The Uncertainty Principle and Gribov Copies

Authors: Rajan Dogra

In this paper, it is shown that for the hard gluon emitted in 3-jet event, the existence of the Hamiltonian H on a particular gauge orbit is only for the infinitesimal time–period . During this infinitesimal time– period , the uncertainty principle implies that there must be certain minimum amount of uncertainty, or quantum fluctuation in the eigenvalue of the Hamiltonian H of the hard gluon emitted in 3-jet event. One can think of these quantum fluctuations as Gribov copies that appear at some time, move along with the real hard gluon and then get annihilated. Like virtual particles, Gribov copies cannot be observed directly with particle detectors, but their indirect effects like anomalous scaling can be observed and measured.
