1. A global likelihood for precision constraints and flavour anomalies / Aebischer, Jason ; Kumar, Jacky ; Stangl, Peter ; Straub, David M.
We present a global likelihood function in the space of dimension-six Wilson coefficients in the Standard Model Effective Field Theory. [...]

2. Flavor physics and flavor anomalies in minimal fundamental partial compositeness / Sannino, Francesco ; Stangl, Peter ; Straub, David M. ; Thomsen, Anders Eller
Partial compositeness is a key ingredient of models where the electroweak symmetry is broken by a composite Higgs state. [...]

3. Status of the B→K∗μ+μ- anomaly after Moriond 2017 / Altmannshofer, Wolfgang ; Niehoff, Christoph ; Stangl, Peter ; Straub, David M.
Motivated by recent results by the ATLAS and CMS collaborations on the angular distribution of the B→K∗μ+μ- decay, we perform a state-of-the-art analysis of rare B meson decays based on the b→sμμ transition. [...]

4. Electroweak symmetry breaking and collider signatures in the next-to-minimal composite Higgs model / Niehoff, Christoph ; Stangl, Peter ; Straub, David
We conduct a detailed numerical analysis of the composite pseudo-Nambu-Goldstone Higgs model based on the next-to-minimal coset SO(6)/SO(5) ≅ SU(4)/Sp(4), featuring an additional SM singlet scalar in the spectrum, which we allow to mix with the Higgs boson. [...]

5. Direct and indirect signals of natural composite Higgs models / Niehoff, Christoph ; Stangl, Peter ; Straub, David
We present a comprehensive numerical analysis of a four-dimensional model with the Higgs as a composite pseudo-Nambu-Goldstone boson that features a calculable Higgs potential and protective custodial and flavour symmetries to reduce electroweak fine-tuning. [...]

6. Violation of lepton flavour universality in composite Higgs models / Niehoff, Christoph ; Stangl, Peter ; Straub, David M.
We investigate whether the 2.6 σ deviation from lepton flavour universality in B+→K+ℓ+ℓ− decays recently observed at the LHCb experiment can be explained in minimal composite Higgs models. [...]
