$\rho$ and $K^{\ast }$ resonances on the lattice at nearly physical quark masses and $N_f=2$

Gunnar S. Bali, Sara Collins, Antonio Cox +4

Working with a pion mass $m_{\pi }\approx 150$ MeV, we study $\pi \pi$ and $K\pi$ scattering using two flavours of non-perturbatively improved Wilson fermions at a lattice spacing $a\approx 0.…
