Conjecture on ESS intercept’s dependence on event content

Characterize and validate the conjectured functional dependence of the Event-Shape Selection (ESS) intercept ΔγESS on the full event content, including resonance abundances relative to primordial pions, resonance elliptic anisotropies and transverse-momentum spectra, and primordial particle elliptic anisotropies and transverse-momentum spectra.

Background

The authors propose, based on toy-model and physics-model simulations, that the ESS intercept ΔγESS is not solely a CME measure but is shaped by a complex interplay of event elements. Variations in resonance content or mass continuum significantly alter ΔγESS, indicating an intricate dependence that is not yet quantified.

This conjecture motivates a need for a systematic characterization of how ΔγESS varies with event composition to assess the reliability of ESS-based CME searches.

References

We conjecture that the ESS intercept $\dgess$ is a complicated function of all elements making up the event.
