Florida State University physicists think they have a solution to uncommon occurrences of unusual degeneration of a subatomic particle called a Kaon that were reported in 2014 by researchers in the KOTO experiment at the Japan Proton Accelerator Research Complex.
FSU Associate Professor of Physics Takemichi Okui and also Assistant Professor of Physics Kohsaku Tobioka released a brand-new paper in the journal Physical Review Letters that suggests that this degeneration is really a brand-new, brief particle that has actually stayed clear of discovery in comparable experiments.
“This is such a rare disintegration,” Okui claimed. “It’s so rare, that they should not have seen any. But if this is correct, how do we explain it? We think this is one possibility.”
Kaons are fragments made of one quark and also one antiquark. Researchers research study just how they work– that includes their degeneration– as a method to much better comprehend just how the globe functions. But in 2014, scientists in the KOTO experiment reported 4 circumstances of a certain unusual degeneration that need to have been as well unusual to be discovered yet.
This monitoring violates the standard model of physics that clarifies the standard essential pressures of the world and also categorizes all recognized fundamental particles.
According to their estimations, there might be 2 opportunities for brand-new fragments. In one situation, they recommend that the Kaon may degeneration right into a pion– a subatomic particle with a mass regarding 270 times that of an electron– and also some type of unnoticeable particle. Or, the scientists in the KOTO experiment might have observed the manufacturing and also degeneration of something entirely unidentified to physicists.
Researchers in Japan are performing an unique information go to validate whether the previous monitorings held true discoveries of brand-new fragments or merely sound.
“If it’s confirmed, it’s very exciting because it’s completely unexpected,” Tobioka claimed. “It might be noise, but it might not be. In this case, expectation of noise is very low, so even one event or observation is very striking. And in this case there were four.”
