Muon Identification without Iron

TL;DR

This paper demonstrates a method for muon identification and reconstruction using a detector with dual readout calorimeter and dual solenoid, achieving high efficiency and pion rejection without iron.

Contribution

It introduces a novel muon detection technique that does not rely on iron, using dual readout calorimeter and magnetic field calculations for improved particle identification.

Findings

Muon rejection factor of 10^3 at 20 GeV/c

Muon rejection factor of 10^5 at 300 GeV/c

High efficiency and purity in muon identification

Abstract

Muons can be identified with high efficiency and purity and reconstructed with high precision is a detector with a dual readout calorimeter and a dual solenoid to return the flux without iron. We shown CERN test beam data for the calorimeter and calculations for the magnetic fields and the track reconstruction. For isolated tracks, the rejection of pions against muons ranges from $10^3$ at 20 GeV/c to $10^5$ at 300 GeV/c.
