      abstract     = {A fundamental property of particles and antiparticles (such
                      as electrons and positrons, respectively) is their ability
                      to annihilate one another. A similar behaviour is predicted
                      for magnetic solitons1—localized spin textures that can be
                      distinguished by their topological index Q. Theoretically,
                      magnetic topological solitons with opposite values of Q,
                      such as skyrmions2 and their antiparticles (namely,
                      antiskyrmions), are expected to be able to continuously
                      merge and annihilate3. However, experimental verification of
                      such particle–antiparticle pair production and
                      annihilation processes has been lacking. Here we report the
                      creation and annihilation of skyrmion–antiskyrmion pairs
                      in an exceptionally thin film of the cubic chiral magnet of
                      B20-type FeGe observed using transmission electron
                      microscopy. Our observations are highly reproducible and are
                      fully consistent with micromagnetic simulations. Our
                      findings provide a new platform for the fundamental studies
                      of particles and antiparticles based on magnetic solids and
                      open new perspectives for practical applications of thin
                      films of isotropic chiral magnets.},
