Dilepton Production from Dropping rho in the Vector Manifestation

TL;DR

This paper analyzes how the dropping rho meson affects thermal dilepton production rates, highlighting that the violation of vector dominance predicted by the vector manifestation significantly suppresses dilepton yields compared to traditional assumptions.

Contribution

It demonstrates the impact of vector manifestation's violation of vector dominance on dilepton production, providing new insights into in-medium rho meson behavior.

Findings

Strong violation of vector dominance suppresses dilepton rates

Dropping rho effects are significant in thermal dilepton production

Results differ from models assuming vector dominance

Abstract

In this write-up we summarize the main result of our analysis on the thermal dilepton production rate from the dropping rho based on the vector manifestation (VM). In the analysis, we showed that the effect of the strong violation of the vector dominance (VD) predicted by the VM, substantially suppresses the dilepton production rate compared with the one predicted by assuming the VD together with the dropping rho.
