Ideas about quantum gravity often postulate that at some high energy/momentum scale there will be a fixed, minimal length. Such a minimal length can be phenomenologically investigated by modifying the usual Heisenberg Uncertainty Relation-ship,…
In quantum gravity it is generally thought that a modified commutator of the form [(x) over cap, (p) over cap] = ih(1 + beta p(2)) is sufficient to give rise to a minimum length scale. We test this assumption and find that different pairs of modified…
