I hear the phrase vector mass being used a lot in discussions of various models in particle physics.
But I am not exactly sure what it means.
There is no Wikipedia article on this term. Is vector mass somehow different from scalar mass?
The only possible mass terms in the Lagrangian arise due to quadratic self-interactions and interactions between different fields. In this respect, we have a scalar mass and a mass matrix respectively.
