Search for long-lived particles using displaced vertices of oppositely charged leptons in 140fb−1 of pp collisions at s=13 TeV with the ATLAS detector

A search is presented for long-lived particles decaying into an oppositely charged lepton pair, mu(+)mu(-), e(+)e(-), or e(+/-)e(-/+), that form a vertex within the inner tracking system of the ATLAS detector at the Large Hadron Collider, displaced from t
