The production yields of antideuterons and antiprotons are measured in pp collisions at a center-of-mass energy of *%𝑠 = 13 TeV, as a function of transverse momentum (𝑝&sub(T)) and rapidity (𝑦), for the rst time rapidity-dierentially up to |𝑦| = 0.7. The measured spectra are used to study the 𝑝&sub(T) and rapidity dependence of the coalescence parameter 𝐵&sub(2), which quanties the coalescence probability of antideuterons. The 𝑝&sub(T) and rapidity dependence of the obtained 𝐵&sub(2) is extrapolated for 𝑝&sub(T) > 1.7 GeV/𝑐 and |𝑦| > 0.7 using the phenomenological antideuteron production model implemented in Pythia 8.3 as well as a baryon coalescence afterburner model based on EPOS 3. Such measurements are of interest to the astrophysics community, since they can be used for the calculation of the ux of antinuclei from cosmic rays, in combination with coalescence models.
