Modelling of narrow air showers

January 1989
Acta Physica Polonica Series B 20:885-893

Authors:

Calculations are made for the distributions of central densities (of electromagnetic particles) by integrating over radii R ≈ 0.4 m and R ≈ 0.8 m, and for the spectrum over the total number of particles in a shower, as well as for the distributions of the fractions of the total number of particles in a detector exhibiting maximum count rate setting the thresholds to be Nc >= 170 and Nc >= 625 particles. Comparison with the experimental data is performed.

A Search for Very High Energy Muons (Em > 100 TeV) in EAS around the Knee

June 2003

A possible explanation of the "knee" in the extensive air shower (EAS) spectrum is a change of hadron-hadron interactions. One of such scenarios suggests a threshold production of new heavy particles or states of matter at the knee energy. If the appearance of the knee is related to these new objects, their decays should give considerable rise to very high energy muons, whose energy is not ... [Show full abstract] measured with existing EAS arrays without using special detectors for muon energy determination. In order to check this hypothesis, simultaneous evaluation of muon energy and the energy of EAS is required. The experiment to search for such muons in EAS was started at Baksan Neutrino Observatory in September 2002. The energy of muons in our experiment is estimated by means of the Baksan Underground Scintillation telescope (BUST), and the EAS electromagnetic component is measured by the "Andyrchy" array, which is located straight above the BUST.

Measurement of the Muon Production Depths at the Pierre Auger Observatory

September 2016 · The European Physical Journal Plus

Laura Collica

The muon content of extensive air showers is an observable sensitive to the primary composition and to the hadronic interaction properties. The Pierre Auger Observatory uses water-Cherenkov detectors to measure particle densities at the ground and therefore is sensitive to the muon content of air showers. We present here a method which allows us to estimate the muon production depths by ...

The analysis is performed in a large range of zenith angles, thanks to the capability of estimating and subtracting the electromagnetic component, and for energies between
