Description

We have developed the theory of interaction of classical plasma with Kaluza-Klein gravitons in the ADD model of TeV-scale gravity. Plasma is described within the kinetic approach as the system of charged particles and the Maxwell field both confined on the brane. Interaction with multidimensional gravity living in the bulk with $n$ compact extra dimensions is introduced within the Linearized theory. Our interest is in computing KK gravitons emission rates taking into account in a consistent way the plasma collective effects. Apart from bremsstrahlung (which turn out to be modified for certain frequencies by plasma effects) we have essentially found collective mechanisms of the KK gravitons production such as the coalescence of two Langmuir waves into graviton.
