Diffractive Eta_c Photo- and Electroproduction Cross Sections

A physics dataset containing calculated cross sections for diffractive eta_c meson production via photon and electron interactions. The data was generated by researchers at Universität Hamburg using a new set of odderon states, finding an enhancement of about one order of magnitude compared to previous three-gluon exchange models. The cross section's t-dependence exhibits a dip structure in the small t region.

Use Cases

• Modeling diffractive cross sections based on odderon state calculations.
• Comparing theoretical predictions for eta_c production based on photon and electron interactions.
• Analyzing the t-dependence of cross sections for dip structure features.

Strengths

• Results are based on a new set of odderon states, providing a theoretical advancement.
• Calculations show an enhancement of about one order of magnitude in the cross section compared to prior models.
• The t-dependence analysis reveals a specific dip structure in the small t region.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
