Human sources: the main sources in charge of creating artificial neutrinos are nuclear power plants.They escape freely from the solar nucleus through the Earth. The Sun: it is the most important source in neutrinos production, and they are born from it through the processes of beta disintegration of its nucleus reactions.The oscillation that occurs in neutrinos directly implies that they have a non-zero mass. They have the ability to pass from one family of neutrinos to another through a process known as neutrino oscillation. There are three types of neutrinos: electronic neutrinos ( ne ), muonic neutrino ( nm ) and tauonic neutrino ( nt ) plus their respective antiparticles. This type of particle is an essential part of all the blocks and everything that exists in the universe. The neutrino is an elementary particle which means that it cannot be subdivided into other particles. They are not affected in any way by strong electromagnetic or nuclear forces, but they are affected by weak nuclear and gravitational forces.They have little interaction with matter.They can also be created by beta radioactivity.They are emitted by the stars and by the atmosphere.They don’t have any kind of electric charge.It is very difficult to detect even though there are millions of them.They interact with practically nothing in the universe.They are very small particles, almost like electrons.They are as fast as the speed of light.The main characteristics of neutrinos are as follows: McGuire published the article “Free Neutrino Detection: A Confirmation” which was rewarded with the 1995 Nobel Prize. In 1956, Clyde Cowan, Frederick Reines, F. Because of its “ghostly” properties, the first experimental detection of neutrinos had to wait 25 years after it was first discussed. Pauli theorized that an undetected particle was carrying the observed difference between the energy and angular momentum of the initial and final particles. The neutrino was first postulated in December 1930 by Wolfgang Pauli to explain the energy spectrum of beta disintegrations, the decomposition of a neutron into a proton and an electron. Since then, the universe has continuously expanded and cooled, and neutrinos have continued. Our floor is broadly similar to those found in the literature, but differs by almost an order of magnitude in the sub-GeV range, and above 20 GeV.What we know today from science is that most of the neutrinos that float was born about 15 billion years ago, shortly after the universe was born. The technique is based on the derivative of a hypothetical experimental discovery limit as a function of exposure, and leads to a neutrino floor that is only influenced by the systematic uncertainties on the neutrino flux normalizations. Here we propose to define the neutrino floor as the boundary of the neutrino fog, and develop a calculation free from these assumptions. The downside of current methods of deriving the neutrino floor are that they rely on arbitrary choices of experimental exposure and energy threshold. As a consequence, some have recently advocated for calling it the “neutrino fog” instead. However, it has been known for some time that the neutrino floor is not a hard limit, but can be pushed past with sufficient statistics. It is commonly interpreted as the point at which dark matter signals become hidden underneath a remarkably similar-looking background from neutrinos. The neutrino floor is a theoretical lower limit on WIMP-like dark matter models that are discoverable in direct detection experiments.
