Measurement of prompt and non-prompt ${\rm D}^{\rm *+}$-meson spin alignment in pp collisions at $\sqrt{s}$ = 13.6 TeV$

A precise measurement of prompt and non-prompt ${\rm D}^{\rm *+}$-meson spin alignment with respect to the helicity and production axes in proton-proton (pp) collisions at $\sqrt{s} = 13.6$ TeV is presented, using data collected with the ALICE experiment at the LHC. The spin alignment is quantified by measuring the dia...
