  1. 38. Results of the WIMP search with XENON1T
    Prof. Marco Garbini
    19/06/2018, 09:00

    Astronomical and cosmological observations indicate that a large amount of the energy content of the Universe is made of dark matter. The most promising dark matter candidates are the so-called WIMPs (Weakly Interacting Massive Particles).
    The XENON project, at the Gran Sasso National Laboratory (LNGS), consists of a double-phase time projection chamber (TPCs) using ultra-pure liquid Xenon as...

  2. 81. WIMPS and beyond --- Super-cool dark matter
    Prof. Thomas Hambye
    19/06/2018, 09:30

    After a very short review of the WIMP dark matter scenario and constraints, I will discuss another possibility to account for the necessary suppression of the number of dark matter particles during the early Universe radiation dominated era: "super-cool dark matter".
    This is based on the recent work, arXiv:1805.01473, in collaboration with A. Strumia and D. Teresi.

  3. 76. Bounds on Dark Matter annihilations from 21 cm data
    Dr Guido D'Amico (CERN)
    19/06/2018, 09:55

    The observation of an absorption feature in the 21 cm spectrum at redshift z≈17 implies bounds on Dark Matter annihilations for a broad range of masses, given that significant heating of the intergalactic medium would have erased such feature. The resulting bounds on the DM annihilation cross sections are comparable to the strongest ones from all other observables.

  4. 57. Exploring WISPy Dark Matter
    Prof. Joerg Jaeckel
    19/06/2018, 10:45

    Very light bosons, produced non-thermally in the early Universe are an intriguing possibility for the cold dark matter of the Universe.
    Particularly interesting candidates are axions, axion-like particles and hidden photons. This talk will discuss the current status of such light dark matter with a particular emphasis towards opportunities for its detection. We also venture to some more exotic...

  5. 48. Indirect DM searches
    Dr Marco Cirelli (CNRS LPTHE Jussieu)
    19/06/2018, 11:10

    I will briefly review the current status of searches for Dark Matter using cosmic rays, intended in a broad sense (charged particles, gamma rays, neutrinos, possibly the CMB and radio waves).
