Ultra-High Energy Quenching of the LPM Effect: Implications for GZK-Violating Events
John P. Ralston, Soebur Razzaque, Pankaj Jain
Cosmic rays in the regime of 10^19-10^20 eV should not exist, according to the GZK bound. Conflicts between data and the bound have led to suggestions that laws of physics must be…
Exploring the Micro-Structure of the Proton: from Form Factors to DVCS
John P. Ralston, Pankaj Jain
For a long time people made the mistake of thinking the proton was understood. New experiments, ranging from form factors to deeply virtual Compton scattering, promise a new era of…
Electromagnetic Polarization Effects due to Axion Photon Mixing
Pankaj Jain, Sukanta Panda, S. Sarala
We investigate the effect of axions on the polarization of electromagnetic waves as they propagate through astronomical distances. We analyze the change in the dispersion of the el…
The Transverse Quark Distribution and Proton Electromagnetic Form Factors in Skew Distribution Formalism
Roman V. Buniy, Pankaj Jain, John P. Ralston
Skew density matrices can be diagonalized to yield probability interpretation. The power-counting prediction of perturbative QCD is found consistent with recent CEBAF data on $F_2(…
Electromagnetic Form Factors and the Localization of Quark Orbital Angular Momentum in the Proton
John P. Ralston, Roman V. Buniy, Pankaj Jain
A new picture is given of generalized parton distributions probed in experiments in which the probe scale and the momentum transfer $\DD^{2}$ are well separated. Applicatio…
Angular Dependence of Neutrino Flux in KM3 Detectors in Low Scale Gravity Models
Pankaj Jain, Supriya Kar, Douglas W. McKay +2
Cubic kilometer neutrino telescopes are capable of probing fundamental questions of ultra-high energy neutrino interactions. There is currently great interest in neutrino interacti…
