The statistical multidimensional combined algorithm for selecting the electron and pion events, which is based on different spatial electromagnetic and hadronic shower developments is proposed. The ...method has been tested on the basis of the test beam data of the ATLAS tile iron-scintillator hadronic calorimeter and demonstrated its efficiency (impurities are below 0.2%). The proposed algorithm can be used to analyze the data of the modern combined calorimeters like the ATLAS and CMS detectors at the LHC.
A model of hadron (proton) as a coherent state of transverse excitations on the horosphere in momentum space identified with partons is presented. The features of multiparticle production resulting ...from the existence of theoretical and experimental constants characterizing the processes with high multiplicity at the LHC are investigated.

We suggest a new non-parametrical hadron energy reconstruction algorithm for a combined calorimeter. It uses only the known values of non-compensation (
e/
h ratios) and the electron calibration ...constants of the electromagnetic and hadronic compartments of a calorimeter. We demonstrate its performance using the experimental data of the ATLAS prototype combined calorimeter.
The extension of the longitudinal hadronic shower profile parameterization which takes into account non-compensations of calorimeters and the algorithm of the longitudinal hadronic shower profile ...curve making for a combined calorimeter are suggested. The proposed algorithms can be used for data analysis from modern combined calorimeters like the ATLAS detector at the LHC.
A fully instrumented slice of the ATLAS detector was exposed to test beams from the SPS (Super Proton Synchrotron) at CERN in 2004. In this paper, the results of the measurements of the response of ...the barrel calorimeter to hadrons with energies in the range 20–350
GeV and beam impact points and angles corresponding to pseudo-rapidity values in the range 0.2–0.65 are reported. The results are compared to the predictions of a simulation program using the Geant 4 toolkit.
The analytical representation of the longitudinal hadronic shower development from the face of a calorimeter is presented and compared with the experimental data. The suggested formula is ...particularly useful for designing, testing and calibrating a huge calorimeter complex like in ATLAS at LHC.
The formulae for correlators K2 and K3 of a given particle observable (e.g. energy or transverse momentum) accounting for the track reconstruction efficiency are presented. Similar to the case of an ...ideal detector, the correlators can be expressed through the event-by-event fluctuation of the observable single event mean and the observable pseudo-central moments. However, on the contrary to the ideal case, this splitting does not allow for a substantial reduction of the computation time.
Part.Nucl.Lett. 100 (2000) 28-34 The method of extraction of the e/h ratio for an electromagnetic compartment
of a combined calorimeter is suggested and the non-compensation was determined.
The ...results agree with the Monte Carlo prediction and results of the weighting
method for electromagnetic compartment of combined calorimeter. The new easy
method of a hadronic energy reconstruction for a combined calorimeter is also
suggested. The proposed methods can be used for a combined calorimeter, which
is being designed to perform energy measurement in a next-generation high
energy collider experiment like ATLAS at LHC.
