By Zeeya Merali TWO blogging physicists made a stir earlier this year when they divulged rumours that the Higgs boson – the most-wanted particle in physics – may have been spotted in Batavia, Illinois. Follow-up results revealed this week leave those hints as tantalising as ever. In the standard model of particle physics, the hypothetical Higgs boson is needed to give all other particles their mass. More exotic “supersymmetric” theories, on the other hand, predict a family of Higgs bosons, each with a different mass. In March, New Scientist reported that two independent rival groups using the Tevatron accelerator at Fermilab,
