  As particles traverse the quark-gluon plasma (QGP) formed during a heavy ion
collision they undergo energy loss depending on the distance travelled. We
study several temperature- and velocity-weighted path length distributions of
non-interacting particles as they traverse the plasma using the Trajectum heavy
ion code, including those of back-to-back path lengths. We use event-shape
engineering (ESE) in combination with in-plane versus out-of-plane selection to
accurately control these path lengths. Lastly, we show how soft observables
depend on the different ESE classes.
