Muon Pair Production from Electron-Positron and Positronium Annihilation in Polarized Laser Field

Abstract

This thesis investigates muon pair production resulting from electron-positron annihilation and positronium interactions within polarized laser fields. The study systematically examines how various parameters of the laser field; specifically polarization, intensity, and photon energy affect the production rates and energy distributions of muon pairs. Through a series of computational simulations and sensitivity analyses, we established that increased laser intensity significantly enhances muon pair production rates, corroborating theoretical predictions from Quantum Electrodynamics (QED). Furthermore, the analysis reveals that circularly polarized light is more effective than linearly polarized light in facilitating muon pair production, underscoring the critical role of polarization in the interaction dynamics. Sensitivity analyses indicate that muon production rates are particularly responsive to changes in laser intensity and polarization, while variations in the initial energies of electron-positron pairs exert a comparatively minor influence. To validate these findings, future work is proposed, which includes experimental studies employing high-intensity laser systems to observe muon pair production under controlled conditions. The exploration of additional parameters, such as the energy distribution of the electron-positron pairs and varying laser wavelengths, is recommended to gain further insights into optimizing muon production. This thesis contributes to the growing body of research in high-energy particle physics, offering valuable insights for future experimental designs and the development of advanced laser systems aimed at enhancing muon production efficiencies.
