If a Σ^- Particle at Rest Decays into a Neutron

question 26

Short Answer

If a Σ^- particle at rest decays into a neutron and a π^- , what is the total kinetic energy of the decay products? The masses of Σ^-, neutron, and π^- are 1197 MeV/c², 940 MeV/c², and 140 MeV/c², respectively.

Definitions:

Interval Data

Interval data refers to a type of quantitative data that not only categorizes and orders the quantities but also precisely measures the differences between them. Unlike ordinal data, interval data has equal intervals between values, making mathematical operations meaningful.

Ratio Data

A type of quantitative data that possesses a natural zero point and allows for meaningful comparisons using division, enabling measurement of both differences and ratios between data points.

Variance

Variance is a statistical measure that represents the degree to which a set of observations differ from each other. It is the expectation of the squared deviation of a random variable from its mean, and it gives insights into the dispersion of a dataset.

Standard Deviation

A measure of the amount of variation or dispersion of a set of values.
