Mass generation

In theoretical physics, a mass generation mechanism is a theory that describes the origin of mass from the most fundamental laws of physics. Physicists have proposed a number of models that advocate different views of the origin of mass. The problem is complicated because mass is strongly connected to gravitational interaction, and no theory of gravitational interaction reconciles with the currently popular Standard Model of particle physics.

There are two types of mass generation models: gravity-free models and models that involve gravity.

In these theories, as in the Standard Model itself, the gravitational interaction either is not involved or does not play a crucial role.
