Characterization of the quantum state of top quark pairs produced in proton-proton collisions at $\sqrt{s}$ = 13 TeV using the beam and helicity bases

Measurements of the spin correlation coefficients in the beam basis are presented for top quark-antiquark (𝑡⁢$\overline{𝑡}$) systems produced in proton-proton collisions at √𝑠 =13 TeV collected by the CMS experiment in 2016–2018, and corresponding to an integrated luminosity of 1...
