About this profile
An unnormalized intensity, amplitude, or theory-response model. Normalization or an observation model is supplied separately.
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.
COMPASS · \(\pi p\to3\pi p\) partial waves ¶
Public complex amplitudes and covariance matrices provide inputs for a reduced resonance-model reconstruction of \(\pi p\to3\pi p\).
Reproduction status
Scoped. Independent validation pending. Status updated 2026-07-17.
Statistical model ¶
This case concerns closed-form amplitude. Resonance-model curves on published wave intensities and phases for a reduced wave subset
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.
- Beam and target process
- mass and momentum-transfer bins
- partial waves, reflectivity and spin conventions
- isobar parameterizations and rank assumptions
- acceptance corrections, spin-density matrices and systematic wave-set variations.
Reproduction objective and evidence ¶
Objective: Resonance-model curves on published wave intensities and phases for a reduced wave subset
Scope and limitations: The reduced forward-model reproduction is still to be built.
Figures ¶
Reference figures from the publication cited below, showing an example of the intensity- and \(t'\)-distributions of the \(0^{-+}\) partial wave.
