Transitions of few-hadron systems from QCD

• Felipe Ortega Gama (UC Berkeley)
• Felipe Ortega Gama (UC Berkeley)

The study of multi-hadron transitions brings to light information, beyond what masses and decay properties can tell us, about the short-lived resonances in the QCD spectrum. The lattice formulation of QCD (LQCD) can access these non-perturbative observables from first-principles, provided systematic effects can be kept under control. I will describe robust techniques that have been devised to remove power-law finite-volume systematics effects that arise when extracting multi-hadron observables. These techniques will be described in the context of a recent calculation of the vector form factor of the pion, where both spacelike and timelike regions where extracted simultaneously.
