Physics Beyond the Standard Model

This research area focuses on leveraging current and future collider experiments, such as the LHC and its upgrades, to directly or indirectly probe signatures of new physics beyond the Standard Model (BSM). It integrates advances in experimental capabilities, effective field theory approaches, and quantum information measures—particularly through spin correlations and entanglement in top quark pairs—to expand the discovery potential for new particles, interactions, or dynamics not described by the SM. Understanding quantum observables like entanglement and Bell inequality violations becomes crucial for enhancing BSM sensitivity where classical signatures might fail.

This theme investigates novel theoretical models developed to address conceptual and empirical shortcomings of the Standard Model, such as neutrino masses, dark matter, gravity unification, and naturalness. These models often reconstruct the ontology of particles and fields, explore spacetime structure beyond four dimensions, or propose new mechanisms for mass generation and force unification. The research spans reconceptualizations like generation models unifying fermion families with gravity, harmonic quantization frameworks providing parameter-free derivations of particle properties, flexibly quantized spacetimes giving discrete time and varying fundamental constants descriptions, and topological extra dimensions influencing gravitational signatures.

This theme centers on high-precision theoretical work refining Standard Model predictions vital for interpreting current and future experimental data, alongside investigations of minimal scalar sector extensions that can stabilize the vacuum and address phenomenological tensions. Detailed radiative corrections, renormalization group running, and two-loop analyses quantify top, Higgs, and electroweak parameters, while phenomenological studies of models like SMASH explore threshold corrections to the Higgs quartic and triple couplings, linking vacuum metastability, neutrino masses, and axion physics to provide insights into possible BSM scalar dynamics.
