neutrino athere are three “flavors”say . No dear ? Not quite sure, some say. ‘Cause there can only be a fourth “flavor” consists of neutrinos. It’s what researchers call a sterile neutrino. An almost elusive neutrino. His brothers used to cross the street before physicists realize it. But that would be even more ghostly. only sensitive . Thus, unlike its brethren, the sterile neutrino itself not zero. It can even form a non-negligible part of the celebrity. which continues to elude researchers.
A few decades ago, a series of anomalous observations — particles that seem to have volatilized — motivated the implementation of several experimental projects aimed at cleaning up the sterile neutrino. Today, somefrom (United States) confirms this. The results of their experiments deviate from the theoretical predictions of the world. particle physics.
What did they actually observe? It all happened somewhere below 1,500 meters.(Russia). Protected against cosmic radiation. In double tank Fluid (Best) from Baksan’s experiment on sterile passages, approx. 26 discs 51. All bombarded by an electron neutrino source. To convert some of the gallium 71. But that’s 20 to 24% less germanium than models predict. Since these numbers are approximate to those measured in the past and every precaution has been taken to avoid experimental errors – for example in the operations of the counting system – the explanation must be found elsewhere. And maybe in the sterile neutrino.
Los Alamos is the leading American institution collaborating on an intriguing study with compelling results that points to a new yet unconfirmed fundamental particle: sterile. #neutrino. https://t.co/oW8SnV8j7S

sterile neutrino or something
What you need to know to understand better is that neutrinos can change in some way. “flavor” along the way, according to the phenomenonwhat physicists call oscillation. Thus, the measured gap can be evidence that oscillations occur between electron neutrinos and electron neutrinos. . “Our results are very exciting”In the comments, analyst Steve Elliott said that a from Los Alamos National Laboratory.
“This confirmsWe’ve seen in previous experiments But it’s not clear what that means.The researcher continues. Because there may be other explanations for this germanium 71 production gap. Among the most likely, there may be an error in the estimation of the electron neutrino cross section. In other words, the theory could have overestimated the probability of an interaction occurring between the electron neutrino and gallium. “It would be equally interesting if our results led to the conclusion that the Standard Model and particle physics are poorly understood”Steve Elliott emphasizes.
Physicists are already considering new experiments to get to the bottom of it and hope to finally understand where this discrepancy between observations and theory really comes from. On slightly different grounds. To someoneeg higher.
