Predicted Since 1960, This Natural Phenomenon Has Finally Become A Reality

JAKARTA – predicted since 1960, finally the most distant particle detector at Earth has detected antimatter particles most energetic ever. Namely, one ultralight particle that hit the ice Antartika with the roar of the energy of 6,300 mosquitoes that were flying. Also read: Ancient Magma Ocean Traces Found Scattered in Greenland

The collision occurred in 2016, but the researchers only confirmed the details of the March 10 event in a paper published in the journal Nature. This antineutrino, call Live Science, The antimatter pair of hard-to-detect thin particles, known as neutrinos, collide with an electron somewhere in the Antarctic ice at nearly the speed of light.

The collision created a rain of particles detected by the IceCube Neutrino Observatory – the facility responsible for most of the important high-energy neutrino research in the last decade. Now, IceCube physicists are reporting that the particle rain includes evidence of a long-theorized but never-before-seen event known as “Light Resonance”.

Back in 1960, physicist Stephen Glashow, then a graduate researcher at the Nordic Institute of Theoretical Physics in Denmark, predicted that when an antineutrino of high enough energy collides with an electron, it will produce a heavy, short-lived particle known as a W boson. Glashow’s predictions rely on the ground rules of the Standard Model of particle physics, a theory that dominates the way researchers understand everything from the interior of the atom to light to antimatter.

Detecting Glashow resonance is strong confirmation of the Standard Model. But it takes neutrinos to carry far more energy than the particle accelerators of the 1960s could produce.

It is usually difficult to make a sense with the numbers involved in high-energy particles. A neutrino has a mass of about 2 billion-billion-billion-billion grams, and thousands of low-energy neutrinos from the Sun pass through your body every second of the day with no visible effect. Neutrinos with an energy of 6.3 mapelectronvolts (PeV) are another “beast.”

According to CERN, the European physics laboratory, a teraelectronvolt (TeV) is equivalent to the energy of a mosquito flying at a speed of 1 mph (1.6 km / h). And 6.3 PeV is 6,300 TeV. So turn that one mosquito into a swarm of 6,300 (or accelerate to Mach-8.2, more than four times the top speed of the F-16) and you get the energy from a single, minuscule particle needed for Glashow resonance.

Another way to think about 6.3 PeV: This is 450 times the maximum energy that the Large Hadron Collider – the 17 mile (27 kilometers) long, multibillion-dollar CERN accelerator responsible for detecting the Higgs boson – should be able to produce by the end of 2020- and keep up with the ongoing upgrades.

Given the enormous energy it required, no one expected to see Glashow resonance using only human tools. But the IceCube, which detects particles falling from the sky, has some help from the universe. The particles that hit the ice in 2016 produced the characteristic rain of particles that researchers now think came from the W boson, which are the fundamental particles that together with the Z boson are thought to be responsible for the weak force. And that’s a sign of 6.3-PeV antineutrino and Glashow resonance.

Researchers are still not sure what cosmic accelerator produced a dreadful speck of antimatter. But say more events will help them fine-tune their model of whatever natural space canon generates extreme particles and shoots them toward Earth.
