Universal Two-Loop Current--Current Renormalization of Four-Fermion Operators
Jason Aebischer, Sudeepan Datta, Pol Morell +2
The complete one- and two-loop gauge and scalar current--current contributions to the running of arbitrary dimension-six four-fermion operators are reported. The results are obtain…
The structure of multi-axion solutions to the strong CP problem
Mario Fernández Navarro, Marta F. Zamoro, Marko Pesut +1
A broad experimental program is targeting the QCD axion band predicted by single-axion solutions to the strong CP problem. Multi-axion theories provide a well-motivated departure f…
Cosmological History of Flavour Deconstruction Models: Constraints from Monopole Production
Marko Pesut, Davide Racco, Yunlong Zhao
We highlight a generic connection between extensions of the Standard Model featuring low-scale semi-simple embeddings of and the phenomenology of magnetic mono…
Two-Loop Anomalous Dimensions in the LEFT: Dimension-Six Four-Fermion Operators in NDR
Jason Aebischer, Pol Morell, Marko Pesut +1
We derive the complete set of two-loop anomalous dimensions describing the mixing of four-fermion operators in the Low Energy Effective Field Theory (LEFT). The calculation is perf…
Flavored Circular Collider: cornering New Physics at FCC-ee via flavor-changing processes
Lukas Allwicher, Gino Isidori, Marko Pesut
We illustrate the potential of a future high-intensity collider running at the pole in probing extensions of the Standard Model via precise measurements of flavor-cha…
Flavour Deconstructing the Composite Higgs
Sebastiano Covone, Joe Davighi, Gino Isidori +1
We present a flavour non-universal extension of the Standard Model combined with the idea of Higgs compositeness. At the TeV scale, the gauge groups and are…
