Self Interacting Dark Matter in the Solar System
Avijit K. Ganguly, Pankaj Jain, Subhayan Mandal +1
Weakly coupled, almost massless, spin 0 particles have been predicted by many extensions of the standard model of particle physics. Recently, the PVLAS group observed a rotation of…
Classifying Polarization Observables of the Cosmic Microwave Background
John P. Ralston, Pankaj Jain
We revisit the classification of polarization observables of the cosmic microwave background. There exists a unified approach to the density matrix by which intensity,…
Two Photon Exchange Contributions to Elastic ep Scattering in the Nonlocal Field Formalism
Pankaj Jain, Satish D. Joglekar, Subhadip Mitra
We construct a nonlocal gauge invariant Lagrangian to model the electromagnetic interaction of proton. The Lagrangian includes all allowed operators with dimension up to five. We c…
A re-analysis of the three-year WMAP temperature power spectrum and likelihood
H. K. Eriksen, Greg Huey, R. Saha +11
We analyze the three-year WMAP temperature anisotropy data seeking to confirm the power spectrum and likelihoods published by the WMAP team. We apply five independent implementatio…
Interferometric Parallax: A Method for Measurement of Astronomical Distances
Pankaj Jain, John P. Ralston
We show that distances of objects at cosmological distances can be measured directly using interferometry. Our approach to interferometric parallax comes from analysis of 4-point a…
