In recent years, theoretical and phenomenological studies with effective field theories have become a trending and prolific line of research in the field of high-energy physics. In order to discuss present and future prospects concerning automated tools in this field, the SMEFT-Tools 2022 workshop was held at the University of Zurich from 14th-16th September 2022. [...]

Higgs-Mediated B0s,dμτ,eτ and τ3μ,eμμ Decays in Supersymmetric Seesaw Models / Dedes, Athanasios (Bonn U.) ; Ellis, John R. (CERN) ; Raidal, Martti (CERN ; NICPB, Tallinn)
We study the rates allowed for the Higgs-mediated decays B0s,dμτ,eτ and τμμμ,eμμ in supersymmetric seesaw models, assuming that the only source of lepton flavour violation (LFV) is the renormalization of soft supersymmetry-breaking terms due to off-diagonal singlet-neutrino Yukawa interactions. These decays are strongly correlated with, and constrained by, the branching ratios for B0s,dμμ and τμ(e)γ. Parametrizing the singlet-neutrino Yukawa couplings Yν and masses MNi in terms of low-energy neutrino data, and allowing the flavour-universal soft masses for sleptons and for squarks, as well as those for the two Higgs doublets, to be different at the unification scale, we scan systematically over the model parameter space.

D-term Spectroscopy in Realistic Heterotic-String Models / Dedes, Athanasios (Rutherford) ; Faraggi, Alon E. (Minnesota U. ; CERN)
The emergence of free fermionic string models with solely the MSSM charged spectrum below the string scale provides further evidence to the assertion that the true string vacuum is connected to the Z_2 x Z_2 orbifold in the vicinity of the free fermionic point in the Narain moduli space. An important property of the Z_2 x Z_2 orbifold is the cyclic permutation symmetry between the three twisted sectors. [...]
