The Depth of the Higgs Potential: A Measured Contribution Fifty-Five Orders Larger Than the Vacuum Density Observed

The Higgs potential at its minimum is a vacuum energy density computed entirely from measured quantities: a vacuum expectation value of 246.22 GeV and a Higgs mass of 125.25 GeV. This paper evaluates the depth in two algebraically equivalent forms, which agree to a relative difference of 0, obtaining -1.19 x 10^8 GeV^4. Its magnitude exceeds the observed vacuum density of 2.52 x 10^-47 GeV^4 by a factor of 4.72 x 10^54, so other contributions must cancel it to 54.7 decimal digits and leave a small positive remainder. Unlike cutoff estimates, this contribution involves no untested scale. The paper is a computation from stated inputs, not a measurement.
