On connection of the cosmic-ray coplanarity of most energetic particles with the collider long-range near-side "ridge" effect

TL;DR

This paper links the coplanarity observed in cosmic-ray particles with the collider's near-side 'ridge' effect, suggesting a common underlying mechanism, and demonstrates that the FANSY 2.0 model can reproduce both phenomena.

Contribution

It introduces the FANSY 2.0 model that successfully reproduces cosmic-ray coplanarity and the collider's 'ridge' effect, proposing a unified explanation for both phenomena.

Findings

FANSY 2.0 model reproduces cosmic-ray coplanarity.

FANSY 2.0 model reproduces the 'ridge' effect in collider data.

Unified explanation for cosmic-ray and collider phenomena.

Abstract

Coplanarity of subcores of $\gamma$-ray--hadron families found in cosmic-ray experiments at $E_0 \gtrsim 10^{16}$ eV requires appearance of a coplanar generation of most energetic particles. Long-range near-side "ridge" effect in $ pp$ collisions at $\sqrt{s} = 7$ TeV was found by the CMS Collaboration in two-particle $\Delta\eta - \Delta\varphi$ correlation functions at $|\Delta\eta| \gtrsim 3$ and $|\Delta\varphi| \approx 0$. The FANSY 2.0 model reproduces both the hadron coplanarity and "ridge" effect.
