On different ways to quantize Soft-Collinear Effective Theory
Christian W. Bauer, Oscar Cata, Grigory Ovanesyan
Collinear fields in soft collinear effective theory (SCET) can be made invariant under collinear gauge transformations by multiplying them with collinear Wilson lines. We discuss h…
Unraveling duality violations in hadronic tau decays
Oscar Cata, Maarten Golterman, Santi Peris
There are some indications from recent determinations of the strong coupling constant alpha_s and the gluon condensate that the Operator Product Expansion may not be accurate enoug…
Novel patterns for vector mesons from the large-Nc limit
O. Cata, V. Mateu
We report on a relation between the decay constants of ρ-like J^{PC}=1^{--} vector mesons, which arises solely from the perturbative analysis of the VV, TT and VT correlators at or…
Migdal's model and holography
O. Cata
Migdal's model on the spectrum of vector mesons is reassessed. We discuss how its departure from a Pade approximant is closely linked to the issue of quark-hadron duality breakdown…
