Public likelihood for B→K νν̄

The official Belle II collaboration paper releasing a public, model-agnostic likelihood for the \(B^+\to K^+\nu\bar\nu\) measurement, built with the general method described above. It lets anyone test their own new-physics model against the measurement's data directly, without access to the internal analysis.

Published as: Model-agnostic likelihood for the reinterpretation of the \(B^+\to K^+\nu\bar\nu\) measurement at Belle II, Phys. Rev. D 112, 092016 (2025).

Posterior constraints on the effective Wilson coefficients of a general \(b\to s\nu\bar\nu\) contact interaction, from the public likelihood applied to the full \(B^+\to K^+\nu\bar\nu\) measurement.

Try your own reinterpretation — a minimal worked example, from loading the public likelihood to a full WET fit.
