abstract

We compute fermion pair production cross sections in $e^+e^-$ annihilation in models of electroweak symmetry breaking in warped 5-dimensional space. Our analysis is based on a framework with no elementary scalars, only gauge bosons and fermions in the bulk. We apply a novel Green's function method to obtain an analytic understanding of the new physics effects across the parameter space. We present results for $e^+e^-\to b\bar b$ and $e^+e^-\to t\bar t$. The predicted effects will be visible in precision measurements. Different models of $b$ quark mass generation can be distinguished by these measurements already at 250 GeV in the center of mass.

    In the SO(5) x U(1) x SU(3) gauge-Higgs unification model on RS space, total anomalies including all KK fermion modes are universal and independent of bulk masses, expressed via brane wave functions, allowing per-gene...

    hep-ph 2019-08 conditional novelty 6.0 of 10

    In the SO(5) x U(1) x SU(3) gauge-Higgs unification model, gauge-invariant brane couplings can generate an approximately correct CKM matrix while suppressing FCNCs below 10^-6 of the weak interactions, at the cost of ...

  3. Tests of the Standard Model at the International Linear Collider

    hep-ex 2019-08 conditional novelty 5.0 of 10

    The paper projects that a polarized e+e- collider at 250 GeV to 1 TeV would measure most Higgs couplings to sub-percent precision and improve many electroweak observables by an order of magnitude.
