Fabiola Gianotti to lead Cern particle physics research centre
In the LHC, which is awaiting relaunch with twice the power in spring next year, elementary particles are smashed together at close to the speed of light, creating billions of tiny “big bangs” and their aftermaths.
Gianotti in 2009 became project leader of the Atlas collaboration, one of two teams working separately to spot the Higgs in the LHC data. With her counterpart from the CMS team, she detailed the finding of the Higgs – named after the British physicist who predicted its existence in 1964 – before a global television audience in July 2012. The discovery brought a Nobel prize in 2013 for Peter Higgs, the British theorist, and François Englert, a Belgian physicist working on the same idea with two colleagues in the early 1960s and who also posited the existence of the boson.
Gianotti, an accomplished pianist who once considered a career in music, said she was honoured to be named to head the sprawling institute – which links 10,000 scientists on site and around the world – along the Franco-Swiss border outside Geneva. “CERN is a centre of scientific excellence and a source of pride and inspiration for physicists from all over the world, a cradle for technology and innovation, and a shining concrete example of scientific cooperation and peace,” she said.
When collisions in the LHC are resumed, scientists look for evidence to resolve other major scientific questions, including the dark matter thought to make up about a quarter of the universe, and dark energy, accounting for 70%.
