英文摘要"Twisted particles" refer to non-plane-wave states of photons, electrons, hadrons, or any other particles which carry nonzero, adjustable orbital angular momentum with respect to their average propagation direction. Twisted photons and electrons have already been experimentally demonstrated, and one can expect creation of twisted states of other particles in the future. Such states can be brought in collisions, offering a completely new degree of freedom in collider experiments and, especially, a novel tool for hadronic physics. We recently showed that 2 -> 1 processes with two twisted particles such as resonance production in twisted e(+)e(-) annihilation give access to observables which are difficult or impossible to probe in the usual plane wave collisions. In this paper, we discuss in detail surprising kinematic features of this process, focusing on spinless particle annihilation. They include 1) a new dimension in the final momentum space available in twisted annihilation, 2) interference fringes emerging in the cross section as a function of the total energy, and 3) the built-in mass spectrometric capability of this process, that is, simultaneous production and automatic angular separation of several resonances with different masses in monochromatic twisted particle annihilation experiment running at fixed energy. All these features cannot be obtained in the usual plane wave collision setting.
