Schwarzschild-like wormholes as accelerators

In this paper a wormhole W of an especially simple-and hence, hopefully, realistic-geometry is considered: it is static, spherically symmetric, its matter source is confined to a compact neighborhood of the throat, and the tt-component (in the Schwarzschild coordinates) of its metric has a single minimum. It is shown that such a wormhole is a "super accelerator," i.e., a pair of free-falling particles-with fixed energies at infinity-collide with the center-of-mass energy growing unboundedly with vertical bar g(tt) (min)vertical bar. The existence of such super accelerators would make it possible to observe otherwise inaccessible phenomena. In contrast to the rotating Teo wormhole, considered by Tsukamoto and Bambi, W cannot accelerate the collision products on their way to a distant observer. On the other hand, in contrast to the black hole colliders, W does not need such acceleration in order to make those products detectable.
