Mississippi State Axion Search: A Light Shining though a Wall ALP Search

Prajwal Mohanmurthy, Dipangkar Dutta, Joseph Formaggio +8

The elegant solutions to the strong CP problem predict the existence of a particle called axion. Thus, the search for axion like particles (ALP) has been an ongoing endeavor. The p…

Analysis of large-scale anisotropy of ultra-high energy cosmic rays in HiRes data

R. U. Abbasi, T. Abu-Zayyad, M. Allen +59

Stereo data collected by the HiRes experiment over a six year period are examined for large-scale anisotropy related to the inhomogeneous distribution of matter in the nearby Unive…

Search for Point Sources of Ultra--High-Energy Cosmic Rays Above 10^19 eV Using a Maximum Likelihood Ratio Test

Stefan Westerhoff, Chad B. Finley

We present the results of a search for cosmic ray point sources at energies above 10^19 eV in the HiRes stereo data set. The analysis is based on a maximum likelihood ratio test us…
