Proposed V-Pion Parameters for ATLAS Detector: A Comprehensive Overview

This document outlines the proposed parameters for V-Pion detection within the ATLAS detector framework. It details the dimensions and specifications of various detector layers, including pixel detectors, TRT, EM calorimeter, and hadronic calorimeter. Key decay parameters for Z' bosons and Higgs particles are also provided, highlighting V-Pion mass, lifetime, and decay behavior within the silicon layers of the detector. The study aims to enhance understanding of V-Pion production and decay, contributing to the broader research in particle physics.
