Description

Many well-motivated extensions of the Standard Model predict new, entirely bosonic sources of CP violation (CPV). In these scenarios, the simultaneous observation of carefully selected bosonic processes emerges as a simple yet powerful method to unambiguously reveal the presence of CPV. The present study, which establishes a promising framework of CPV searches for the upcoming HL-LHC era, showcases this method by exploring the detectability of such generic CPV signatures within the economical Complex Two-Higgs Doublet Model (C2HDM). Specifically, we assess the observation prospects for viable combinations of gluon fusion, vector boson fusion and V-associated production processes which unequivocally signal the existence of CP-violating couplings within the bosonic spectrum of the model. Finally, we discuss an ongoing extension of this work which completes the framework through the exclusive use of gluon fusion processes.
