Perturbative Expansions in QCD Improved by Conformal Mappings of the Borel Plane
Irinel Caprini, Jan Fischer, Gauhar Abbas +1
Perturbation expansions appear to be divergent series in many physically interesting situations, including in quantum field theories like quantum electrodynamics (QED) and quantum…
Analytic representation of in two loop chiral perturbation theory
B. Ananthanarayan, Johan Bijnens, Samuel Friot +1
We present an analytic representation of as calculated in three-flavour two-loop chiral perturbation theory, which involves expressing three mass scale sunsets in terms o…
Inclusive spin-momentum analysis and new physics at a polarized electron-positron collider
B. Ananthanarayan, Saurabh D. Rindani
We consider the momentum distribution and the polarization of an inclusive heavy fermion in a process assumed to arise from standard-model (SM) -channel exchange of a virtual $γ…
Electromagnetic charge radius of the pion at high precision
B. Ananthanarayan, Irinel Caprini, Diganta Das
We present a determination of the pion charge radius from high precision data on the pion vector form factor from both timelike and spacelike regions, using a novel formalism based…
Optimal renormalization and the extraction of strange quark mass from semi-leptonic -decay
B. Ananthanarayan, Diganta Das
We employ optimal renormalization group analysis to semi-leptonic -decay polarization functions and extract the strange quark mass from their moments measured by the ALEPH and O…
An Analytic Analysis of the Pion Decay Constant in Three-Flavoured Chiral Perturbation Theory
B. Ananthanarayan, Johan Bijnens, Shayan Ghosh
A representation of the two-loop contribution to the pion decay constant in chiral perturbation theory is presented. The result is analytic upto the contribution of the thr…
