A Quantum Phase Transition in the Cosmic Ray Energy Distribution
A. Widom, J. Swain, Y. Srivastava
We here argue that the "knee" of the cosmic ray energy distribution at PeV represents a second order phase transition of cosmic proportions. The discontinuity of the h…
Entropy and the Cosmic Ray Particle Energy Distribution Power Law Exponent
A. Widom, J. Swain, Y. N. Srivastava
We consider the hypothesis that cosmic rays are emitted from the surfaces of neutron stars by a process of evaporation from an internal nuclear liquid to a dilute external gas whic…
Concerning the Nature of the Cosmic Ray Power Law Exponents
A. Widom, J. Swain, Y. N. Srivastava
We have recently shown that the cosmic ray energy distributions as detected on earthbound, low flying balloon or high flying satellite detectors can be computed by employing the he…
Weak Interaction Neutron Production Rates in Fully Ionized Plasmas
A. Widom, J. Swain, Y. N. Srivastava
Employing the weak interaction reaction wherein a heavy electron is captured by a proton to produce a neutron and a neutrino, the neutron production rate for neutral hydrogen gases…
Detecting and Identifying Heavy Nuclei and Antinuclei with Standard Detectors
J. Swain, T. Paul, A. Widom +1
Most data gathered from high energy experiments at colliders are analyzed assuming that particles stable enough to not decay in the detector volume, and able to interact strongly o…
Production and detection of heavy matter anti-matter from Higgs decays
Y. N. Srivastava, A. Widom, J. Swain
The one-loop Higgs coupling to two gluons has been invoked in the past to estimate that the fraction of the nucleon mass which is due to the Higgs is rather small but calculable (a…
Asymptotic High Energy Total Cross Sections and Theories with Extra Dimensions
J. Swain, A. Widom, Y. Srivastava
The rate at which cross sections grow with energy is sensitive to the presence of extra dimensions in a rather model-independent fashion. We examine how rates would be expected to…
On the nature of cosmic rays above the Greisen--Zatsepin--Kuz'min cut off
L. A. Anchordoqui, M. Kirasirova, T. P. McCauley +2
A re-examination of the atmospheric cascade profile of the highest energy cosmic ray is presented. The study includes air-shower simulations considering different cross sections, p…
Fractal Electromagnetic Showers
L. A. Anchordoqui, M. Kirasirova, T. P. McCauley +3
We study the self-similar structure of electromagnetic showers and introduce the notion of the fractal dimension of a shower. Studies underway of showers in various materials and a…
A pot of gold at the end of the cosmic "raynbow"?
L. A. Anchordoqui, M. T. Dova, T. P. McCauley +3
We critically review the common belief that ultrahigh energy cosmic rays are protons or atomic nuclei with masses not exceeding that of iron. We find that heavier nuclei are indeed…
Studies of Avalanche Photodiode Performance in a High Magnetic Field
J. Marler, T. McCauley, S. Reucroft +3
We report the results of exposing a Hamamatsu avalanche photodiode (APD) to a 7.9 Tesla magnetic field. The effect of the magnetic field on the gain of the APD is shown and discuss…
Real Time Radiative Corrections to Charged Particle Decay Laws
A. Widom, J. Swain, Y. N. Srivastava
The real time exponential decay laws for meta-stable charged particles are shown to require radiative corrections. The methods employed are well known to be valid for radiatively c…
Radiative Tau Lepton Pair Production as a Probe of Anomalous Electromagnetic Couplings of the Tau
S. S. Gau, T. Paul, J. Swain +1
We calculate the squared matrix element for the process e+ e- --> tau+ tau- gamma allowing for anomalous magnetic and electric dipole moments at the tau tau gamma vertex. No interf…
Numerical Construction of Likelihood Distributions and the Propagation of Errors
J. Swain, L. Taylor
The standard method for the propagation of errors, based on a Taylor series expansion, is approximate and frequently inadequate for realistic problems. A simple and generic techniq…
A Method to Determine the Tau Neutrino Helicity Using Polarized Taus
M. -T. Dova, L. N. Epele, H. Fanchiotti +3
A method is presented to extract the tau neutrino helicity, or equivalently, the chirality parameter , independent of any tau polarization which may be present. Th…
