Searches for resonances decaying to boson pairs in ATLAS / Bellos, Panagiotis (University of Birmingham (GB))
Many new physics models predict the existence of new particles decaying into two bosons ($W$, $Z$, photons, or Higgs bosons) making these important signatures in the search for new physics. [...]

Tests of neutrino mass models with the ATLAS detector / Novak, Tadej (Deutsches Elektronen-Synchrotron (DE))
Multiple theories beyond the Standard Model predict the existence of heavy neutrinos, such as the Type I or Type III seesaw mechanisms that can explain the light neutrino masses, or left-right symmetric models that restore parity symmetry in weak interactions at a higher energy scale and predict right-handed counterparts to the weak gauge bosons.
