Anomalies in global SMEFT analyses. A case study of first-row CKM unitarity

Journal of High Energy Physics
Recent developments in the Standard Model analysis of semileptonic charged-current processes involving light quarks have revealed ~ 3σ tensions in Cabibbo universality tests involving meson, neutron, and nuclear beta decays.

Constraints on a generalization of geometric quantum mechanics from neutrino and B 0- B 0 ¯ $$ \overline{B^0} $$ oscillations

Journal of High Energy Physics
Nambu Quantum Mechanics, proposed in Phys. Lett. B536, 305 (2002), is a deformation of canonical Quantum Mechanics in which the manifold over which the “phase” of an energy eigenstate time evolves is modified.

CKM fits as of winter 2009 and sensitivity to New Physics

, 2009
International audienceWe present the status of the CKM matrix parameters in the framework of the Standard Model. We perform a model independent analysis to set constraints on additional effective parameters accounting for possible New Physics effects and

CKM matrix and fermion masses in the dualized standard model [PDF]

, 1997
A Dualized Standard Model recently proposed affords a natural explanation for the existence of Higgs fields and of exactly 3 generations of fermions, while giving at the same time the observed fermion mass hierarchy together with a tree-level CKM matrix ...

mixing and the CKM parameters (ϱ, η) from the Laplace sum rules [PDF]

Physics Letters B, 1995
Abstract Using the Laplace sum rule (LSR) approach, which is less affected by the contribution of the higher mass hadronic states than the Finite Energy Sum Rule (FESR), we test the reliability of the existing estimate of the K 0 - K 0 mixing parameter from the four-quark two-point correlator.

The q 2 moments in inclusive semileptonic B decays

Journal of High Energy Physics
We compute the first moments of the q 2 distribution in inclusive semileptonic B decays as functions of the lower cut on q 2, confirming a number of results given in the literature and adding the O α s 2 β 0 $$ O\left({\alpha}_s^2{\beta}_0\right) $$ BLM ...
