The Interuniversity Institute for High Energies, IIHE (ULB-VUB), was created in 1972 at the initiative of the academic authorities of both the Université Libre de Bruxelles and Vrije Universiteit Brussel. Its main topic of research is the Physics of elementary particles. The present research programme is based on the extensive use of the high energy particle accelerators and experimental facilities at CERN (Switzerland) and DESY (Germany) as well as on non-accelerator experiments at the South Pole. The IIHE plays an active role on the CMS experiment, which discovered the Standard Model scalar boson on 4th July 2012. The scalar boson was proposed in 1964 by François Englert, Robert Brout (deceased), both from ULB, and Peter Higgs, from the University of Edinburgh. The year 2015 was firstly marked by the Nobel Prize award for the discovery of neutrino oscillations, the second Nobel Prize award to particle physics in 3 years after the award in 2013 for the Brout-EnglertHiggs mechanism. The IIHE includes 19 members of the permanent scientific staff, 20 postdocs and guests, 31 doctoral students, 8 masters students, and 15 engineering, computing and administrative professionals. In September 2011 the yearly off-site CMS physics week was organised by the IIHE. Ongoing research are based on CMS, H1, Ice cube, Instrumentation, OPERA, Pheno, SoLid and many more. There is a range of Flemish and Brussels funds for strategic and applied research. Research at the IIHE is mainly funded by Belgian national and regional agencies, in particular the Fonds National de la Recherche Scientifique (FNRS) en het Fonds voor Wetenschappelijk Onderzoek (FWO) and by both universities through their Research Councils.Different workshops and conferences were organized like CMS physics week is organized outside Conseil Européen pour la Recherche Nucléaire (CERN) once per year, Third International Workshop on Top Quark Physics, etc.
