Does anyone know of an authoritative online source which gives a complete table of particle lifetimes?

Thanks

1. What is a Table of Particle Lifetimes?

A Table of Particle Lifetimes is a chart or list that displays the average lifespan of various subatomic particles, which are the building blocks of matter. It is an important tool in particle physics and helps scientists understand the fundamental properties of matter.

2. What types of particles are included in a Table of Particle Lifetimes?

The table typically includes both subatomic particles found in nature, such as protons and electrons, as well as particles created in high-energy particle collisions, such as quarks and neutrinos. There are also unstable particles that decay quickly, such as muons and tau particles.

3. How are particle lifetimes measured and recorded?

Particle lifetimes are measured using sophisticated equipment, such as particle accelerators, and are recorded in units of time called nanoseconds (ns) or picoseconds (ps). This is because particles have extremely short lifespans, ranging from fractions of a second to less than a trillionth of a second.

4. Why is a Table of Particle Lifetimes important in physics research?

Particle lifetimes provide valuable information about the behavior and interactions of particles, which can help scientists understand the fundamental laws of the universe. By studying the lifetimes of particles, physicists can also make predictions about the stability and decay of matter.

5. Are there any limitations to the accuracy of a Table of Particle Lifetimes?

Yes, there are limitations to the accuracy of a Table of Particle Lifetimes. Since particles decay at different rates depending on their energy and environment, the lifetimes listed in the table are average values. Furthermore, new particles are constantly being discovered and studied, so the table may not always include the most up-to-date information.
