Description
A future far detector at Belle II - GAZELLE - could enhance the search potential for long-lived particles at electron-positron experiments. An initiative of theorists and experimentalists has explored this potential for three common LLP scenarios with different production mechanisms. In this talk, we compare the projections of finding these LLPs at Belle II or GAZELLE. Due to Belle II's excellent sensitivity to LLPs, we find little extra gain in building a far detector like GAZELLE.
