Phenomenological Implications of the $p_T$ Spectra of $\varphi$ and $\Omega$ produced at LHC and RHIC

Abstract

The data on the $p_T$ spectra of $\varphi$ and $\Omega$ at LHC can be presented in a format that shows exponential behavior up to $p_T\approx 6$ GeV/c with the same slope for both particles and for nearly all centralities. They are empirical properties that are shared at lower energies with the inverse slope showing a power-law dependence on $\sqrt{s_{NN}}$. The shared properties of the spectra are shown to emerge naturally from the recombination model. No flow is needed. We find experimental hints for the possibility that $\varphi$ and $\Omega$ are mostly produced in the ridge that are generated by minijets. Appropriate experimental test is suggested.
