Unparticle effects on Dark Matter production from photon and axion-like
Abstract
In this work, we study the effects of vector unparticle on the \(a\gamma \to \chi \bar{\chi}\) process, where \(\chi\) is a dark matter fermion. Our numerical results show that the cross-section takes values from \(8.23 \times 10^{-15}\,\text{barn}\) to \(5.12 \times 10^{-14}\,\text{barn}\). Consequently, the cross-section with unparticle effect should be about \(10^{26}\text{--}10^{28}\) times larger that obtained via pure photon exchange. This enhancement could be important for searching for dark matter, as well as unparticle.
