Flavour and LHC constraints in the 2HDM — Oliver Atkinson1, •Matthew Black2, Christoph Englert1, Alexander Lenz2, Aleksey Rusov2, and James Wynne3 — 1SUPA, School of Physics and Astronomy, University of Glasgow, Glasgow, UK — 2Physik Department, Universität Siegen, Walter-Flex-Str. 3, Siegen, Germany — 3IPPP, Department of Physics, University of Durham, UK
We present comprehensive studies of the Two Higgs Doublet Model with Type I and Type II Yukawa couplings. To find bounds on the mass spectrum of these models, contributions to flavour, Higgs, and electroweak observables from the new scalars and couplings are considered, using theoretical constraints to inform these fits. We compare the results of these fits to those from direct searches at the LHC, finding regions of parameter space allowed by both flavour and collider. In addition, we test the consequences of our results on electroweak baryogenesis and the possibility of generating a strong first order phase transition in the 2HDM.
