Proper Mass redux

[juanrga]

Only to people who don't know what the term proper means. In this context the term proper means intrinsic.

 

Terminology has to be systematic and unambiguous and "proper mass" is rather inadequate. The intrinsic properties of a quantum particle are mass, spin, and charge. There is no need to add labels to "mass".

 

"we" is what is found in the literature and "we" understand and use the term proper mass or rest mass too when that is the subject

 

A simple search in the literature reveals that the terms "proper mass", "invariant mass", and "mass" are used in proportions of about 1:10:1000.
