An Unstable Particle Produced in a High-Energy Collision Is Measured

question 5

Short Answer

An unstable particle produced in a high-energy collision is measured to have an energy of 483 MeV and an uncertainty in energy of 84 keV.Use the Heisenberg uncertainty principle to estimate the lifetime of this particle.( h = 1.055 × 10^-34 J • s = 6.59 × 10^-16 eV • s)

Definitions:

Null Hypothesis

A hypothesis that there is no significant difference between specified populations, any observed difference being due to sampling or experimental error.

Null Hypothesis

In statistical testing, it is the default assumption that there is no difference or effect, intended to be either rejected or not rejected based on data.

Type II Error

The error that occurs when a false null hypothesis is not rejected, also known as a false negative.
