“…for individual showers is appropriate. The exception is k L , where we find (not unexpectedly [29,31,32]) that variations from the mean fitted valuesk L are large, particularly at high energies. These fluctuations will dominate the radiation pattern in the regime where longitudinal decoherence dominates, which at the highest energies is everywhere except within a small fraction of a degree from θ C .…”

“…The agreement between both simulations of the development is remarkable and in particular the multi-peaked structure characteristic of showers in dense media with energies well above the LPM scale [29] is extremely well reproduced. This gives us confidence in the reliability of our thinned simulations.…”

“…Also, and as we have previously mentioned, L is dependent upon the shower energy E 0 , so that the "constant" k L is in fact energy-dependent. For sufficiently low-energy showers, the dependence of L on E 0 is small, while at energies where LPM-elongation is significant (typically for E 0 E LP M ), L increases rapidly with E 0 [27,29,31,32]. Thus we expectk L to be fit well by the following relation:…”

“…The frequencies ν L and ν R will be inversely proportional to the time delays δt L and δt R , which are in turn functions of L and R. The amplitude A of the fully coherent (low-frequency) component will be proportional to the total excess tracklength T . The proportionalities of L, R, and T with properties of the interaction medium are well-established theoretical results [17,20,29,30]. We use the formalism of Alvarez-Muñiz et al [16]:…”

This paper presents our results for full 3-D simulations of very-high to ultra-high energy electromagnetic cascades -and the associated coherent Cherenkov radiation -as might be produced by high-energy neutrino interactions in dense media. Using "thinning" techniques, we develop an algorithm based on the existing "ZHS" code, and demonstrate that the new "ZHS-thinned" code can produce fast and accurate results for showers up to 10 20 eV. Using ZHS-thinned, we develop new parameterisations for the radiation from showers in ice, salt, and the lunar regolith, with a separate treatment of the megaregolith (deep regolith). Our parameterisations include for the first time a method to simulate fluctuations in shower length induced by the LPM effect. Our results, which avoid the pit-falls of scaling simulations from lower energies, allow improved calculations of the detection probability for experiments searching for high-energy neutrinos using the radio technique.

“…The experimental confirmation of the LPM effect at Stanford Linear Accelerator Center (SLAC) [144,145] has motivated new analyses of its consequences in cosmic ray physics [146][147][148][149][150]. The most evident signatures of the LPM effect on shower development are a shift in the position of the shower maximum X max and larger fluctuations in the shower development.…”

High energy physics in the atmosphere: phenomenology of cosmic ray air showers

et al. 2004

View full text Add to dashboard Cite

The properties of cosmic rays with energies above 10 6 GeV have to be deduced from the spacetime structure and particle content of the air showers which they initiate. In this review we summarize the phenomenology of these giant air showers. We describe the hadronic interaction models used to extrapolate results from collider data to ultra high energies, and discuss the prospects for insights into forward physics at the LHC. We also describe the main electromagnetic processes that govern the longitudinal shower evolution, as well as the lateral spread of particles. Armed with these two principal shower ingredients and motivation from the underlying physics, we provide an overview of some of the different methods proposed to distinguish primary species. The properties of neutrino interactions and the potential of forthcoming experiments to isolate deeply penetrating showers from baryonic cascades are also discussed. We finally venture into a terra incognita endowed with TeV-scale gravity and explore anomalous neutrino-induced showers.
