Is the Single Proton Really Stable? Exploring Theories of Particle Decay

In summary, the single proton life time is the amount of time that a single proton can exist before decaying into smaller particles. It is important in particle physics and is currently estimated to be around 10^34 years. It affects our understanding of the universe and can have implications for the stability of matter. The single proton life time is measured through experiments using particle accelerators and detectors, but it is still a topic of ongoing research and debate. If the life time is found to be shorter or longer than currently estimated, it could have significant implications for our understanding of the fundamental forces and particles that make up the universe.

We know hydrogen atom is stable. Then, single proton is stable? Can we store it for a long time without decay?
Do we have any related equation about particle stability?

It is currently unknown whether a proton is stable or not. We have never observed one to decay, but it could be either case.

In the standard model the proton is stable, but there are various GUT proposals which predict proton decay. Simple models like SU(5) and SO(10) have been ruled out experimentally b/c of the measured minimum proton lifetime; other's are still allowed.
 

What is the single proton life time?

The single proton life time refers to the amount of time that a single proton, the basic building block of atoms, can exist before decaying into smaller particles. It is an important concept in particle physics and is currently estimated to be around 10^34 years.

Why is the single proton life time important?

The single proton life time is important because it affects our understanding of the fundamental forces and particles that make up the universe. It also has implications for the stability of matter and the potential for proton decay, which could have significant consequences for the future of the universe.

How is the single proton life time measured?

The single proton life time is measured through experiments using particle accelerators and detectors. Scientists study the decay products of protons to determine their average lifetime. This process requires precise measurements and can also be affected by theoretical models and assumptions.

Has the single proton life time been accurately determined?

The single proton life time is currently estimated to be around 10^34 years, but this number is not set in stone. It is a topic of ongoing research and debate in the scientific community. As our understanding of particle physics improves and technology advances, we may be able to refine our measurements and theories about the single proton life time.

What are the implications of a shorter or longer single proton life time?

If the single proton life time is found to be shorter than currently estimated, it could have major implications for our understanding of the universe and the stability of matter. On the other hand, if it is found to be longer, it could lead to new theories about the fundamental forces and particles that govern our world.
