The mass of a particle is defined as
![\[mc^2=\sqrt{E^2-p^2 c^2}\]](https://belle2.ijs.si/public/wp-content/ql-cache/quicklatex.com-8966d0dde1e612d7e3cb7b9404713187_l3.png "Rendered by QuickLaTeX.com")
In the application, the mass is calculated automatically.
In this exercise
- Plot the distribution of particles according to their mass
- Change particle identity and see how the distribution changes in the following ranges:
- From 0 to 3
- From 0 to 0.0005
- From 0 to 3
Use the following blocks
