Scientists from Harvard University and the University of Liverpool have announced that by 2030, we should have a better understanding of the mass ratio of the three types of neutrinos. Neutrinos are particles of extraordinary ubiquity that have an influence on the shape of the universe, making them incredibly interesting to scientists.
In an article published in “Physical Review X,” researchers C.A. Argüelles, P. Fernández, I. Martínez-Soler, and M. Jin describe their analyses on the sensitivity of experiments studying neutrinos. In their studies, scientists use water or ice and Cherenkov radiation to investigate these particles.
Neutrinos come in three types: electron, muon, and tau neutrinos. They are produced in various events, such as supernova explosions, and scientists believe that their type is determined at the moment of their creation. However, we know that neutrinos can change their type.
Scientists study neutrinos both generated in particle accelerators and those produced by cosmic radiation colliding with atoms in the Earth’s atmosphere. These studies are often conducted in water tanks or ice, where photodetectors are placed to record the flashes of light produced during neutrino-atom collisions.
The authors of the latest analysis focused on this research method. Considering the current sensitivity of such experiments and the prospects for their development, researchers believe that within the next six years, it will be possible to determine the masses of all types of neutrinos.
Frequently Asked Questions (FAQ)
1. What are neutrinos?
Neutrinos are elementary particles with very small mass and no electric charge. The universe is filled with neutrinos that are produced in various phenomena, such as supernova explosions.
2. What are the three types of neutrinos?
The three types of neutrinos are electron, muon, and tau neutrinos. Each type of neutrino has a different mass and can change its type during its journey through space.
3. How do scientists study neutrinos?
Scientists study neutrinos by using special experiments that observe the collisions of neutrinos with atoms in the Earth’s atmosphere or in particle accelerators. These experiments often involve the use of water or ice and photodetectors to detect the light emitted during collisions.
