Higgs-Boson likelihood grows stronger

GENEVA, SWITZERLAND – Scientists from Cern officially presented their latest findings on the long-sought Higgs-Boson Thursday at a conference, saying that the massive amount of data treated since the “discovery” particle was announced in July 2012 makes it appear increasingly likely that this is a Higgs boson. “The preliminary results with the full 2012 data set are magnificent and to me it is clear that we are dealing with a Higgs boson though we still have a long way to go to know what kind of Higgs boson it is,” says Cern spokesperson Joe Incandela.

Higgs boson is the particle “linked to the mechanism that gives mass to elementary particles”, Cern notes in a statement; it was popularly and not quite accurately referred to in the press for months as the God particle.

Two and a half times more data has been processed since last July. “It remains an open question, however, whether this is the Higgs boson of the Standard Model of particle physics, or possibly the lightest of several bosons predicted in some theories that go beyond the Standard Model. Finding the answer to this question will take time,” Cern reports. “Whether or not it is a Higgs boson is demonstrated by how it interacts with other particles, and its quantum properties. For example, a Higgs boson is postulated to have no spin, and in the Standard Model its parity – a measure of how its mirror image behaves – should be positive. CMS and ATLAS have compared a number of options for the spin-parity of this particle, and these all prefer no spin and positive parity. This, coupled with the measured interactions of the new particle with other particles, strongly indicates that it is a Higgs boson.”
