amount of ~150 hours during 2015 and 2016. This large data set can be used to search for Dark Matter (DM) signals from this source. The interest of this work lies in the fact that globular clusters are among the oldest objects in the Universe (M15 is one of the oldest GCs in the Milky Way) and the study of their DM...

13. Where is SUSY DM?

Sven Heinemeyer (CSIC (Madrid, ES))

06/02/2018, 11:25

We combine astrophysical data with LHC measurements and searches, low energy and flavor experiments to analyze the DM candidate in various SUSY incarnations. We obtain predictions for the prospects of DM direct detection experiments and LHC DM searches.

22. Interplay of LHC SUSY searches and Dark Matter detection.

Mario E. Gomez (Universidad de Huelva)

06/02/2018, 11:45

The requirement that the Lightest SUSY particle (LSP) satisfies the cosmological condition to be a Dark Matter(DM) candidate imposes some relation among SUSY particles. We explore the consequences of these relations on the framework of SUSY models with Grand Unification, finding that LHC searches and DM searches can be complementary.

24. Sterile neutrino portal to Dark Matter: The global U(1)_(B−L) case

Miguel Escudero (IFIC-University of Valencia)

06/02/2018, 12:05

In this talk I will discuss the possibility of the dark matter being of leptonic nature within a local and a global $U(1)_{B-L}$ symmetry breaking scenario where the neutrino masses are generated via the type-I seesaw mechanism. I will argue that the thermal dark matter possibility within a local $U(1)_{B-L}$ seems unlikely due to the strong constraints from lepton and hadron colliders....

25. Ultra-light vector field dark matter

Antonio L. Maroto

06/02/2018, 12:20

Bosonic fields with very small masses, around $10^{-22}$ eV have been proposed as potential dark matter (DM) candidates. Unlike standard cold dark matter (CDM) particle models, ultra-light dark matter is more adequately described in terms of coherent fields on cosmological scales. In the scalar case, these models are known to suppress structure formation on sub-galactic scales, thus...

23. Unified Halo-Independent Formalism for Direct Detection Experiments

Samuel Witte (IFIC, University of Valencia)

06/02/2018, 12:40

In this talk I will present a new formalism that quite generically allows for the comparison of direct dark matter detection data in a halo-independent manner. This formalism, based on theorems from convex geometry, effectively eliminates all caveats that had limited the applicability of previously developed halo-independent methods; for example, halo-independent comparisons can now be made...

21. Cosmogenic production of tritium in dark matter detectors

Susana Cebrian (Universidad de Zaragoza)

06/02/2018, 12:55

The direct detection of dark matter particles requires ultra-low background conditions at energies below a few tens of keV. Radioactive isotopes are produced via cosmogenic activation in detectors and other materials and those isotopes constitute a background source which has to be under control. In particular, tritium is especially relevant due to its decay properties (very low endpoint...

27. Columnar recombination and directional nucleus reconstruction

Diego Gonzalez Diaz (Universidade de Santiago de Compostela (ES))

06/02/2018, 13:15

Columnar recombination is one of the most recent and intriguing ideas to overcome the neutrino floor in future dark matter experiments, performing neutrino physics through the coherent-interaction channel, or advance in fast neutron detection, with pointing accuracy.

At the moment, liquid-based detectors have been unsuccessful at finding any signature related to it, but the phenomenon is...
