      abstract     = {HALHF is a hybrid linear collider that uses electron-driven
                      plasma-wakefield acceleration to accelerate electrons to
                      high energy while using radio-frequency cavity technology to
                      accelerate positrons. The most cost-effective solution
                      collides low-energy positrons with high-energy electrons,
                      producing a boost to the final state in the electron
                      direction with $\gamma= 1.67$. The current HALHF baseline
                      design produces a luminosity comparable to that of the
                      baseline ILC but with a greatly reduced construction and
                      carbon footprint and hence much lower cost than the mature
                      linear-collider designs ILC and CLIC. Costs for HALHF are
                      evaluated, together with that for the approximate 15-year
                      R\&D programme necessary to realise HALHF. Time scales and
                      cost for the R\&D are estimated. Upgrade paths for HALHF
                      technology from a 250~GeV Higgs factory, through 380 and
                      550~GeV, up to 10~TeV are sketched.},
