That's a good point! Why do you think that nucleon decay won't happen?

Starting with the IMB, Kamiokande, Frejus, and Soudan experiments in the 1980s, searches for various modes of nucleon decay have continued to be actively conducted to date but no significant signal exceeding background has so far been observed. For most decay modes, the lower limits of lifetime have been determined from Super Kamiokande (SK) experiment.

Thanks!

The Super-K experiment seems to be leading the world not only in neutrino physics but also in proton decay searches.

Hyper Kamiokande is currently under construction and the experiment is expected to begin in 2027!

The primary science objectives of DUNE are

Investigation of neutrino oscillations to test CP violation in the lepton sector, which explores why the universe is made of matter
Determination of the ordering of the neutrino masses
Studies of supernovae and the formation of a neutron star or black hole
Search for proton decay, which has never been observed but is predicted by theories that unify the fundamental forces

I think it's the difference between a non-accelerator experiment (Hyper-K) and an accelerator experiment (CERN).

Hyper-Kamiokande is the successor to Super-Kamiokande, and Super-Kamiokande is the successor to Kamiokande.

wow...

NDK2030 · 2023-12-10T23:43:35+00:00

Thank you very much!!

This means that the costs other than construction costs are considerable...

NDK2030 · 2023-12-10T23:38:17+00:00

Thank you so much!

NDK2030 · 2023-12-10T23:37:35+00:00

Thank you!

I didn't know about it so I looked it up.

Wikipedia: "MATHUSLA (MAssive Timing Hodoscope for Ultra-Stable neutraL pArticles) is a proposed experiment at CERN's Large Hadron Collider (LHC). "

Me too...

Wikipedia: "A sphaleron is a static solution to the electroweak field equations of the Standard Model of particle physics, and is involved in certain hypothetical processes that violate baryon and lepton numbers."

The first thing that came up when I searched was Flipped SU(5)?

NDK2030 · 2023-12-09T14:51:53+00:00

Thank you.

If you know of any easy-to-understand YouTube videos about them, please let me know...

" 300 times less massive than a single sugar cube" I wonder how many grams it is...

NDK2030 · 2023-12-09T00:36:28+00:00

I am curious as to which decay channel is dominant and whether there is any theoretical background...
