Analysis profile

Flavor anomalies

Belle II · \(B^0\to K^{*0}\tau^+\tau^-\)

Forward model (pdf)

The released pyhf workspace defines a binned probability model. Toy experiments calibrate limits rather than define the forward prediction.

Forward 0.1 core-h
Params 100
Analysis 10 core-h
Input 1 MB
Tools 2
Code 5000 LOC
Cites 10

Approximate analysis-scale values; costs depend on the workload and implementation.

About this profile

An explicit probability model or likelihood, including count probabilities. Monte Carlo may have been used to prepare templates or calibrate tests.

Metrics describe the scoped analysis and are approximate unless explicitly measured. Colored squares show metric-specific size bands; they are not scores. “Cites” is a reference-count estimate, not a live citation count.

Belle II · \(B^0\to K^{*0}\tau^+\tau^-\) ¶

Use the released binned likelihood to investigate an upper limit on the \(B^0\to K^{*0}\tau^+\tau^-\) branching fraction.

Reproduction status

In progress. Independent validation pending. Status updated 2026-07-17.

Statistical model ¶

This case concerns bin lookup. Observed/expected 90% CL upper limit on the branching fraction from the released pyhf workspace

The reproduction objective below defines the current scope; a complete published-analysis reproduction is not asserted.

Model ingredients ¶

Reusing this model requires the ingredients below. Availability and limitations are described in the reproduction evidence.

  • Hadronic-tagging categories and τ decay modes
  • classifier-output bins
  • signal and background templates
  • nuisance parameters and the profile-likelihood limit-setting procedure.

Reproduction objective and evidence ¶

Objective: Observed/expected 90% CL upper limit on the branching fraction from the released pyhf workspace

Scope and limitations: Preliminary numerical fits use the released pyhf likelihood. A completed likelihood scan and validated limit reproduction are not yet available.

Public release ¶

A released pyhf likelihood on HEPData.
