Dark Energy in an Axion Model with Explicit Z(N) Symmetry Breaking
Pankaj Jain
We point out that a well known axion model with an explicit Z(N) symmetry breaking term predicts both dark energy and cold dark matter. We estimate the parameters of this model whi…
The Dynamical Mixing of Light and Pseudoscalar Fields
Sudeep Das, Pankaj Jain, John P. Ralston +1
We solve the general problem of mixing of electromagnetic and scalar or pseudoscalar fields coupled by axion-type interactions ${\cal L}_{int} =g_ϕ ϕε_{μν\a \b}F^{μν}F^{\a \b} $. T…
Probing Light Pseudoscalars with Light: Propagation, Resonance and Spontaneous Polarization
Sudeep Das, Pankaj Jain, John P. Ralston +1
Radiation propagating over cosmological distances can probe light weakly interacting pseudoscalar (or scalar) particles. The existence of a spin-0 field changes the dynamical symme…
Two Graviton Production at and Hadron Hadron Colliders in the Randall-Sundrum Model
Pankaj Jain, Sukanta Panda
We compute the pair production cross section of two Kaluza Klein modes in the Randall-Sundrum model at and hadron hadron colliders. These processes are interesting because…
