The most energy neutrine ever seen makes Mediterranean splash
A “ghost particle” found by a Mediterranean detector is 30 times more energy than a neutrino seen by a neutrino

In a given maritime sea seaside sea at the Maritime Sea, for a few hours of February 2023, it was a night like any other, until it was like any other bright azur, until the eyes of humans are invisible. through dark water. The event showed something extraordinary: perception The most energy-energy particle of the type of type measured so far.
It was a card to call a cosmic flash neutrinoIt’s from a childhood and usually light “Ghost particle“So it’s hard to interact with the ordinary topic that makes up our world. A neutrino can spend the lead from a year without harmless. And each second of 100 trillions of particles (most of them have issued our sun) the body. This makes it difficult to catch-But, otherwise the potential messengers of astrophysical processes hidden, obscured by the stars of the stars and the dust of galaxies.
This finds and characterization comes mainly in KM3NET duplicate European cooperation, A wide neutrino telescope It is still under construction and once built, Mediterranean will be used around a cubic mile of marine water, as the basis of his two different detectors. However, with its incomplete situation, the project has given an amazing result – it has a neutrino beyond the Galaxy, a neutrino and unprecedented power beyond.

“It is in a completely unexplored energy region, 30 times higher than the previous neutrino observation,” Paschal Coyle said, the Neutrino Physicist Neutrino in the National Center for Scientific Center and members of the Km3net team, at the press conference Tuesday.

Km3Net’s two detectors, dedicated to more atmospheric atmospheric atmospheric. The other, a double arca, is located nearly 3.5 kilometers on the Sicilian coast and is designed to detect astrophysical neutrino, observing the waste of rare interactions with water molecules.
“Many things have so much energy, so hard, you get this horrible particle spray,” says Kate Scholberge, who examines Neutrinos at Duke University, but not participating in new research. “It doesn’t interact much, but when it does, it makes a huge spracular spraying of all kinds of particles. And it’s the light of these particles you see.”
The Neutrino hit found was only 21 from the 230 anticipated Arca detection lines. Neutrino was based on an external water molecule of the detector, creating a burst of particles, among other things High energy hill-No this kind of subatomical particle, but 200 times heavier. Muon then created his fragmented waste, the rumor of the Pale Pale Photo of Telltale Pale was duplicated in the Cherenkov radiation on Arca instruments. By analyzing this light, physicists were able to rebuild the submarine of Muon, estimated the energy of the original neutrino and estimated its origin to a specific region of space.

Researchers estimate that neutrin’s energy is 220 PETS among the electrons, 30 times higher than the most energy neutrine identified before new observations. At the press conference that people conceptualizes, Aart Heijboer, Nikhef is a physicist of Nikhef National Institute of Nikhef, in the Netherlands, and an author of a new study offered the image of a ping-pong ball. The newly detected neutriny was stored in a lot of energy packed in a single subatomical particle. Or to compare that scientists of particle accelerators could be built: “It is 1,000 more times more than we could produce on the ground,” Bryan Ramson, the Nutrinist Laboratory of Nutrine Laboratory of Nutrine Laboratory of Illinois Fermi Accelerator. involved in new research.
Detection is tantalized, but also creates more questions than answer. Km3net is joining a long neutrino telescope Icecube 2011. Since he has been collecting data next to the South Pole. Icecube was designed to catch this type of high-energy neutrino as effective as Km3net Observation to keep the current record He assumed the energy of the new Km3net discovery, which has raised eyebrows among some experts.
“It’s my first impression that this is very unexpected. And how can I have something (similar) before Icecube?” Physicist of the current spokesman of Izecube Institute in Georgia Institute and Icecube.
In addition, Km3Net scientists could not pass through a particular source of high energy neutrino. The researchers probably scanned the small patch of heaven, but they did not see the smoking gun Active galactic nucleus It is called blazar, who scientists expect the immediate suspect Shenanigans of heaven. This can be said that it can be neutrinum, coming from a cosmic cosmic cosmic ray taken by a photon taken from the background light or Cosmic microwave BackgroundResearchers discuss.
“This event is curious; I think that’s very good.”
Esoteric choices are disturbing astrefysical neutrinos, but scientists first examine. Most astronomical observations remain focused on photons, but the photons can be easily blocked. In contrast, the ghost nature of neutrin means traveling in a straight line in a straight line, offering another lens in the universe that looks back His first days. With light, “It seems to be how much it is,” Ramson said, that is, the photonic fog of cosmic microwave, after 380,000 years after the Big Bang. “Neutrinos is a way to drill this veil and you can look back more than ever.”
Whether scientists are on the verge of drilling this veil, whether Km3net continues to make amazing observations like 2023 detection, whether Icecube can join so long without observation of so high energy particles. Right now, the discordioy discord in the vision of detectors is confusing, to say the least. “They were lucky enough; it’s hard to tell,” says Scholberg. “It’s very fascinating, and it clearly means that we need more data.”
Taboada is allowed to tip the perception manually, but neutrino scientists need more observations to learn to interpret KM3Net’s catch. “If the astrophysic neutrino proved, that would be monumental,” says Taboada. But he wants to see more. “This event is curious; I think that’s good to carry,” he said. “It’s unexpected, when you look more.”
