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…
The art of simulating the early Universe. Part II. Non-canonical cases & gravitational waves
Jorge Baeza-Ballesteros, Daniel G. Figueroa, Adrien Florio +7
We present a discussion on lattice techniques for the simulation of non-canonical field theory circumstances, complementing our previous monograph (arXiv:2006.15122) on canonical c…
Minimal Flavor Protection for TeV-scale New Physics
Admir Greljo, Ajdin PalavriÄ, 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…
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…
Third-Family Quark-Lepton Unification and Electroweak Precision Tests
Lukas Allwicher, Gino Isidori, Javier M. Lizana +2
We analyze the compatibility of the hypothesis of third-family quark-lepton unification at the TeV scale with electroweak precision data, lepton flavor universality tests, and high…
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…
