Spin doctors

| 8 May 2008 Theorists and experimentalists aren't always of the same opinion. There is one thing on which opinions aren't polarised though, and that is polarisation. Polarisation is a special characteristic of a particle bunch – a sort of measure of the particles’ combined spin – that, when studied in the right sort of detector at the ILC, is supposed to give clues and answers on phenomena like the Higgs, supersymmetry or searches for new physics and extra dimensions. To study the collisions, and also to understand polarisation better, a few groups of a total of about 30 people around the world are designing and building polarimeters that measure the degree of polsarisation of the particles before and after collisions. They have just had their first 'collaboration' meeting at DESY in Zeuthen, near Berlin, Germany. Category: Around the World | Tagged: , , , , , ,
