Description

We explore 2 Higgs Doublet models with non-standard flavor structures. In analogy to the four,
well studied models with natural flavor conservation (type 1, type 2, lepton-specific, flipped), we
identify four models that preserve an approximate SU (2) 5 flavor symmetry acting on the first two
generations. In all four models, the couplings of the 125 GeV Higgs are modified in characteristic
flavor non-universal ways. Also the heavy neutral and charged Higgs bosons show an interesting
non-standard phenomenology. We discuss their production and decay modes and identify the most
sensitive search channels at the LHC. We also study the effects on low energy flavor violating
processes. We find relevant constraints from B s meson oscillations and from the rare decay
B s →μ + μ − . Lepton flavor violating B meson decays like B s → τ μ and B → K (∗) τ μ can have branching ratios at an observable level.
