Electroweak precision observables at NLL order in the SMEFT
Ulrich A. Haisch, Ben A. Stefanek
Electroweak precision observables (EWPO) remain among the most powerful indirect probes of physics beyond the Standard Model (BSM), and future colliders are expected to s…
Minimal Flavor Protection for TeV-scale New Physics
Admir Greljo, Ajdin Palavrić, Ben A. Stefanek
We determine how much TeV-scale new physics can deviate from flavor universality, , while respecting stringent bounds on flavor-changing neutral currents. The minimal conti…
Cornering Natural SUSY at a Tera- Factory
Admir Greljo, Ben A. Stefanek, Alessandro Valenti
The future circular collider (FCC-ee) stands out as the next flagship project in particle physics, dedicated to uncovering the microscopic origin of the Higgs boson. In t…
The Higgs Self-Coupling at FCC-ee
Victor Maura, Ben A. Stefanek, Tevong You
Single Higgs production at FCC-ee probes the Higgs self-coupling at next-to-leading order (NLO). Extracting a bound requires a global analysis accounting for other possible new phy…
Accuracy complements energy: electroweak precision tests at Tera-Z
Victor Maura, Ben A. Stefanek, Tevong You
A Tera- factory, such as FCC-ee or CEPC, will have indirect sensitivity to heavy new physics up to the tens of TeV scale through higher-order loop contributions to precision mea…
Non-universal probes of composite Higgs models: New bounds and prospects for FCC-ee
Ben A. Stefanek
We study the leading loop-level phenomenology of composite Higgs models via the effective field theory of a strongly interacting light Higgs and top quark (SILH+TQ). We systematica…
