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…
Goldstone Boson Scattering with a Light Composite Scalar
T. Appelquist, R. C. Brower, K. K. Cushman +14
The appearance of a light composite scalar resonance in nearly conformal gauge-fermion theories motivates further study of the low energy structure of these theories. To this…
