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

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 $\mathrm{\Delta }\eta -\mathrm{\Delta }\phi$ correlation functions at $\mathrm{\mid }\mathrm{\Delta }\eta \mathrm{\mid }\gtrsim 3$ and $\mathrm{\mid }\mathrm{\Delta }\phi \mathrm{\mid }\approx 0$. The FANSY 2.0 model reproduces both the hadron coplanarity and “ridge” effect.
