Unparticle effects on plasmon production from electron-positron annihilation in SN 1987A

Key Points

Plasmon production is influenced by unparticle effects with varying cross-section values across energy ranges.
The calculated cross-section varies from 4.663×10−20 barn to 6.206×10−3 barn, impacting experimental detection.
Assuming a cooling rate of ≤ 7.288×10−27 GeV, we estimate lower bounds on the unparticle scale of 2.770 to 32.849 TeV.
Experimental signatures for unparticle effects may offer new insights into astrophysical processes within supernovae.

Abstract

The unparticle effects on plasmon production at the e+ e− collider in SN 1987A are investigated. We have calculated the energy loss and the cross-section of this process for different values of the scaling parameter dU. By assuming the supernovae cooling rate ≤ 7.288×10−27 GeV, we find the lower bound on the scale ΛU = 32.849 TeV, 11.655 TeV, 5.084 TeV, 2.770 TeV corresponding to dU =1.6,1.7,1.8,1.9 and ΛU = 0.675 TeV, 0.309 TeV, 0.168 TeV, 0.101 TeV corresponding to dU = 2.1,2.2,2.3,2.4. In addition, we have shown that in the range =1 TeV – 13 TeV the cross-section varies from 4.663×10−20 barn to 6.206×10−3 barn. So, we hope that the cross-section gives possible experimental signatures for unparticle.
