What is the "dark photons" and why physicists began to look for them again
In recent years, the amount of information on the properties and structure of the elementary particles that make up our entire universe, has increased considerably. This allowed the scientists to learn more about the structure of our world. However, one thing still does not give them any peace: dark matter. It confirms the theoretical calculations and even there is some evidence that it really should be. But "see" elementary particle that makes up dark matter has not yet succeeded. However, physicists at CERN (European Organization for Nuclear Research) suggests that the "foundation" of dark matter should be the so-called "dark photons". And scientists have begun to search for it.
What is dark matter?
Dark matter is so called does not matter what it black. This is an abstract concept, which suggests that this form of matter does not emit electromagnetic radiation. That is, in simple terms, the particles of which it is not fixed by any existing means of visual observation. Assumption of the existence of dark matter made based on numerous calculations and observations of astrophysical objects by gravitational effects they create. Roughly speaking, if you "put" in the behavior of the object all the known and visible to us elementary particles, "something not to be missed." And that "something" is not visible to us, but it has a gravitational effects, and called dark matter.
How to find dark matter?
It is this question CERN physics are given for many years in a row. One hypothesis is that dark matter is composed of elements, which interact with each other and the visible part of the material through the particles called "dark photons". "The dark photons" for dark matter are the same than normal photons are in the real world - the elementary particles. Except that they can not be seen.
This is interesting: why scientists can not detect dark matter?
However, in the NA64 series of experiments in 2016 - 2018, scientists tried to confirm the hypothesis of the existence of dark photons. During those tests in Superprotoh accelerator (SPS) occurred explosion energy beam. It was assumed that the dark photon can be detected by the energy that he "takes itself" after the explosion. Then nothing concrete could not be found, but now, after analyzing the available data, the researchers concluded that dark photons can have a much weaker strength of the interaction with matter than expected. Roughly speaking, the darker the photon must "take" several thousand times less energy in the explosion, and scientists simply "looking for him at other frequencies." So now physicists at CERN are going to repeat a series of experiments using a high-precision instruments.
The creation of new sensors should be completed by 2021. Maybe that's when we get the confirmation of the existence of dark matter. Well, not to miss this moment, we recommend to subscribe to our news channel in the Telegram. So you will learn the most news first.
