An importance of twisted (vortex) particles in heavy-ion collisions is analyzed. Free twisted photons and electrons can possess giant intrinsic orbital angular momenta. Twisted photons have a nonzero effective mass [1] and are spatially localized. They are naturally radiated at a spiral motion of charges, are rather ubiquitous in laboratories and nature [2,3], and can be emitted, like other twisted particles, in heavy-ion collisions. Charged twisted particles can be recognized by their dynamics and specific effects [4] in external fields.
