Pion Transition Form Factor from Twisted-Mass Lattice QCD and the Hadronic Light-by-Light -pole Contribution to the Muon
C. Alexandrou, S. Bacchio, G. Bergner +14
The neutral pion generates the leading pole contribution to the hadronic light-by-light tensor, which is given in terms of the nonperturbative transition form factor $\mathcal{F}_{…
Light Scalar Meson and Decay Constant in SU(3) Gauge Theory with Eight Dynamical Flavors
Lattice Strong Dynamics Collaboration, R. C. Brower, E. Owen +15
The SU(3) gauge theory with nearly massless Dirac fermions has long been of theoretical and phenomenological interest due to the near-conformality arising from its proximit…
Hidden Conformal Symmetry from the Lattice
LSD Collaboration, T. Appelquist, R. C. Brower +14
We analyze newly expanded and refined data from lattice studies of an SU(3) gauge theory with eight Dirac fermions in the fundamental representation. We focus on the light composit…
Pseudoscalar-pole contributions to the muon at the physical point
Sebastian Burri, Gurtej Kanwar, Constantia Alexandrou +14
Pseudoscalar-pole diagrams are an important component of estimates of the hadronic light-by-light (HLbL) contribution to the muon . We report on our computation of the transit…
Pion-pole contribution to HLbL from twisted mass lattice QCD at the physical point
Sebastian Burri, Constantia Alexandrou, Simone Bacchio +13
We report on our computation of the pion transition form factor from twisted mass lattice QCD in order to determine the numerically dominant light…
Quark and gluon momentum fractions in the pion from lattice QCD
Constantia Alexandrou, Simone Bacchio, Georg Bergner +11
We perform the first full decomposition of the pion momentum into its gluon and quark contributions. We employ an ensemble generated by the Extended Twisted Mass Collaboration with…
