Renormalization group improved and determination from hadronic decays
B. Ananthanarayan, Diganta Das, M. S. A. Alam Khan
We determine the strange quark mass () and quark mixing element , and their joint determination from the Cabibbo suppressed hadronic decays in various…
Prospects for precise predictions of in the Standard Model
G. Colangelo, M. Davier, A. X. El-Khadra +79
We discuss the prospects for improving the precision on the hadronic corrections to the anomalous magnetic moment of the muon, and the plans of the Muon Theory Initiative to…
Test of analyticity and unitarity for the pion form-factor data around the resonance
B. Ananthanarayan, Irinel Caprini, Diganta Das
High-statistics data on the cross section and the pion vector form factor have been obtained recently by several collaborations. Unfortunately, there are some te…
The QCD Static Energy using Optimal Renormalization and Asymptotic Padé-approximant Methods
B. Ananthanarayan, Diganta Das, M. S. A. Alam Khan
The perturbative QCD static potential and ultrasoft contributions, which together give the static energy, have been calculated to three- and four-loop order respectively, by severa…
The three-loop QED contributions to the of charged leptons with two internal fermion loops and a class of Kampé de Fériet series
B. Ananthanarayan, Samuel Friot, Shayan Ghosh
The three-loop QED mass-dependent contributions to the of each of the charged leptons with two internal closed fermion loops, sometimes called $A^{(6)}_3\left(\frac{m_1}{m_2}…
Asymptotic analysis of Feynman diagrams and their maximal cuts
B. Ananthanarayan, Abhijit B. Das, Ratan Sarkar
The ASPIRE program, which is based on the Landau singularities and the method of power geometry to unveil the regions required for the evaluation of a given Feynman diagram asympto…
