What is the total decay rate of N(1875) from the particle data group?

In summary, the conversation discusses the decay branching ratios of N(1875) and the difficulty in determining the total width due to inconsistencies in the "Breit Wigner width." The solution is found in the references at the end of the PDG section on that particle, where the researchers explain their methods. The conflicting widths and branching fractions are a result of multiple broad resonances overlapping, making it challenging to accurately assign events. Further details can be found in the references.

From particle data group,(http://pdg.lbl.gov/2014/listings/contents_listings.html)
I can see the decay branching ratios of N(1875),but the total width is not found.The "Breit Wigner width " are very different.So my question is ,How do they get the branching ratio without a certain total width?

You see all those references at the end of the PDG section on that particle? That's where the people who did the work explain how they did it.

Which means the width is poorly known, and also the branching fractions are inconsistent. As you have many broad resonances overlapping, it is hard to assign events to specific resonances. See the references for details.

1. What is the definition of total decay rate of N(1875)?

The total decay rate of N(1875) refers to the rate at which all possible decay modes of the N(1875) nucleus occur, including both radioactive decay and other types of decay such as fission or spontaneous emission of particles.

2. How is the total decay rate of N(1875) measured?

The total decay rate of N(1875) can be measured by counting the number of decays that occur in a given amount of time and dividing by the initial number of N(1875) nuclei. This can be done using various detection methods such as a Geiger counter or a particle accelerator.

3. What factors affect the total decay rate of N(1875)?

The total decay rate of N(1875) can be affected by various factors such as the type of nucleus, its energy level, and its surrounding environment. Additionally, factors such as temperature and pressure can also impact the decay rate of N(1875).

4. Is the total decay rate of N(1875) constant?

No, the total decay rate of N(1875) is not constant. It can vary depending on the conditions mentioned above, and it can also change over time due to natural processes such as radioactive decay and nuclear reactions.

5. How does the total decay rate of N(1875) relate to its half-life?

The total decay rate of N(1875) is directly related to its half-life. The half-life is the time it takes for half of the initial number of N(1875) nuclei to decay, and the total decay rate is the inverse of this time. Therefore, the higher the total decay rate, the shorter the half-life of N(1875) will be.
