Ten years of particle research, Tao Li Chunfeng watched the future- "Nature" published the latest results

At the time of the European Nuclear Research Center (CERN) large -scale strong sub -collision machine (LHC) announced on the occasion of the tenth anniversary of Higgs Boson, British "Nature" magazine published ATLAS (superconducting ring detectors) and CMS ( The latest research results of this basic particle attributes for the experimental group.

Before 2012, the Higgs Bolk was the most famous but most confusing particles in the entire Asian atomic world. It has long occupied the research center of the entire particle physics community. Because if the particles appear, the mystery of the origin of material quality will be revealed; if the particles do not exist, theoretically, all particles can only be required to have no quality without exception -this will undoubtedly contradict the current experimental observation, physics, physics If the scholars want to re -evaluate the discussion, the significance may not just be a theoretical modification, but a subversion.

But in July ten years ago, CERN's ATLAS and CMS experiment group announced that it discovered a particle with the expected attributes of Higgs Bose, which is known as "one of the biggest new discoveries in physics in the past 30 years or even 40 years. "". Since then, Higgs Boson has been detected by less than 30 times, allowing researchers to have the opportunity to verify whether their behavior meets the description of the standard model of basic particle physics.

Now, the two experimental groups have reported the analysis results involved in the production or decaying data of Higgs Bose in the second round of the large -scale collision (2015-2018). The main question of their research is how Higgs boson interacts with other basic particles. According to the theory of the standard model of particle physics, the interaction strength of any particle and Higgs boson is proportional to the quality of the particles.

Ten years of data allows the two experimental groups to estimate the interaction between Higgs Bolometer and the heaviest particles in a reasonable error. These particles include top quarks and bottom quarks, Z bipes and W boson,, and W Bolk,,,, τ τ τ. For all these particles, the data is consistent with the behavior of the basic particle physics standard model prediction, and the results are within the range of the experimental error.

Julia Zandridi, a scientist at Max Planck Institute of Physics in Germany, and his colleagues in a concept article have discussed the research progress in the past ten years (still to be proven) and the possible future possible Explore direction.

Scientists wrote: Ten years ago, it was discovered that Higgs Boson was a milestone in the field of basic physical interaction. In the theorist proposed to assume the in the second century, people really confirmed the existence of this particle. The significance of this discovery lies not only to discover a long -awaited new particle, but also provides the first direct evidence that proves that there is a new basic "field" around people.

The world has a long time to be famous for Higgs and has been indifferent. The point of view of the point of view is that the most important difference between the Higgs and the magnetic field is that if the magnetic source is removed, the magnetic field disappears; in contrast, the Higgs field is right anywhere. But in daily life, people had no way to perceive the Higgs field around us. Scientists reveal the only way to Higgs field to disturb it slightly. Just like throwing stones into the water, people finally saw ripples -Higgs Bolk is exactly the manifestation of this disturbance.

The progress in the past ten years is expected to continue until the next decade. Some key attributes of Higgs boson -such as self -coupling or coupling with lighter particles -still need to be measured and are expected to reveal the deviation of actual and theoretical. However, the current dataset may be at least in the next decade to promote our understanding of the physical attributes of Higgs Bolometer. These Higgs boson -related content also represents the research potential of future physics.
