Top and Beauty synergies in SMEFT-fits at present and future colliders
Stefan Bißmann, Cornelius Grunwald, Gudrun Hiller +1
We perform global fits within Standard Model Effective Field Theory (SMEFT) combining top-quark pair production processes and decay with flavor changing neutral cu…
Multi-lepton signatures of vector-like leptons with flavor
Stefan Bißmann, Gudrun Hiller, Clara Hormigos-Feliu +1
We investigate collider signatures of standard model extensions featuring vector-like leptons and a flavorful scalar sector. Such a framework arises naturally within asymptotically…
Rare charm dineutrino null tests for -machines
Rigo Bause, Hector Gisbert, Marcel Golz +1
Rare transitions into dineutrinos are strongly GIM-suppressed and constitute excellent null tests of the standard model. While branching ratios of …
Radiative three-body D-meson decays in and beyond the standard model
Nico Adolph, Joachim Brod, Gudrun Hiller
We study radiative charm decays , in QCD factorization at leading order and within heavy hadron chiral perturbation theory. Branching ratios includin…
Model Building from Asymptotic Safety with Higgs and Flavor Portals
Gudrun Hiller, Clara Hormigos-Feliu, Daniel F. Litim +1
We perform a comprehensive search for Standard Model extensions inspired by asymptotic safety. Our models feature a singlet matrix scalar field, three generations of vector-like le…
Lepton universality and lepton flavor conservation tests with dineutrino modes
Rigo Bause, Hector Gisbert, Marcel Golz +1
-invariance links charged dilepton and dineutrino couplings. Phenomenological implications are worked out for flavor changing neutral currents involving strange, charm, be…
