      abstract     = {Particle physicists aim to construct a electron-positron
                      Higgs factory as the next major particle collider. However,
                      the high associated costs motivate the development of more
                      affordable collider designs. Plasma-wakefield acceleration
                      is a promising technology to this end. HALHF is a proposal
                      for a Higgs factory that utilizes beam-driven
                      plasma-wakefield acceleration to accelerate electrons to
                      high energy with high gradient, while using radio-frequency
                      acceleration to accelerate positrons to a lower energy. This
                      asymmetry sidesteps a major difficulty in plasma
                      acceleration: that of accelerating positrons with high
                      efficiency and quality. Since publication, several
                      challenges were identified in the original baseline design.
                      We summarize the updated baseline design, which addresses
                      these challenges, and describe the parameter- and
                      cost-optimization process used to arrive at this design.},
