摘要

In quantum gravity theories Planckian behavior is triggered by the energy of{\it elementary} particles approaching the Planck energy, $E_P$, but it's alsopossible that anomalous behavior strikes systems of particles with total energynear $E_P$. This is usually perceived to be pathological and has been labelled``the soccer ball problem''. We point out that there is no obviouscontradiction with experiment if {\it coherent} collections of particles withbulk energy of order $E_P$ do indeed display Planckian behavior, a possibilitythat would open a new experimental window. Unfortunately field theoryrealizations of deformed special relativity never exhibit a ``soccer ballproblem''; we present several formulations where this is undeniably true. Uponcloser scrutiny we discover that the only chance for Planckian behavior to betriggered by large coherent energies involves the details of secondquantization. We find a formulation where the quanta have their energy-momentum(mass-shell) relations deformed as a function of the bulk energy of thecoherent packet to which they belong, rather than the frequency. Given ongoingdevelopments in Laser technology, such a possibility would be of greatexperimental interest.
