Finding Higgs particles with mass in that. The search culminated in 2012 with the discovery, by the ATLAS and CMS collaborations, of a Higgs-like particle with mass close to 125 GeV, confirmed more. Scientists on experiments at the Large Hadron Collider declared the discovery of the Higgs boson in 2012.Įditor's note: This article has been updated to reflect the discovery of the Higgs boson. First, supersymmetry (for experts: more specifically, focus point supersymmetry) predicts that the Higgs particle mass should lie in the range 120-130 GeV. Other particles-such as the photons of light-are immune to the field: They do not slow down and remain massless.Īlthough the Higgs field is not directly measurable, accelerators can excite this field and “shake loose” detectable particles called Higgs bosons. Such particles would behave like massive particles traveling at less than light speed.
But, how do massive particles arise? Higgs proposed that the vacuum contains an omnipresent field that can slow down some (otherwise massless) elementary particles-like a vat of molasses slowing down a high-speed bullet. In 1964, one of the British physicists Peter Higgs was working on the particles at Edinburgh University, he predicted that in addition to the particles the scientists already knew, there must be another one. In Einstein's theory of relativity, there is a crucial difference between massless and massive particles: All massless particles must travel at the speed of light, whereas massive particles can never attain this ultimate speed. The Higgs Boson particle is an elementary particle predicted by the standard model and its existence was proved in 1912 by ATLAS and CMS. The origin of mass seems to be related to this phenomenon. In 1964, Englert and Higgs (in separate papers) proposed the theory that predicted the.
The particle is a carrier of an all-pervading quantum field, known as the Higgs field, which gives other elementary particles their mass. The Higgs is a vital ingredient in the Standard Model of physics.

It is indeed “noisy” and full of virtual particles and force fields. The Higgs boson plays a prominent role in the Standard Model. Explaining the connection, I am reminded of the puzzler, “If sound cannot travel in a vacuum, why are vacuum cleaners so noisy?” This riddle actually touches on a profound insight of modern physics: the vacuum-or empty space-is far from empty. The Higgs boson, a fundamental particle predicted by theorist Peter Higgs, is key to understanding why elementary particles have mass. Starting with the theoretical background framework, the Standard Model of particel physics, the Higgs field will be introduced as an addition.
