Researchers Find More Evidence for the Higgs Boson | Smart news

July 4, 2012. In addition to being the 236th birthday of the United States, physicists announce that they have found solid evidence of the Higgs boson, an elusive particle that gives mbad to others elementary particles of the universe. It was one of the most important achievements in physics in the last century, and it took the construction of the Large Hadron Collider, the giant particle accelerator based outside Geneva, in Switzerland, to test it. After this triumph, the physics community was convinced that more discoveries would come from CERN. But, literally, quadrillions of proton collisions in the collider later, nothing new has emerged. Now, after sifting through years of data, researchers working on the LHC ATLAS experiment have announced that they could confirm something new: the disintegration of the Higgs boson produces bottom quarks, supporting a theoretical model of physics.

According to a press release, the Higgs sighting in 2012 was incomplete. While the observation of a Higgs boson is currently not possible, the detection of bits in which the particle decays is something that the particle accelerator can do. At that time, two predicted particles called W and Z bosons were observed, which is expected in about 30% of the decaying Higgs bosons. But researchers have not seen the expected particles 60% of time-based quarks.

Or at least, they thought. The problem, explains the Wire is that they saw some background quarks, just too much of them; the collider produces a lot of background quark through various interactions in addition to the proton currents that it was designed to snap one into the other. It was therefore extremely difficult to determine if a low quark detected in the LHC came from a decomposing Higgs boson or elsewhere. That's why it took scientists so long to reach the point of reasonable certainty that some of the lower quarks that they observed came from the disintegration of the Higgs. By examining all the data since 2011 and using new badytical techniques like deep artificial neural networks and machine learning, they finally found statistically significant evidence of Higgs-generated background quarks.

"This is the first time we see the coupling of Higgs John Huth, a particle physicist from Harvard University who is working on the ATLAS experiment, tells Ryan F. Mandelbaum to Gizmodo . "We thought it would happen, but until we saw it, we would not know for sure that it was coupled with quarks that way."

Although the discovery is a triumph of badysis and another confirmation that we have probably found the Higgs boson, it is also slightly disappointing. This is because it fits well into the standard model, with which physicists have been working since the early 1970s. Although the model explains a lot about particle physics, it has some gaping holes. For example, it does not address gravity or do not explain dark matter. Since the LHC was lit, researchers had been hoping for evidence of "weird" particles that would break or expand the standard model or confirm supersymmetry, an addendum to the model that helps explain the mbad. It just did not happen, at least not yet.

For the time being, physicists may have to wait a few more years before the laws of nature are rewritten. The LHC is undergoing a series of power upgrades that will be completed in 2026 and when it will be turned off on the accelerated particle accelerator, this could lead to the kind of strange science that the terrain needs to overtake the l? John Hughes's fiercest imagination. ] Like this article?
