Ultra High Energy Cosmic Rays from Early Decaying Primordial Black Holes
Pankaj Jain, Sukanta Panda
Origin of ultra high energy cosmic rays is an unsolved problem. Several proposals such as Z-burst, decay of super massive matter, susy particles as a primary, neutrino as a primary…
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…
Universality and Scale Invariance in Hourly Rainfall
Pankaj Jain, Suman Jain, Gauher Shaheen
We show that the hourly rainfall rate distribution can be described by a simple power law to a good approximation. We show that the exponent of the distribution in tropics is unive…
Perturbative Color Transparency in Electron Beam Experiments via Impact-Parameter Factorization
John P. Ralston, Pankaj Jain, Bijoy Kundu +1
Color transparency is a prediction of perturbative QCD. Yet detailed calculations have been lacking, and aspects of the required factorization have been controversial. We report on…
Hadronic electromagnetic form factors and color transparency
Bijoy Kundu, Pankaj Jain, John P. Ralston +1
We review the current status of electromagnetic form factor calculations in perturbative QCD. There is growing evidence that factorization prescriptions involving a transverse coor…
Core, Mantle, Crust: Imaging the Earth's Interior with Ultra-High Energy Neutrino Tomography
John P. Ralston, Pankaj Jain, George M. Frichter
We report on the feasibility of using an isotropic flux of cosmic neutrinos in the energy range of 10 to 10,000 TeV to study the interior geophysical structure of the Earth. The an…
