Virtual Black Holes at Linear Colliders
(May 2002)Abstract
We propose that future linear colliders can create virtual black holes even
though their energies are below the fundamental scale, because of the
uncertainty principle. These virtual black holes provide us much information
which cannot be obtained in the production of black holes at the LHC or other
hadron colliders. We can observe lepton flavor and lepton (baryon) number
violating processes at linear colliders by using virtual black holes. And
virtual black holes can be used to the precision measurements of top and W.
They can create only one top quark or one W boson, which leads to the clean
signal that cannot be obtained in pair-production processes.
