Ratios of exclusive to inclusive b to s lepton lepton observables discriminate between new physics and constant hadronic effects, with current data favoring new physics.
Doubly charmed baryon decays provide symmetry-protected null tests for nonfactorizable QCD and lepton-universality ratios sensitive to new physics at multi-TeV scales.
Updated lifetime predictions for doubly heavy baryons and B_c meson with NNLO and NLO corrections in MS-bar, kinetic, and Upsilon mass schemes, including new hierarchies for bc states.
In minimal benchmarks with a vector-like down quark D and singlet scalar, the new-physics contribution to B to X_s gamma is only 0.4 percent of the Standard Model value at TeV scales, while B_s mixing imposes stronger limits on the complex-scalar case.
The CP-violating decay-rate asymmetry in Σ⁺→pℓ⁺ℓ⁻ is allowed to reach tens of percent and is testable at LHCb.
A data-driven SU(3)-breaking analysis of B to PP decays yields QCD-factorization amplitudes that resemble dynamical predictions and require no enhanced annihilation terms.
Lifetimes of Xi_cc++, Xi_cc+, Omega_cc+ are (2.67 ± 0.94, 0.47 ± 0.08, 1.79 ± 0.62) × 10^{-13} s and for Xi_bb0, Xi_bb-, Omega_bb- are (0.75 ± 0.11, 0.92 ± 0.15, 0.93 ± 0.15) × 10^{-12} s, with W-exchange driving large splittings in the charmed sector.
Perturbative symmetry-breaking corrections shift the branching ratio and normal lepton polarization asymmetry by ~3% in B → K0*(1430) μ+μ−, so larger experimental deviations would indicate new physics.
CP asymmetries for B+ to pi+ pi0, D+ to pi+ pi0, and K+ to pi+ pi0 are estimated in the Standard Model at roughly 3 times 10 to the -3, 10 to the -5, and 10 to the -6 using a unified formalism for isospin violation.
The Left-Right Inverse Seesaw model generates a non-decoupling scalar operator that enhances the differential forward-backward CP asymmetry A_CP^FB(s) near K* and K0* resonances in τ → Kπν_τ while leaving the integrated asymmetry too small to explain the BaBar result.
The work computes differential and total branching ratios plus forward-backward asymmetries for Λ_b → Λ ℓ⁺ℓ⁻, Σ_b → Σ ℓ⁺ℓ⁻ and Ξ_b → Ξ ℓ⁺ℓ⁻ in 2HDM Type III and contrasts them with SM predictions.
