Fermion Geometry and the Renormalization of the Standard Model Effective Field Theory
Benoît Assi, Andreas Helset, Aneesh V. Manohar +2
The geometry of field space governs on-shell scattering amplitudes. We formulate a geometric description of effective field theories which extends previous results for scalars and…
Non-renormalization Theorems without Supersymmetry
Clifford Cheung, Chia-Hsien Shen
We derive a new class of one-loop non-renormalization theorems that strongly constrain the running of higher dimension operators in a general four-dimensional quantum field theory.…
Computing decay rates for new physics theories with FeynRules and MadGraph5/aMC@NLO
Johan Alwall, Claude Duhr, Benjamin Fuks +3
We present new features of the FeynRules and MadGraph5/aMC@NLO programs for the automatic computation of decay widths that consistently include channels of arbitrary final-state mu…
Long-Distance Contribution to ΔΓs/Γs of the System
Chun-Khiang Chua, Wei-Shu Hou, Chia-Hsien Shen
We estimate the long-distance contribution to the ΔΓs of B_s system, based mainly on two-body D^(*)_s\Dbar^(*)_s modes and three-body D^(*)_s\Dbar^(*)\Kbar^(*) modes (and their CP…
Leading Effect of CP Violation with Four Generations
Wei-Shu Hou, Yao-Yuan Mao, Chia-Hsien Shen
In the Standard Model with a fourth generation of quarks, we study the relation between the Jarlskog invariants and the triangle areas in the 4-by-4 CKM matrix. To identify the lea…
