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…
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…
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 …
