Abstract

KASCADE-Grande was an air-shower experiment aimed to investigate cosmic rays between 1016and 1018eV. The instrument was located at the site of the Karlsruhe Institute of Technology, Germany at an altitude of 110 m a.s.l. and covered an area of 0.5 km2. KASCADE-Grande consisted of several detector systems dedicated to measure different components of the cosmic ray induced air showers, e.g. the muon content (Eth> 230 MeV) and the number of charged particles (Eth> 3 MeV) at ground, which are the basis for several energy and composition studies of cosmic rays. In this contribution, using these observables, the KASCADE-Grande data is divided into light and heavy mass groups and their respective muon densities are reconstructed at different zenith angle intervals. The results are compared with the expectations of the post-LHC hadronic-interaction models, EPOS-LHC and QGSJET-II-04, in order to test the validity of the model predictions.

Abstract

Aims. We want to understand the emission mechanism of radio emission from air showers to determine the origin of high-energy cosmic rays. Therefore, we study the geometry of the air shower radio emission measured with LOPES and search for systematic effects between the direction determined on the radio signal and the direction provided by the particle detector array KASCADE.

Abstract

Context.The detection of radio pulses from cosmic ray air showers is a potentially powerful new detection mechanism for studying spectrum and composition of ultra high energy cosmic rays that needs to be understood in greater detail. The radiation consists in large part of geosynchrotron radiation. The intensity of this radiation depends, among other factors, on the energy of the primary particle and the angle of the shower axis with respect to the geomagnetic field.

Abstract

Aims.The capability of radio antenna arrays to measure cosmic ray air showers with very large zenith angles is explored. This is important, since a possible neutrino detection has to fulfill two requirements. First: antennas should be able to detect very inclined cosmic ray air showers, and second: it should be possible to estimate the distance to the shower maximum, since neutrinos are most likely to travel far through the Earth's atmosphere without interaction and induce air showers close to the ground.

Abstract

The KASCADE-Grande experiment operated at KIT from January 2004 to November 2012, measuring Extensive Air Showers (EAS) generated by primary cosmic rays in the 1016–1018eVenergy range. The experiment measured, for each single event, with a high resolution, the total number of charged particles (Nch) and of muons (Nμ).

7. Hadronic interactions and EAS muon pseudorapidities investigated with the Muon Tracking Detector in KASCADE-Grande

Subjects
*NUCLEAR track detectors, *COLLISIONS (Nuclear physics), *HADRONS, *MUONS, *COSMIC ray showers, *LONGITUDINAL method
Abstract

The Muon Tracking Detector in the KASCADE-Grande EAS experiment allows the precise measurement of shower muon directions up to 700 m distance from the shower center. This directional information is used to study the pseudorapidity of muons in EAS, closely related to the pseudorapidity of their parent mesons. Moreover, the mean value of muon pseudorapidity in a registered shower reflects the longitudinal development of its hadronic component. All of this makes it a good tool for testing hadronic interaction models. The possibilities of such tests given by the KASCADE-Grande experimental setup are discussed and an example of the obtained muon pseudorapidity spectrum is shown. [Copyright &y& Elsevier]

The possibility to test hadronic interaction models, to study primary mass composition and parameters of hadronic interactions with these distributions is discussed. [Copyright &y& Elsevier]

Abstract

Tangential and radial angles of muons in EAS, a useful concept in the investigation of the muon production height, can also be used for the investigation of the muon momenta. A parameter ζ, being a combination of tangential and radial angles, is introduced and its possible applications in investigating muons in showers are presented. [Copyright &y& Elsevier]

Abstract

We report on the first exclusive measurement of the 2πproduction in NN collisions atTp=750 MeV using a H2cluster jet target and the WASA/PROMICE detector at CELSIUS. In the invariant-mass spectrumwe observe a narrow peak at 2.063(2) GeV with a 4σdeviation relative to the MC simulations for the conventional nonresonant 2πproduction process. The finding is in agreement with the hypothesis of a narrowπNN resonance withI(JP)=even (0−), calledd′, postulated recently to describe the peculiar resonance-like behavior of the pionic double charge exchange on nuclei.
