The Invisibles21 virtual Workshop will take place from May 31 to June 4, 2021, after the Invisibles21 School. This is the annual meeting of the Horizon 2020 Marie Curie ITN network HIDDeN, which continues the series of “Invisibles” events started in 2012 (Horizon 2020 Marie Curie ITN network Invisibles, Horizon 2020 Marie Curie ITN network Elusives and the Horizon 2020 RISE network InvisiblesPlus).

The focus of the workshop will be on "Neutrinos, Dark Matter, Axions and other Elusives".

  • Invisible particles: neutrinos, axions, WIMPs;
  • Invisibles at colliders: Beyond Standard Model searches;
  • Invisibles in astrophysics and cosmology: dark matter searches, black holes, gravitational waves and the origin of Cosmic Rays.

Note: The workshop talks will be streamed and available afterwards through the HIDDeN YouTube channel: 

Talks are by invitation only, except for PhD students: they are welcome to apply during the registration process to participate in the PhD forum with a 5 min. plenary talk complemented with a poster on the same subject. Everyone is also welcome to request a poster contribution. Poster contributions may be accompanied by a video presentation of it of up to 10 mins. 

Important dates 

  • April 12th, 2021: Deadline for student applications for "PhD Forum Talk + Poster Contribution". Applications for "Poster Contribution" only may also be accepted afterwards.

  • May 3rd, 2021: Registration deadline.

The Invisibles21Workshop is organised in the context of the Horizon 2020 funded project HIDDeN. HIDDeN is a European ITN project (H2020-MSCA-ITN-2019//860881-HIDDeN) focused on revealing the (a)symmetries we have yet to discover, hence hidden (a)symmetries, and the particles on which they act, in particular the invisible sector, made of neutrinos, dark matter and other elusive particles. It has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 860881-HIDDeN”. 

Conference secretariat: Rebeca Bello, Chabely Prats, Mónica Vergel.
