Magnetic Monopole Phenomenology at Future Hadron Colliders (2404.10871v1)

Abstract: In the grand tapestry of Physics, the magnetic monopole is a holy grail. Therefore, numerous efforts are underway in search of this hypothetical particle at CMS, ATLAS and MoEDAL experiments of LHC by employing different production mechanisms. The cornerstone of our comprehension of monopoles lies in Dirac's theory which outlines their characteristics and dynamics. Within this theoretical framework, an effective $U(1)$ gauge field theory, derived from conventional models, delineates the interaction between spin magnetically-charged fields and ordinary photons under electric-magnetic dualization. The focus of this paper is the production of magnetic monopoles from Drell-Yan and the Photon-Fusion mechanisms to produce velocity-dependent scalar, fermionic, and vector monopoles of spin angular momentum $0,\frac{1}{2},1$ respectively at LHC. A computational work is performed to compare the monopole pair-production cross-sections for both methods at different center-of-mass energies ($\sqrt{s}$) with various magnetic dipole moments. The comparison of kinematic distributions of monopoles at Parton and reconstructed level are demonstrated including both DY and PF mechanisms. Extracted results showcase how modern machine-learning techniques can be used to study the production of magnetic monopoles at the Future proton-proton Particle Colliders at 100 TeV. We demonstrate the observability of magnetic monopoles against the most relevant Standard Model background using multivariate methods such as Boosted Decision Trees (BDT), Likelihood, and Multilayer Perceptron (MLP). This study compares the performance of these classifiers with traditional cut-based and counting approaches, proving the superiority of our methods.
