What is 'bare mass' in context with particle physics?

06 June 2017 1 2K Report

As we know, the observed mass of a particle is the sum of the bare mass and the quantum corrections. Physically, how can I understand bare mass? Is it the mass at the tree level?

Why the anti-commutation of gamma matrices give a flat metric?

We know that ${\gamma_{mu},\gamma_{nu}}$= 2 $g_{\mu\nu}$, where $g_{\mu\nu}$ is the flat metric . That shows spinors are someway related to the metric of space. Can anyone please explain how?
