The -meson leading-twist distribution amplitude
Benoît Blossier, Mariane Mangin-Brinet, José Manuel Morgado Chávez +1
In this project, we employ the short-distance factorization to compute the distribution amplitude of the -meson from Lattice QCD at leading twist. We employ a set of CLS $N_f=…

The distribution amplitude of the -meson
Benoît Blossier, Mariane Mangin-Brinet, José Manuel Morgado Chávez +1
In this proceeding we determine the distribution amplitude of the -meson from first principles. This quantity appears as a consequence of factorization theorems, and it is nec…

The hadronic running of the electromagnetic coupling and electroweak mixing angle
Teseo San José, Hartmut Wittig, Marco Cè +7
We present results for the hadronic running of the electromagnetic coupling and the weak mixing angle from simulations of lattice QCD with flavours of -improved Wil…
