Springer: Search for heavy resonances decaying into a $ W $ or $ Z $ boson and a Higgs boson in final states with leptons and $ b $-jets in 36 fb $^{-1} $ of $\sqrt s= 13$ TeV …

Abstract:

The ATLAS [1] and the CMS [2] collaborations discovered a Higgs boson (h) with a mass near 125 GeV and properties consistent with the Standard Model (SM) pbkp_redictions [3–5]. Two of the most important questions that remain are how the Higgs boson mass is protected against large radiative corrections (the naturalness problem [6–8]) and whether the Higgs boson is part of an extended scalar sector [9], thus making this particle important for searches for new physics beyond the SM. Various models with dynamical electroweak symmetry breaking scenarios attempt to solve the naturalness problem by assuming a new strong interaction at a higher energy scale. These models generically pbkp_redict the existence of new vector resonances that naturally decay into a vector boson and a Higgs boson, for example in Minimal Walking Technicolour [10–12], Little Higgs [13], and composite Higgs models [14, 15]. The decays into a vector-boson and Higgs boson final state are frequently enhanced in these models.
