An elusive Higgs boson decay was finally discovered



The Higgs boson failed – but that's good.

Physicists have discovered that the elementary particle breaks down into two bottom quarks, exotic, short-lived particles that frequently collide with high-energy particles. The elusive process was eventually observed six years after the discovery of the Higgs boson by physicists at the Large Hadron Collider at CERN in Geneva. Researchers from two LHC experiments, ATLAS and CMS, also reported on their findings in a seminar that took place on August 28 at CERN.

Scientists can not directly prove the Higgs boson. Instead, they discover the debris that arises when the Higgs disintegrates into less massive particles. It is expected that the Higgs boson will split into two bottom quarks over half the time. So far, however, scientists have not been able to elucidate the process because other mechanisms can produce bottom quarks and mimic Higgs decay ( SN: 9/3/1

6, p. 13 ). Scientists have previously seen that the Higg breaks down into other types of particles, including photons, a process that has fewer problems with Higgs impersonators.

With the unveiling of the Higgs boson in 2012, physicists filled the last missing part of the Higgs Standard Model, the theory of the fundamental components of matter ( SN: 7/28/12, p. 5 ). But the physicists still want to know more about the inner workings of the Higgs.

The Standard Model predicts how many times the Higgs should disintegrate into different types of particles. Bottom quarks are one of six types of quarks in the standard model, each with different properties, such as mass and electric charge. While the lightest quarks form ordinary particles such as protons and neutrons, bottom quarks are relatively heavy and rare.

Physicists want to measure the different ways in which the Higgs boson decays to see if the rates are in line with expectations. If not, it could mean that something is wrong with the theory. But the new results confirmed the standard model.
