This topical group aims to study the sensitivity of Beyond Standard Model (BSM) phenomena for future experiments in the energy frontier. Particular emphasis is given to signatures that appear in a large variety of BSM extensions.

This TWiki page collects useful information on organization, topics, and technical details, as we see useful for the community. Please check for updates often and subscribe to our mailing list (see above) to be kept updated.

An initial list of topics to be covered by this topical group are:

• New Fermions, e.g., Top partners, Excited Quarks/Leptons, Sterile Neutrinos
• New Bosons, e.g., W', Z', diboson-resonances
• Dark/Hidden sectors, e.g., ALP, dark photons
• Long-live particle signatures
• BSM interplay with EFT

The list above is not meant to be a comprehensive list, but rather a starting point. Please do not hesitate to contact us with more ideas and studies. We welcome expressions of interest submitted via a form: https://forms.gle/1freqMHfTjAobga86 .

An evolving list of active proposals that proponents have agreed to share is available here.

Synergies with other topical groups and frontiers are highly anticipated. All groups commit to working together to ensure the least possible duplication and a full sharing of information. Notable examples of cross-group topics mainly discussed by other topical groups but very relevant for this topical group as well include:

• mono-X searches (EF10 - BSM: Dark Matter at colliders)
• EFT analyses of EWK observables (EF04 - EW Precision Physics and constraining new physics)
• Heavy Higgs searches and exotic Higgs decays (EF02 - EW Physics: Higgs Boson as a portal to new physics)
• Model-specific searches for excited fermions (EF08 - BSM: Model specific explorations)

Similarly, a variety of topics covered by this topical group are relevant to many other groups, and conveners are here to ensure and help in the cross-communication.
