  1. 34. Self-interacting dark matter for solving small scale problems
    Dr Camilo Alfredo Garcia Cely (Université Libre de Bruxelles)
    23/03/2017 17:00
    Theory
    Ordinary
    Dark matter self-interactions are a well-motivated solution to the core-vs-cusp and the too-big-to-fail problems. They are commonly induced by means of a light mediator, that is also responsible for the dark matter freeze-out in the early universe. Motivated by the fact that such scenario is constrained to corners of the parameter space where the SM and the dark sector are decoupled, I...

  2. 64. Ultralight axion dark matter
    Prof. Lam Hui (Columbia University)
    23/03/2017 17:20
    Theory
    Ordinary
    We will discuss the physical motivations for and implications of ultralight axion dark matter, with mass of the order of 10^{-22} - 10^{-20} eV.

  3. 21. Dark Matter Search Results from the PICO-60 C$_3$F$_8$ Bubble Chamber
    Dr Guillaume Giroux (Queen's University)
    23/03/2017 17:40
    Experiment
    Ordinary
    The PICO collaboration searches for dark matter particles using superheated fluid detectors, or bubble chambers. These detector can be made inherently insensitive to gamma and beta radiation, while the additional background suppression required to obtain sensitivity to the elusive dark matter signal is achieved with the acoustic signature of the bubble nucleation that allows the identification...

  4. 113. Axion-H portal-seesaw: solving 5 problems
    Carlos Tamarit (Institute for Particle Physics Phenomenology, Durham UK)
    23/03/2017 18:20
    Ordinary
  5. 13. Axion-like particles motivated by astrophysics
    Prof. Sergey Troitsky (INR, Moscow)
    23/03/2017 18:40
    Theory
    Ordinary
    Observations of ensembles of distant gamma-ray sources suggest anomalous transparency of the intergalactic space for energetic gamma rays, which may be understood if the photons mix with an axion-like particle with well-constrained parameters. I briefly review these observations together with implications of the axion-like particle for physics, astrophysics and cosmology.
