 Search for direct production of electroweakinos in final states with one lepton, missing transverse momentum and a Higgs boson decaying into two $b$-jets in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector The results of a search for electroweakino pair production $pp \rightarrow \tilde\chi^\pm_1 \tilde\chi^0_2$ in which the chargino ($\tilde\chi^\pm_1$) decays into a $W$ boson and the lightest neutralino ($\tilde\chi^0_1$), while the heavier neutralino ($\tilde\chi^0_2$) decays into the Standard Model 125 GeV Higgs boson and a second $\tilde\chi^0_1$ are presented.

 CP-violating Higgs-gauge boson couplings in $H\nu \bar{\nu}$ production at three energy stages of CLIC / Karadeniz, Ozgun (Bolu Abant Izzet Baysal University) ; Senol, Abdulkadir (Abant Izzet Baysal University (TR)) ; Oyulmaz, Kaan Yuksel (Abant Izzet Baysal University (TR)) ; Denizli, Haluk (Ankara University Institute of Accelerator Technologies (TR)) A phenomenological study of CP-violating dimension-six operators via the $e^+e^−$ → $\nu \bar{\nu} H$ process is performed in a model-independent Standard Model effective field theory framework at all energy stages of CLIC using the updated baseline integrated luminosities. All signal and relevant background events are generated in MadGraph5_aMC@NLO and passed through PYTHIA 8 for parton showering and hadronization at parton level.
