The Very Nearly Right Theory of Flavor
Nima Arkani-Hamed, Carolina Figueiredo, Lawrence J. Hall +1
The paper proposes a simple class of Yukawa matrix textures with nine non‑zero entries that naturally link the observed CKM unitarity‑triangle angles to multiples of π/8, offering…
Anomalies in Hadronic Decays
Bhubanjyoti Bhattacharya, Marianne Bouchard, Alexandre Jean +2
The authors extend a flavor‑SU(3) analysis of charmless B meson decays to vector‑vector final states and find statistically significant deviations from Standard Model expectations,…
From Yukawa Couplings to Flavor Observables: A Top-Down, Analytically Solvable Geometric Framework for CKM/PMNS Mixing and CP Violatio
Chilong Lin
The paper introduces a geometric framework that uses two-dimensional ratio vectors to parametrize the CKM matrix, reducing the number of independent parameters and linking the stru…
in the from Supersymmetric Standard Model
Xiao-Jie Hu, Hai-Bin Zhang, Tai-Fu Feng
The paper studies the rare inclusive decay B→Xₛℓ⁺ℓ⁻ within the μ-from-ν Supersymmetric Standard Model, calculating the relevant Wilson coefficients, scanning the model’s parameter…
Observation of violation in decays
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1172
The LHCb collaboration measures the time‑dependent CP asymmetry in B⁰ → J/ψ ρ⁰ decays, reporting the first observation of CP violation in this channel and determining the effective…
Constraints on lepton-flavor mixing with third-generation new physics
Sebastiano Covone, Pol Morell, Arianna Tinari
The paper investigates how an approximate U(2)^5 flavor symmetry with new physics mainly coupled to third‑generation fermions constrains mixing between second‑ and third‑generation…
