Query: New scenarios of high-energy particle collisions near wormholes   We suggest two new scenarios of high-energy particle collisions in the
background of a wormhole. In scenario 1 the novelty consists in that the effect
does not require two particles coming from different mouths. Instead, all such
scenarios of high energy collisions develop, when an experimenter sends
particles towards a wormhole from the same side of the throat. For static
wormholes, this approach leads to indefinitely large energy in the center of
mass. For rotating wormholes, it makes possible the super-Penrose process
(unbounded energies measured at infinity). In scenario 2, one of colliding
particles oscillates near the wormhole throat from the very beginning. In this
sense, scenario 2 is intermediate between the standard one and scenario 1 since
the particle under discussion does not come from infinity at all.
