14. Stau Searches at the ILC

María Teresa Núñez Pardo de Vera (DESY)

28/02/2022, 15:00

"The direct pair-production of the tau-lepton superpartner, stau, is one
of the most interesting channels to search for SUSY. First of all the stau is
with high probability the lightest of the scalar leptons. Secondly the
signature of stau pair production signal events is one of the most difficult
ones, yielding to the 'worst' and so most global scenario for the searches.
The current...

6. Dark matter production with light mediator exchange at future e+e- colliders

Aleksander Filip Zarnecki (University of Warsaw)

One of the primary goals of the proposed future collider experiments is to search for dark matter (DM) particles using different experimental approaches. High energy e+e- colliders offer unique possibility for the most general search based on the mono-photon signature. As any e+e- scattering process can be accompanied by a hard photon emission from the initial state radiation, analysis of the...

9. Measuring neutrino dynamics via light higgsinos and sneutrinos

Harri Waltari (University of Uppsala)

Supersymmetry offers a portal to study neutrino physics via sneutrinos. I shall discuss a signature that can be only detected at an electron-positron collider, namely the production of a charged higgsino pair, one of them subsequently decaying to a charged lepton and a right-sneutrino LSP. This decay is rare, with a branching ratio O(10^-5) and hence the clean environment and fixed partonic...

4. Heavy Neutrinos at Future Linear e+e- Colliders

Krzysztof Mekala

Neutrinos are probably the most mysterious particles of the Standard Model. The mass hierarchy and oscillations, as well as the nature of their antiparticles, are currently being studied in experiments around the world. Moreover, in many models of New Physics, baryon asymmetry or dark matter density in the universe are explained by introducing new species of neutrinos. Among others, heavy...

21. Sensitivity for Long-Lived particles at FCC-ee

Juliette Alimena (CERN)

20. Sensitivity to Decays of Long-Lived Dark Photons at the ILC

8. Low mass scalars at e+e- colliders

Tania Natalie Robens (Rudjer Boskovic Institute (HR))

02/03/2022, 15:40

I report on studies and possible BSM scenarios with (Higgs) scalars of masses < 125 GeV. This talk is based on similar overview talks at the CEPC/ FCC workshops within the last half year, and is tailored be used as a foundation for a Snowmass White Paper on this topic.

11. Phenomenology of dark matter in complex scalar singlet extensions of Two Higgs doublet models

Juhi Dutta

02/03/2022, 16:00

Extensions of the two Higgs doublet models with a singlet scalar can easily accommodate all current experimental constraints and are highly motivated candidates for Beyond Standard Model Physics. It can successfully provide a dark matter candidate, explain baryogenesis and provide gravitational wave signals. In this work, we focus on the dark matter phenomenology of the two Higgs doublet model...
