1 Multi-vertex interpretation

Jet-vertex association approaches
* Track z0 (weighted) averages
* DBSCAN clustering in z0, eta, phi
* 3D track-jets

Speaker: Mirella Vassilev (SLAC)

2 GNN PU jet suppression using HS vertices

Per-jet classification: Use HS vertex + all tracks matched to the jet

Speakers: Mirella Vassilev (SLAC), Wasikul Islam (Univ. of Wisconsin & SLAC)

3 GNN PU suppression using many vertices

Per-event classification: Use jet-vertex association and multi-vertex selection

Speakers: Mirella Vassilev (SLAC), Wasikul Islam (Univ. of Wisconsin & SLAC)
