Constraints on LV in QED at on a log-log plot. For negative parameters minus
the logarithm of the absolute value is plotted, and region of width is excised around each
axis. The constraints in solid lines apply to and both , and are symmetric about both the
and the axis. At least one of the two pairs must lie within the union of the dashed
bell-shaped region and its reflection about the axis. Intersecting lines are truncated where they
cross. |
