Searches for and Identiﬁcation of New Neutral Gauge Z Bosons at the International Linear Electron–Positron Collider A. A. Babich, A. A. Pankov, and N. V. Karpenko

The potential of the electron–positron International Linear Collider for searches for and the separation of signals induced by new neutral gauge bosons predicted by various classes of models featuring an extended gauge sector is investigated. The analysis presented in this article was performed for processes of annihilation fermion-pair production and was based on the use of diﬀerential polarization observables, which ensure a higher sensitivity (in relation to integrated observables) of the processes being considered to Z -boson parameters. Thresholds for discovering and identifying new neutral gauge bosons associated with models belonging to the E6 and LR, as well as the ALR and SSM, classes are determined. In particular, it is shown that polarization experiments at a 0.5-TeV electron–positron collider of integrated luminosity 100 fb−1 would , Zψ , Zη , Zχ , ZLRS , and make it possible to identify unambiguously the entire set of Z -boson models (ZSSM √ ZALR ) for MZ < 6 s and to improve considerably the respective estimates expected from experiments with unpolarized particles.

Investigation of the Spectrum of High-Energy Muons by the Multiple-Interaction Method on the Basis of Data from the Baksan Underground Scintillation Telescope A. G. Bogdanov, R. P. Kokoulin, Yu. F. Novosel’tsev, R. V. Novosel’tseva, V. B. Petkov, and A. A. Petrukhin

Experimental data obtained with the aid of the Baksan underground scintillation telescope over a long period of its operation are analyzed with the aim of searches for an excess ﬂux of ultrahigh-energy (≥100 TeV) muons. The multiple-interaction method, which is based on the ideas of the pair-meter technique, is used to analyze the energy spectrum of muons. Phenomenological parameters and the sensitivity of this method to the shape of the spectrum are discussed. The experimental distributions are compared with the results of the calculations for various versions of the muon spectrum. The possibility of separating ultrahigh-energy muons ﬂying in the vicinity of the axis of extensive air showers is assessed on the basis of the integrated number of large energy depositions in recorded and simulated events.

Radio-Wave Emission from Extensive Air Showers as a Method for Detecting Cosmic Rays N. N. Kalmykov and A. A. Konstantinov

At the present time, radio-wave emission from extensive air showers is being considered as a new promising method for detecting cosmic rays of energy in the region E0 > 5 × 1016 eV. Radio-wave emission from an extensive air shower whose development is simulated by the Monte Carlo method is calculated here. The ﬁeld of radio-wave emission from an extensive air shower is calculated on the basis of two representations of a shower: as a set of individual particles and as a continuous set of currents. The sensitivity of features of r
