West versus East

  1. Jan 23, 2009 #1
    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)?
