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…
Kaon physics in the SMEFT
Jason Aebischer
Kaon physics observables are highly sensitive to New Physics (NP) effects and form in combination with the Standard Model Effective Field Theory (SMEFT) a powerful tool to study ph…
Anomalous Dimension of a General Effective Gauge Theory II: Fermionic Sector
Jason Aebischer, Luigi C. Bresciani, Nudzeim Selimovic
The complete set of one-loop anomalous dimensions for general Effective Field Theories (EFTs) is derived using on-shell methods. Combined with previous findings for the bosonic sec…
SMEFT ATLAS: The Landscape Beyond the Standard Model
Jason Aebischer, Andrzej J. Buras, Jacky Kumar
The Standard Model Effective Field Theory (SMEFT) based on the unbroken gauge group and containing only particles of the S…
Time-Dependent Precision Measurement of Decay at FCC-
Tsz Hong Kwok, Zachary Polonsky, Valeriia Lukashenko +2
We study the feasibility of measuring time-dependent violation in the rare flavor-changing neutral current (FCNC) decay at…
Kaon Physics: A Cornerstone for Future Discoveries
Jason Aebischer, Atakan Tugberk Akmete, Riccardo Aliberti +153
The kaon physics programme, long heralded as a cutting-edge frontier by the European Strategy for Particle Physics, continues to stand at the intersection of discovery and innovati…
Anomalous Dimension of a General Effective Gauge Theory I: Bosonic Sector
Jason Aebischer, Luigi C. Bresciani, Nudzeim Selimovic
We classify the physical operators of the most general bosonic effective gauge theory up to dimension six using on-shell methods. Based on this classification, we compute the compl…
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…
wilson: A package for renormalization group running in the SMEFT with Sterile Neutrinos
Jason Aebischer, Tejhas Kapoor, Jacky Kumar
Sterile neutrinos are well-motivated beyond the Standard Model (BSM) particles. The Standard Model Effective Field Theory (SMEFT) augmented with these new fields is known as the $ν…
Fierz identities at the one-loop level
Jason Aebischer
One-loop Fierz identities are discussed, together with general basis transformations in Effective Field theories at the tree- and one-loop level. To this end, the notion of one-loo…
