Scientists have stepped closer to understanding the mysteries of matter, Scientists have measured the nature of neutrons as the main particles in the universe more accurately than ever before.
The research is part of the study of why matter remains in the universe, which is why all the antimatter created in the Big Bang doesn’t just eliminate the question.
The team, which included the Appleton Rutherford Laboratory, the Appleton Rutherford Laboratory in England, the Paul Sherrer Institute (PSI) in Switzerland and a number of other institutions, examined whether neutrons acted as “electric compasses” or not.
Neutrons are believed to have a slightly asymmetrical shape that is slightly positive at one end and slightly negative at the other, similar to a magnetic equivalent.
This is what is called the electric dipole moment (EDM) and this is what the team is looking for.
This is an important piece of the puzzle in the riddle of why matter remains in the universe, because scientific theories about why matter also predicts that neutrons are more or less influenced by the property of the “electric compass”. Scientists have stepped closer to understanding the mysteries of matter.
The team of physicists found that neutrons have a much smaller EDM than predicted by various theories about why matter remains in the universe; This makes these theories less likely to be true, so they need to be modified or new theories can be discovered.
In fact, it has been said in the literature that this EDM measurement, considered a set, might have disproved more theories over the years than any other experiment in the history of physics.
We are looking for it. We find that the “electric dipole moment” is smaller than previously thought. said the researcher.
This helps us to exclude theories about why matter remains because the theories that govern the two are interconnected.
Experiments combine various modern technologies, which everyone must implement simultaneously. We are pleased that the tools, technology and expertise developed by RAL scientists have helped push the boundaries of this important parameter. Scientists have stepped closer to understanding the mysteries of matter.
This experiment combines techniques from nuclear physics and low energy, including laser-based optical magnetometry and quantum spin manipulation.
By using multidisciplinary tools to measure the properties of neutrons very accurately, we can investigate questions related to the physics of high-energy particles and the basic nature of symmetry that underlies the universe.
Every electric dipole moment that a neutron has is small and therefore very difficult to measure. Previous measurements by other researchers have confirmed this. In particular, the team must make a major effort to keep the local magnetic field very constant during the last measurement.
For example, every truck on its way to the institute disrupts the magnetic field on a scale that will be important for the experiment, so this effect must be compensated during measurements.
In addition, the number of neutrons observed must be large enough for the dipole to be measured. Measurements were continued for two years. The so-called ultra-cold neutrons are measured, that is, neutrons with a relatively slow speed. Scientists have stepped closer to understanding the mysteries of matter.
Every 300 seconds, a group of more than 10,000 neutrons is intended for experiment and examined in detail. The researchers measured a total of 50,000 such grapes.
Recent research findings have supported and improved the results of its predecessors: New international standards have been set.
The EDM size is still too small to be measured with tools that were previously used. As a result, several theories that try to explain the excess of matter are less likely.
The technique originally developed for the first EDM measurements in the 1950s has led to global changes such as atomic clocks and NMR scanners and has maintained its enormous and long-lasting effects in the field of particle physics to this day.
