Abstract
The known isospin-breaking contributions to the K → ππ amplitudes are reanalyzed, taking into account our current understanding of the quark masses and the relevant non-perturbative inputs.…
Nonleptonic $K\to 2\,\pi$ decay dynamics

Hadronic τ Decays as New Physics Probes in the LHC Era.
- PhysicsPhysical review letters

It is found that the ratios of nonstandard couplings to the Fermi constant are bound at the subpercent level, which puts tighter constraints on lepton universality violation in the gauge boson-lepton vertex corrections.
Updated determination of chiral couplings and vacuum condensates from hadronic $\tau$ decay data

The mass of the strange quark is determined from SU(3)-breaking effects in the τ hadronic width. Compared to previous analyses, the contributions from scalar and pseudoscalar spectral functions,…
Predicting the τ strange branching ratios and implications for Vus

A bstractHadronic τ decays provide several ways to extract the Cabbibo-Kobashi-Maskawa (CKM) matrix element Vus. The most precise determination involves using inclusive τ decays and requires as input…
Update of the ALEPH non-strange spectral functions from hadronic $$\tau $$τ decays

A comprehensive overview of kaon decays is presented. The Standard Model predictions are discussed in detail, covering both the underlying short-distance electroweak dynamics and the important…
Weak decays beyond leading logarithms

We review the present status of QCD corrections to weak decays beyond the leading logarithmic approximation including particle-antiparti cle mixing and rare and CP violating decays. After presenting…
Operator product expansion, heavy quarks, QCD duality and its violations
- Physics
