What is recorded here?
Clasie and collaborators measured pion electroproduction on deuterium, carbon, aluminium, copper and gold targets over momentum transfers squared of approximately 1.1–4.7 (GeV/c)². Their extracted nuclear transparency and its target-mass dependence varied with momentum transfer, in better agreement with the specific calculations incorporating color transparency than with the displayed conventional calculations.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
Transparency is a model-dependent super-ratio involving a simulated reference without pion–nucleon final-state interactions, not a direct image of a small pion. Observations support the stated model comparison, not a unique proof of color transparency or QCD factorization. Model and point-to-point uncertainties are separate, the compared models share parameters, and the authors called for higher-momentum data. The individual contributor list shown here is incomplete. Figure 2 labels aluminium as 29Al while the text identifies 27Al; preserve the original discrepancy pending verification.
