Unraveling Sum Rules in 2HDM - Beyond Standard Model Implications — •Sara Chopra1, Saurav Bania1, Gudrid Moortgart Pick1, and Sven Heinemeyer2 — 1Universität Hamburg — 2Consejo Superior de Investigaciones Científicas (CSIC)
Within this work, we investigate the implications of sum rules within the Two Higgs Doublet Model (2HDM). These are derived by obtaining the possible couplings from the 2HDM Lagrangian and relating them to the corresponding Standard Model (SM) couplings. We also studied the vector-boson and fermion scatterings, at high-energies. We investigate whether the E2 and E4 dependencies are cancelled out using our sum rule constraints, ensuring that unitarity is preserved.
We also investigate the Mass limits on the 2HDM Higgs boson. We will also take into account the latest experimental data (Higgs-boson rate measurements and Higgs-boson searches) in our research.
