We systematically study potential effects of BSM physics in the e+ e- -> Z H process. To this end, we include all relevant dimension-6 Standard Model Effective Field Theory operators and work to next-to-leading order (NLO) accuracy in the electro-weak coupling. We consider both polarized and unpolarized electron and positron beams and present results for $\sqrt{s}=240, 365 and 500~GeV and...

With the current precision of measurements by ATLAS and CMS experiments, it cannot be excluded that a SM-like Higgs boson is a CP violating mixture of CP-even and CP-odd states. We explore this possibility here, assuming Higgs boson production in ZZ-fusion, at 1 TeV ILC, with unpolarized beams. The full reconstruction of SM background and fast reconstruction of the signal is performed,...

We study a CP-violating top Yukawa coupling at muon collider through $\mu^-\mu^+\to t\bar{t}h\nu\bar{\nu}$ process. The gauge invariant Lagrangian is obtained by a dimension-6 operator. Although the cross section and distributions are gauge invariant, amplitudes calculated in the Feynman Diagram (FD) gauge allow us to understand the origin of the energy and angular dependence of CP violating...

The European Strategy for Particle Physics identifies an e+e- Higgs factory as its top priority and the first step towards an ultra-high energy future hadron collider. The Future Circular Collider (FCC) is being proposed at CERN to address these goals. The FCC includes an electron-positron collider (FCC-ee), which will be followed by an energy-frontier hadron collider (FCC-hh).

The Higgs portal to BSM is very well motivated both theoretically and experimentally. We study long-lived BSM particles in the Higgs portal model, produced either from the decay of a B-meson or the Higgs boson. We discuss the search for these particles at future colliders, like the 100 TeV future collider experiment. Given the need to optimise the designs of dedicated LLP detectors for future...
