TL;DR: In this paper, the authors calculated the next-to-leading order (NLO) new physics contributions to the mass splitting and the branching ratio induced by the charged Higgs loop diagrams in the third type of two-Higgs-doublet models (model III) and drew the constraints on the free parameters of model III.

Charm multiplicity and the branching ratios of inclusive charmless b quark decays in the general two Higgs doublet models
TL;DR: In this article, the branching ratios of various inclusive charmless b decays were calculated by using the low energy effective Hamiltonian including next-to-leading order QCD corrections, and examined the current status and new physics effects on the determination of the charm multiplicity $n_c$ and semileptonic branching ratio $B_{SL}.

CP Violation in the Renormalizable Theory of Weak Interaction
TL;DR: In this article, it was shown that no CP-violating interactions exist in the quartet scheme without introducing any other new fields, and that the strong interaction must be chiral SU ( 4) X SU( 4) invariant as precisely as the conservation of the third component of the iso-spin.

TL;DR: In this paper, the authors review the present status of QCD corrections to weak decays beyond the leading-logarithmic approximation, including particle-antiparticle mixing and rare and $\mathrm{CP}$-violating decays.

Review of particle physics. Particle Data Group
TL;DR: The Particle Data Group's biennial review as mentioned in this paper summarizes much of Particle Physics, using data from previous editions, plus 1600 new measurements from 550 papers, and lists, evaluates and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons.

Dynamics of Spontaneous Symmetry Breaking in the Weinberg-Salam Theory
TL;DR: In this article, the existence of fundamental scalar fields constitutes a serious flaw of the Weinberg-Salam theory and a possible scheme without such fields is described, where the symmetry breaking is induced by a new strongly interacting sector whose natural scale is of the order of a few TeV.

Natural conservation laws for neutral currents
TL;DR: In this paper, the authors explore the consequences of the assumption that the direct and induced weak neutral currents in an SU(2) gauge theory conserve all quark flavors naturally, i.e., for all values of the parameters of the theory.
