The $I=1$ pion-pion scattering amplitude and timelike pion form factor from $N_{\mathrm{f}}=2+1$ lattice QCD

Christian Andersen, John Bulava, Ben Hörz +1

The elastic $I=1$ $p$-wave $\pi \pi$ scattering amplitude is calculated together with the isovector timelike pion form factor using lattice QCD with $N_{\mathrm{f}}=2+1$ dynamical quark flav…
