The Astroparticle Physics International Forum (APIF)

The Astroparticle Physics International Forum of the OECD Global Science Forum

The OECD Astroparticle Physics International Forum (APIF) brings together officials and representatives of funding agencies of countries that make significant investments in astroparticle physics research.  It is a venue for information exchange, analysis, and coordination, with special emphasis on strengthening international cooperation, especially for large programmes and infrastructures.  APIF members can address issues that are the special responsibility of funding agencies, for example, legal, administrative and managerial arrangements for international projects.  They may also consider matters such as access to experimental facilities and data, procurement of essential materials, and optimal use of resources on a global scale.  APIF is not a venue for discussing purely scientific matters, and it does not duplicate or replace established national and international processes for planning, prioritisation, funding, assessment or implementation of specific projects or programmes.

As of February 2012, the members of APIF are representatives of agencies of the following countries:

  • China
  • European Union
  • France
  • Germany
  • India
  • Israel
  • Italy
  • Japan
  • Korea
  • Netherlands
  • Spain
  • Switzerland
  • United Kingdom
  • United States 

Professor Roger Blandford of Stanford University, who does not represent any country or agency, and was elected by APIF members based on the recommendation of the OECD secretariat, has been chairing the committee since May 2017. 

APIF was established by the Organization for Economic Co-operation and Development’s Global Science Forum, which is a committee of senior science policy officials of OECD member and observer countries.  The Global Science Forum was acting on one of the final recommendations of its Working Group on Astroparticle Physics, whose report is available here.

Astroparticle physics marks the intersection of cosmology, astrophysics and particle and nuclear physics.  The scientific scope of the field extends over vast distance scales – from the realm of subatomic particles to the outer reaches of the observable universe.  While there is no universally accepted set of scientific issues that comprise astroparticle physics, APIF has chosen the following scientific scope for its work:

  • dark matter
  • dark energy
  • neutrino mass and neutrino mixing
  • proton decay
  • high-energy cosmic rays (including charged particles, gamma rays and neutrinos)
  • gravitational waves
