Asymptoticity of QCD and massive, oriented event-shapes
Nestor G. Gracia
This is a doctoral thesis dissertation developed in the frame of theoretical QCD predictions, with focus on two main topics. On the one hand, the large-order bahavior of perturbati…

Mathematical Aspects of the Asymptotic Expansion in Contour Improved Perturbation Theory for Hadronic Tau Decays
Néstor G. Gracia, André H. Hoang, Vicent Mateu
Recently, it was demonstrated that the discrepancy between the fixed-order (FOPT) and contour-improved (CIPT) perturbative expansions for -lepton decay hadronic spectral functio…

Towards massless and massive event shapes in the large- limit
Néstor G. Gracia, Vicent Mateu
We present results for SCET and bHQET matching coefficients and jet functions in the large- limit. Our computations exactly predict all terms of the form for…
