Beyond the Standard Model Higgs bosons in the reach of the LHC — •Thomas Biekoetter¹, Alexander Grohsjean¹, Sven Heinemeyer², Victor Lozano¹, Christian Schwanenberger¹, and Georg Weiglein¹ — ¹DESY, Hamburg, Germany — ²IFT, Madrid, Spain

Many extensions of the Standard Model (SM) contain additional Higgs bosons heavier than the Higgs boson at 125GeV. However, there is also the possibility of beyond the SM (BSM) Higgs bosons with masses below 125 GeV. In both cases there is room left for a discovery during the upcoming (HL)-LHC runs. Moreover, it is an interesting question whether there are hints for such BSM Higgs bosons already in the currently existing data. We interpret different collider excesses below the TeV scale in terms of scalar and pseudoscalar resonances in the N2HDM and the the NMSSM. We demonstrate for both models which of the excesses can be realized simultaneously, while still accommodating a SM-like Higgs boson at 125GeV and being in agreement with the other relevant theoretical and experimental constraints. We finally discuss how the scenarios can be probed in the near future.
