Assessment of characteristics of threshhold and neural network triggers for b-quarks events selection using simulation data for the forward calorimeter of multiparticle spectrometer installation on UNK 3 TeV proton beam; Kharakteristiki porogovykh i nejrosetevogo triggerov otbora sobytij s b-kvarkami na osnove model`nykh dannykh dlya perednego kalorimetra ustanovki `Mnogochastichnyj spektrometr` na puchke UNK s ehnergiej 3 TehV

Abstract

Basic characteristics of a set of calorimeter triggers for b-events selection (all modes of B-mesons decay) are investigated for fixed target experiments on 3 TeV proton beam using Monte-Carlo simulation data. Characteristics of a neural network trigger and simple threshold trigger witn modified decision functions are shown to remarkably surpass characteristics of conventional triggers. Background rejection factor 10-200 at efficiency 0.8-0.2 may be achieved with the proposed version of a neural network trigger operating on the forward calorimeter data (without using data from other detectors of the installation). This background rejection factor is 1.5-5 times higher compared to results published elsewhere. 20 refs., 15 figs.
