Spectral Functions from Hadronic τ Decays and QCD
Hadronic decays of the τ lepton provide a clean environment to study hadron dynamics in an energy regime dominated by resonances, with the interesting information captured in the spectral functions. Recent results from ALEPH on exclusive channels are presented, with some emphasis on the ππ final state which plays a crucial role for the determination of the hadronic contribution to the muon anom...
متن کاملQCD Analysis of Hadronic τ Decays Revisited
The calculation of perturbative corrections to the spectral moments observable in hadronic τ decays is reconsidered. The exact order-αs results and the resummation procedure of Le Diberder and Pich are compared with a partial resummation of the perturbative series based on the analysis of so-called renormalon chains. The perturbative analysis is complemented by a model-independent description o...
متن کاملhadronic τ decays in the resonance effective action of QCD ∗
Until present the study of the form factors associated to the vector and axial–vector components of the hadronic weak current has been carried out with a plethora of modelizations of the underlying strong interactions. While of importance to get an understanding of the dynamics involved, the amount and quality of the experimental data start to show some discrepancies with the analysed models. M...
متن کاملContour-improved versus fixed-order perturbation theory in hadronic τ decays
The hadronic decay rate of the τ lepton serves as one of the most precise determinations of the QCD coupling αs. The dominant theoretical source of uncertainty at present resides in the seeming disparity of two approaches to improving the perturbative expansion with the help of the renormalisation group, namely fixed-order and contourimproved perturbation theory. In this work it is demonstrated...
متن کاملHadronic Spectral Functions in Lattice QCD
Among various dynamical quantities in quantum chromodynamics (QCD), the spectral functions (SPFs) of hadrons play a special role in physical observables (See e.g. [1,2]). A well-known example is the cross section of the e+e− annihilation into hadrons, which can be expressed by SPF in the vector channel. SPF at finite temperature (T ) and/or baryon density is also a key concept to understand the...
