Several models of grand unification predict the existence of an additional gauged $U(1)_D$ symmetry, which gives rise to a new heavy neutral gauge boson $Z'$ at the TeV scale. In general, the Standard Model particles may be charged under this new symmetry, with gauge coupling $g_D$, and the $Z'$ can exhibit a kinetic mixing $\epsilon$ with the hypercharge gauge boson as well. Future...

4. Exotic h → Za Higgs decays into τ leptons

Camila Ramos

Exotic Higgs decays are among the most promising areas to be explored at the High-Luminosity LHC, given the unprecedentedly large amount $(\sim 3 \times 10^8)$ of 125 GeV Higgs bosons that will be produced. In this context, we propose a new search channel for which the Higgs boson decays to a (leptonically decaying) $Z$ boson and a light BSM pseudoscalar $a$, which subsequently decays to a...
