Query: Physics Opportunities for the Fermilab Booster Replacement   This white paper presents opportunities afforded by the Fermilab Booster
Replacement and its various options. Its goal is to inform the design process
of the Booster Replacement about the accelerator needs of the various options,
allowing the design to be versatile and enable, or leave the door open to, as
many options as possible. The physics themes covered by the paper include
searches for dark sectors and new opportunities with muons.
