'Ghost Particles': Scientists Finally Detect Neutrinos in Particle Collider


Love that image BTW :-).

Abstract impression of a particle collider.


"For the first time, scientists have detected neutrinos created in a particle collider."

"Those abundant yet enigmatic subatomic particles are so removed from the rest of matter that they slide through it like specters, earning them the nickname "ghost particles".


"The researchers say this work represents the first direct observation of collider neutrinos and will help us to understand how these particles form, what their properties are, and their role in the evolution of the Universe."


"We've discovered neutrinos from a brand-new source – particle colliders – where you have two beams of particles smash together at extremely high energy," says particle physicist Jonathan Feng of the University of California Irvine.


"Neutrinos are among the most abundant subatomic particles in the Universe, second only to photons. But they have no electric charge, their mass is almost zero, and they barely interact with other particles they encounter. Hundreds of billions of neutrinos are streaming through your body right now."

(We exist is something that we only have the ability to experience 3-4% of somebody keeps saying :-)


"The particle tracks produced by a candidate event consistent with the production of an electron neutrino. (Peterson et al.)"

(I just like the pictures :-).


"Neutrinos are produced in energetic circumstances, such as the nuclear fusion that takes place inside stars, or supernova explosions. And while we may not notice them on a day-to-day basis, physicists believe that their mass – however slight – probably affects the Universe's gravity (although neutrinos have pretty much been ruled out as dark matter)."


"Although their interaction with matter is small, it's not completely nonexistent; now and again, a cosmic neutrino collides with another particle, producing a very faint burst of light."

"Underground detectors, isolated from other sources of radiation, can detect these bursts. IceCube in Antarctica, Super-Kamiokande in Japan, and MiniBooNE at Fermilab in Illinois are three such detectors."


"Neutrinos produced in particle colliders, however, have long been sought by physicists because the high energies involved are not as well studied as low-energy neutrinos."


"They can tell us about deep space in ways we can't learn otherwise," says particle physicist Jamie Boyd of CERN."


"Now, the researchers have confirmed their discovery, using data from the third run of the upgraded LHC that began last year, with a significance level of 16 sigma."

"That means that the likelihood that the signals were produced by random chance is so low as to be almost nothing; a significance level of 5 sigma is sufficient to qualify as a discovery in particle physics."


"Back in 2021, physicist David Casper of UC Irvine projected that the run would produce around 10,000 neutrino interactions, which means we've barely scratched the surface of what FASERnu has to offer.

"Neutrinos are the only known particles that the much larger experiments at the Large Hadron Collider are unable to directly detect," he says, "so FASER's successful observation means the collider's full physics potential is finally being exploited."


Colossians 1:16-17 

For by Him all things were created that are in heaven and that are on earth, visible and invisible, whether thrones or dominions or principalities or powers. All things were created through Him and for Him. And He is before all things, and in Him all things consist.



Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.


Etc...:-).
