collider

The use of an asymmetric 'collider' to produce B particles was first proposed in 1987 by Pier Oddone, then head of Berkeley Lab's Physics Division and now one of the Lab's deputy directors.

For technical reasons, it is easier to do that test at RHIC by colliding deuterons accelerated in one of the 'collider' 's two rings with heavy nuclei in the other ring.

You need to smash two beams head-on in a 'collider' , because the center-of-mass energy is the sum of the energies in the two beams.

It is important too, for use in high-luminosity linear electron - positron 'colliders' where the focus is extremely tight, to know whether or not detectors can separate collision results from background radiation.

But how can we ever hope to make meaningful measurements at this scale when we have such difficulty building particle 'colliders' to work at the comparatively lowly Higgs scale?
