In this talk I will present results from our recent lattice QCD studies with $N_f=2+1$ clover fermions at a pion mass of approximately 320 MeV and lattice size 3.6 fm. I will discuss two processes involving the $\rho$: the first is by now the already well studied elastic scattering of two pions in P-wave with isospin 1, where the $\rho$ appears as a resonance. By analyzing the spectrum with the Luescher method we determine the strong decay width $\rho$→ $\pi\pi$. The second process is the radiative transition $\pi \gamma$ → $\pi\pi$ where we use the Briceno-Hansen-Walker-Loud approach to determine the transition amplitude in the invariant mass region near the $\rho$ resonance for both space- and time-like photon momentum. By analytic continuation to the $\rho$ pole we are able to determine also the $\rho$ radiative decay width, $\rho$→ $\pi\gamma$.<br class=""><br class="">Raza, Vincent, Carlota<br class=""><br class="">_______________________________________________<br class="">Theory-seminars mailing list<br class=""><a href="mailto:Theory-seminars@jlab.org" class="">Theory-seminars@jlab.org</a><br class="">https://mailman.jlab.org/mailman/listinfo/theory-seminars<br class=""></div></blockquote></div><br class=""></div></body></html>
