On Monday, July 17, 2006, Sabine Hossenfelder writes in her blog about "Neutrinos for Beginners".

The author writes, "Neutrinos come in three flavours."

She adds, "Each of them belongs to a charged fermion."

The writer of the "Neutrinos for Beginners" addresses:

"There is the electron, the muon and the tau-neutrino."

The author explains, "Neutrinos are produced in interactions (e.g. in the sun) and start their travel with one of these flavours."

The writer of the information points out, "However, while time goes by,they can change from one flavor to another, and back, in a periodic process."

"Which flavor you find then depends on the time that passed after the neutrino was produced - or the distance it travelled during this time, respectively "

On 7 Oct 2019, the Physical World's website "physicalworld.com" paid attention about the neutrino mass.

Hence, the neutrino mass became an interesting subect. The Physical World's website published "My favourite Nobel prize: weighing up neutrino mass" written by Tushna Commissariat.

The author writes:

While neutrino science has significantly advanced in the years since both those experiments, there are still many questions, including the fact that we still don’t know what the exact masses of the three neutrino flavours, or how they achieve this mass."

The writer adds:

"I’ve always been fascinated by neutrinos, those tricksy fundamental particles that abound the universe ( you’ve probably heard it before, but some 65 billion neutrinos pass through a space as small as your fingernail every second) but are rather hard to detect, as they are electrically neutral, and only interact with matter via gravity and the weak force."

She continues:

The day after the 2015 prize, I wrote a blog about why improving our understanding of neutrino mass is so important, when it comes to some of the big unanswered question in physics today."

The author goes on to address:

"First predicted 89 years ago by Wolfgang Pauli as a “desperate remedy” for discrepancies arising in the study of beta decays, these so-called ghostly particles were thought to be impossible to detect."

On 9 Sep 1999, the Scientific American "scientificamerican.com" published an article entitled "What is neutino" written by Aksel L. Hallin, a physics professor at Queen's University and the Sudbury Neutrino Observatory.

In one part of his 1999 article in the magazine the author explains:

"While neutrino science has significantly advanced in the years since both those experiments, there are still many questions, including the fact that we still don’t know what the exact masses of the three neutrino flavours, or how they achieve this mass."

On April 15, 2020 the Quant Magazine "quantmagazine.com" publushed an article entitled "Neutrino Asymmetry Passes Critical Threshold" written by Natalie Wolchover.

The author writes:

"Neutrinos are omnipresent but mysterious, easy to create but hard to catch."

The writer adds:

"They spew from nuclear reactions in the sun and stars and stream through our bodies by the trillions each second."

Natalie Wolchover (the author) addresses:

"The super lightweight particles are so elusive that their properties are still being explored."

The writer explains:

"Experiments since the 1990s show that, as neutrinos and antineutrinos fly along, they change between three types, or “flavors,” labeled electron, muon and tau."

The author points out:

"Since 2010, the T2K scientists have been generating muon-flavored neutrinos and antineutrinos in Tokai, Japan, and beaming them 295 kilometers to Kamioka — the location of the Super-Kamiokande neutrino observatory, an underground, sensor-lined tank of 50,000 metric tons of pure water."

The writer continues to address:

"Given this, and the fact that neutrinos have an inexplicably tiny amount of mass, experts suspect that neutrinos and antineutrinos once had super heavy counterparts with opposite handedness — right-handed neutrinos and left-handed antineutrinos."

The Science Alert "sciencealert.com" has a title for its informstion about neutrino:"What Are Neutrinos?"

This website intorms:

"Neutrinos are a type of particle similar to the electron, and belong to lepton family of fundamental particles."

The information in the website says:

"Neutrinos are distinguished by a lack of charge and a mass that's virtually non-existent."

"Emitted as a part of the beta decay process that turns neutrons into protons, neutrinos are one of the most abundant of subatomic particles in the Universe, with tens of billions hitting your fingernail every second."

On Sept 17, 2019 Forbes magazine "forbes.com" published an article entitled "This Is Why Neutrinos Are The Standard Model's Greatest Puzzle" written by Ethan Siegel, a senior contributor to the magazine.

The author writes:

"Neutrinos, like electrons, are also leptons."

The writer adds, "Although they don’t have electric charge, they do have quantum numbers all their own."

He addresses, "Just as an electron has an antimatter counterpart (the positron), the neutrino has an antimatter counterpart as well: the antineutrino."

The author writes, "Although they were first theorized in 1930 by Wolfgang Pauli, the first neutrino detection didn’t take place until the mid-1950s, and actually involved antineutrinos produced by nuclear reactors."
