Using the European Hadron Collider to collide for the first time, no mini black hole was found

According to a report on December 21, Beijing time, according to the report of the United States Wired magazine, the first large-scale Hadron Collider (LHC) collision experiment in the United States continued to surprise people. Last week, the task team of the compact muon spiral magnetic spectrometer (CMS) announced that they had submitted a paper to the Physics Letters magazine describing the experimental process of certain forms of string theory.

According to the mission team, if this form of string theory is correct, the Large Hadron Collider should be able to generate mini black holes, but these black holes will disappear instantly instead of devouring the earth as some people fear. However, the analysis of the data obtained by the CMS detector shows that the signal of the black hole energy attenuation obviously does not exist.

What is string theory?

String theory attempts to uncover a mystery of physics, that is, why the two major theories of physics, quantum mechanics and theory of relativity, are basically incompatible. String theory assumes that there are additional dimensions beyond the four-dimensional space, thus combining these two theories. A basic view of string theory is that the basic units of nature are not particles such as electrons, photons, neutrinos, and quarks. These things that look like particles are actually closed loops of small strings (called closed strings). Different vibrations and movements of the closed strings produce a variety of elementary particles.

We can't see these closed strings with the naked eye, because they are tightly wrapped in a small radius that is difficult to access with normal energy. In a string theory-the CMS detector task team called it the ADD mode, because it was proposed by three scientists including Akani Hamid, Timopoulos, and Deval-this unity has The result of gravity. Normally, gravity is very weak compared to other forces. The reason is that only when the energy is several orders of magnitude of the Large Hadron Collider, can it be unified with the residual force.

But in the ADD mode, gravity only looks weak, because part of it is trapped in the remaining dimensions, which reduces the energy to within the range of the Large Hadron Collider. If everything develops according to the process predicted by the ADD model, particles colliding with energies higher than this limit should be within a distance less than the space occupied by the extra temperature. Once this happens, they will feel all the gravity and immediately merge into a mini black hole. In fact, because it is too small, the black hole almost instantly decays via Hawking radiation.

No energy attenuation signal of mini black hole found

This decay process is as clear as the particle jet. Physicists have said that people should not miss this process. However, we usually mistake other things for black holes. Interactions dominated by quantum chromodynamics will also produce jets of a certain frequency, so black hole events must appear to stand out in this context. This is exactly what the latest analysis looks for. The CMS detector task team simulated the condition of the ejection of string theory and quantum theory to exclude it, thereby saving the ejection event-this does involve the same modeling software used by TSA scanner assessors.

Next, they used energy within the energy spectrum of the Large Hadron Collider to analyze the background jet levels generated by quantum chromodynamics. These energies were too low to produce black holes. Later, they extended the analysis to the range of energies where black holes should appear, to see if any signals are obvious in this context. As a result, they did not make any discovery in this regard. The CMS detector task team concluded: "We can exclude the possibility of generating black holes at a minimum mass of 3.5 to 4.5 eV to evaluate the multidimensional Planck scale at a 95% confidence level."

This result is also of great significance to the research in fields other than string theory. Mini black holes are not the only hypothetical material that scientists predict energy decay to ejection, so the lack of a signal above the background also places some serious limitations on physics itself. Another advantage is that the energy involved completely deviates from the capabilities of the Large Hadron Collider. In this way, even if the older collider collided with the Large Hadron Collider to generate Higgs particles, we can obviously obtain some useful physics achievements from the experiment with the Large Hadron Collider.

Contrary to some reports, this research experiment does not mean that string theory is going to extinction, but it only highlights the mode of predicting black holes under these energies. Excluding certain patterns is a key step in narrowing the possibilities. Most theoretical concepts have many possible models, and string theory is no exception. In fact, it is entirely possible that only the ADD mode exists because physicists are looking for or capable of experimenting with materials in the Large Hadron Collider.
