Analysis demonstrates effects of unparticle and axion-like particles on Bhabha scattering cross-section, suggesting new physics insights.
The effect of the unparticle and axion-like particle (ALP) at Bhabha scattering is analyzed. We evaluate the total cross-section with the propagators of gauge boson \(γ, Z\), unparticle (scalar and vector unparticle), and ALP which depends on the model parameters. Moreover, the comparison between scalar, vector unparticle contribution and ALP contribution is evaluated. The benchmark signal point of \((d_U,Λ_U)\) in the Bhabha scattering is shown as \((d_U,Λ_U) = (1.1,1\,\,{TeV})\).
