The measurements of off-shell Higgs boson contributions in massive gauge boson pair production are known to probe its electroweak interactions across different energy scales. Often employed as an estimator of the Higgs boson width in restricted theories of beyond the Standard Model physics, we revisit this measurement and readvertise its potential to constrain aspects of Higgs boson nonlinearity. We show that this so-called off-shell measurement complements related analyses of multi-Higgs final states.
