* KASCADE collaboration, only 2 papers included with main contribution of the CRD group. The Armenian KASCADE group developed methodology for multivariate data analysis for high-energy physics and astrophysics experiments; new methods were included the ANI (Analysis and Nonparametric Inference) computer code library, which has been extensively used during the last few decades for multidimensional analysis of data from modern cosmic ray detectors, especially for KASCADE and WIPPLE experiments. The methodology of the event-by-event analysis of the Extensive Air Shower experiments, introduced by him allows the estimation of the energy spectra of the separate groups of primary nucleolus (only the all-particle spectrum was prior to that); the partial spectra of primary cosmic rays measured by MAKET-ANI and KASCADE detectors prove the mass-dependent position of the knee and helps to develop particle acceleration models in Supernovae explosions now confirmed by gamma ray observatories on board of AGILE and FERMI satellites. A.Chilingarian introduce a new probability distribution for calculation of chance probability for the “peak” detection in searches of “new physics”.  Using his criteria instead of “Gaussian” chance probabilities will help to avoid fake inference usually occurred when dealing with small statistics and applying multiple cuts. 

**MAGIC experiment: Armenian group introduced the "multidimensional nonlinear cuts" method for analyzing data from the Atmospheric Cherenkov Telescopes (ACT); these techniques help to reliably proof existence of the flux of very high- energy gamma rays from the Crab nebula measured by the Whipple Cherenkov telescope thus establishing the new window to the Universe. Also Armenian group introduced the concept of the ACT system established later at Canarian islinds (HEGRA, MAGIC) in US (VERITAS) and South Africa ( HESS).
