  This Multi-Petawatt Physics Prioritization (MP3) Workshop Report captures the
outcomes from a community-initiated workshop held April 20-22, 2022 at Sorbonne
University in Paris, France. The MP3 workshop aimed at developing science
questions to guide research and future experiments in four areas identified by
corresponding MP3 working groups: high-field physics and quantum
electrodynamics (HFP/QED), laboratory astrophysics and planetary physics
(LAPP), laser-driven nuclear physics (LDNP), and particle acceleration and
advanced light sources (PAALS).
