We study the neutrino-associated Zh production process at lepton colliders, whose cross section exceeds that of Zh production in the multi-TeV energy regime. The scattering amplitudes are classified into three main groups according to the topology of the corresponding Feynman diagrams, and their interference patterns are systematically analyzed. We demonstrate that the delicate gauge...
In this talk, I will discuss novel strategies to search for long-lived scalars at future lepton colliders in the context of the Type-II seesaw model. In the low-mass range, and for an appropriate choice of the triplet vev, these scalars can become long-lived, leading to displaced-vertex signatures. Depending on the proposed center-of-mass energy, we consider the pair production of these...
We study the CP-even neutral Higgs boson decays $h^0 \to c \bar{c}, b\bar{b}, b \bar{s}, \gamma \gamma, g g$ in the Minimal Supersymmetric Standard Model (MSSM) with general quark flavor violation (QFV) due to squark generation mixings, identifying the $h^0$ as the Higgs boson with a mass of 125 GeV. We compute the widths of the $h^0$ decays to $c \bar c, b \bar b, b \bar s$ at full one-loop...
