alpha_s from tau decays revisited
D. Boito, O. Cata, M. Golterman +4
Being a determination at low energies, the analysis of hadronic tau decay data provides a rather precise determination of the strong coupling alpha_s after evolving the result to M…
Issues in determining alpha_s from hadronic tau decay and electroproduction data
D. Boito, O. Cata, M. Golterman +4
We discuss some key issues associated with duality-violating and non-perturbative OPE contributions to the theoretical representations of light quark current-current two-point func…
2d affine XY-spin model/ 4d gauge theory duality and deconfinement
Mohamed M. Anber, Erich Poppitz, Mithat Unsal
We introduce a duality between two-dimensional XY-spin models with symmetry-breaking perturbations and certain four-dimensional SU(2)and SU(2)/Z_2 gauge theories, compactified on a…
On the Extraction of the Strong Coupling from Hadronic Tau Decay
Diogo Boito, Oscar Catà, Maarten Golterman +4
The finite energy sum rule extraction of the strong coupling α_s from hadronic τ decay data provides one of its most precise experimental determinations. As precision improves, sma…
A new determination of α_s from hadronic τ decays
Diogo Boito, Oscar Cata, Maarten Golterman +4
We present a new framework for the extraction of the strong coupling from hadronic τdecays through finite-energy sum rules. Our focus is on the small, but still significant non-per…
Compressed Sensing with General Frames via Optimal-dual-based -analysis
Yulong Liu, Tiebin Mi, Shidong Li
Compressed sensing with sparse frame representations is seen to have much greater range of practical applications than that with orthonormal bases. In such settings, one approach t…
