Status of the hadronic light-by-light contribution to the muon and holographic QCD predictions
Anton Rebhan, Luigi Cappiello, Josef Leutgeb +1
We review the recent progress made with regard to the hadronic light-by-light (HLbL) contribution to the Standard Model prediction of the muon anomalous magnetic moment and how wel…
Divergences in the hadronic light-by-light amplitude of the holographic soft-wall model
Josef Leutgeb, Jonas Mager, Anton Rebhan
We use the WKB approximation to uncover divergences and instances of non-commuting limits in a large class of holographic soft-wall models. We show that the infinite sum over singl…
The anomalous magnetic moment of the muon in the Standard Model: an update
R. Aliberti, T. Aoyama, E. Balzani +232
We present the current Standard Model (SM) prediction for the muon anomalous magnetic moment, , updating the first White Paper (WP20) [1]. The pure QED and electroweak contri…
Longitudinal short-distance constraints on hadronic light-by-light scattering and tensor meson contributions to the muon
Jonas Mager, Luigi Cappiello, Josef Leutgeb +1
Short-distance constraints from the operator product expansion in QCD play an important role in the evaluation of the hadronic light-by-light scattering contribution to the anomalo…
Tensor meson transition form factors in holographic QCD and the muon
Luigi Cappiello, Josef Leutgeb, Jonas Mager +1
Despite the prominence of tensor mesons in photon-photon collisions, until recently their contribution to the hadronic light-by-light (HLbL) scattering part of the anomalous magnet…
Superconnections in AdS/QCD and the hadronic light-by-light contribution to the muon
Josef Leutgeb, Jonas Mager, Anton Rebhan
In this paper, we consider hard-wall AdS/QCD models extended by a string-theory inspired Chern-Simons action in terms of a superconnection involving a bi-fundamental scalar field w…
