The GRAPES-3 experiment observes extensive air showers using a high-density
array of scintillation detectors and a large area tracking muon detector. We have
studied the relationship between the muon multiplicity distribution and
shower size for the GRAPES-3 data taken during the period of 2000 - 2003.
Monte Carlo simulations using CORSIKA code were performed to extract the
spectra for vario

Properties of high-energy hadronic interactions can be studied by
measurements of the attenuation lengths of hadrons in air showers.
The hadronic, electromagnetic, and muonic components of air showers
are registered with the KASCADE-Grande experiment. Different methods
are applied to derive attenuation lengths of hadrons from the
measurements. a) The flux of unaccompanied hadrons at ground l

The current status and prospects of deducing the proton-air cross section from
fluorescence telescope measurements of extensive air showers is discussed. As it is
not possible to observe the point of first interaction, X_1, directly, other
observables closely linked to X_1 must be inferred from the measured longitudinal
profiles. This introduces a dependence on the models used to describe the

Motivated by the importance of the measurement of p+C and pi+C interactions for
tuning hadronic interaction models used in neutrino flux and extensive air shower
simulations, we analyze pion production in p+C and pi+C reactions at 12GeV/c measured
in the fixed target experiment HARP at CERN-PS. We present momentum spectra of
positive and negative pions in the momentum range from 0.5GeV/c to 8.

We present proton-air inelastic cross-section measurement at ultra-high energy using
all available data
collected by the High Resolution Fly's Eye stereo fluorescence detector. A
significantly improved
data reconstruction procedure allows us to minimize the data quality cuts. This
increases the data
statistics available for the measurement and consequently reduces the statistical
error. T

Cosmic ray physics in the 10^(12)-10^(15) eV primary energy range is among the main
scientific goals of the ARGO-YBJ experiment. The detector, located in the Cosmic Ray
Observatory of Yangbajing (Tibet, China) at 4300m a.s.l., is a full coverage
Extensive Air Shower array consisting of a carpet of Resistive Plate Chambers (RPC)
of about 5800m^2.
The apparatus layout, performance and locati

The study of the energy dependence of the depth of shower maximum
and of the muon content in high energy cosmic ray showers are two widely
used methods for the derivation of cosmic ray composition. An alternative
interpretation of the energy dependence of these two observables is
a change in the features of hadronic interactions at high energy.
In this contribution we show that the string per
