How to estimate the upper limit mass of electron neutrino?

In summary, the upper limit mass of electron neutrino is estimated through a combination of experimental measurements and theoretical calculations. The current estimated upper limit mass is less than 1 eV and is significantly lower than the upper limit mass of other neutrino types. It cannot be measured directly and is important for understanding the fundamental properties of these particles and their implications in various fields of physics.

If I just know the energy range of it is 10-35 MeV, and they can interact with detector for 10 seconds, how to deduce the upper limit mass of it?

As I understand it they measure the maximum energetic electron from the beta decay of tritium. The missing energy from the mass difference of H3 minus He3 minus the most energetic electron produced is an upper limit on the rest mass of an electron neutrino.
 

1. How is the upper limit mass of electron neutrino estimated?

The upper limit mass of electron neutrino is estimated through a combination of experimental measurements and theoretical calculations. Scientists use data from experiments such as beta decay and neutrino oscillation to determine the mass of other types of neutrinos, which can then be used to estimate the upper limit for the mass of electron neutrinos.

2. What is the current estimated upper limit mass of electron neutrino?

The current estimated upper limit mass of electron neutrino is less than 1 eV (electron volt). This value is based on the most recent experimental and theoretical data, but it is still considered an open question in the field of particle physics.

3. How does the upper limit mass of electron neutrino compare to other neutrino types?

The upper limit mass of electron neutrino is significantly lower than the upper limit mass of other neutrino types, such as muon and tau neutrinos. This is due to the fact that electron neutrinos have the lightest mass among all three types of neutrinos, according to current scientific understanding.

4. Can the upper limit mass of electron neutrino be measured directly?

No, the upper limit mass of electron neutrino cannot be measured directly. Neutrinos are notoriously difficult to detect and their masses are extremely small, making direct measurement nearly impossible. Instead, scientists rely on indirect methods to estimate the upper limit mass of electron neutrino.

5. Why is it important to estimate the upper limit mass of electron neutrino?

Estimating the upper limit mass of electron neutrino is important for understanding the fundamental properties of these elusive particles. It can also provide insights into the structure of the universe and the behavior of matter and energy at the smallest scales. Additionally, it has implications for other areas of physics, such as cosmology and particle physics.
