SUMMARY

The discussion confirms that converting results between the West Coast metric (1,-1,-1,-1) and the East Coast metric (-1,1,1,1) is achievable by swapping the signs of all scalar quantities. This includes the metric tensor, Lagrangian, scalar fields, vector fields, and phases. Furthermore, gamma matrices and spinor fields must also be replaced with their negative counterparts to maintain consistency in the transformation. This conversion is essential for ensuring accurate calculations in theoretical physics.

PREREQUISITES
  • Understanding of metric tensors in theoretical physics
  • Familiarity with Lagrangian mechanics
  • Knowledge of scalar and vector fields
  • Basic concepts of gamma matrices and spinor fields
NEXT STEPS

Is there a way to convert results from the West Coast metric (1,-1,-1,-1) to the East Coast metric (-1,1,1,1) or vice versa (is this terminology U.S.-centric?)?

Since [tex]p_{\mu}p^{\mu}=\pm m^2[/tex], does this mean you can just replace a scalar like m^2 with -m^2, or add a negative sign to every contraction instead?

Does the Lagrangian, which is an invariant scalar, get replaced with a negative sign? What about scalar fields? Do they change sign? Spinor fields and gamma matrices? Vector fields? Phases (exponential of a contraction)?

Yes, it is possible to convert from the West Coast metric to the East Coast metric (or vice versa) by swapping the sign of all scalar quantities such as the metric tensor, Lagrangian, scalar fields, vector fields, and phases. Additionally, the gamma matrices and spinor fields must be replaced with their negative counterparts.
