21. A Flavour of Grand Unified Composite Higgs

Matthew Starbuck (University of Sussex)

15/12/2023, 11:00

Long Talk (20 mins)

Composite Higgs models present an elegant solution to the naturalness issue associated with the Higgs mass. Furthermore, due to the supposition of new physics at the TeV scale, the flavour physics associated with these models must be non-generic in order to pass tight experimental constraints. This talk presents research into extending a composite Higgs model based off an $SO\left(11\right) /...

6. Combating gravity gradient noise in atom interferometer searches for ultra-light dark matter

John Carlton (King's College London)

Long Talk (20 mins)

Several upcoming experiments propose using new quantum sensing technology, long-baseline atom interferometers (AIs), to search for new fundamental physics including gravitational waves and ultra-light dark matter (ULDM). Previous studies have shown the sensitivity of AIs to scalar ULDM, but there are higher-spin bosonic candidates that these experiments could be sensitive to including vector...
