Abstract

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_T) and rapidity (y), for the first time rapidity-differentially up to |y|=0.7. The measured spectra are used to study the p_T and rapidity dependence of the coalescence parameter B₂, which quantifies the coalescence probability of antideuterons. The p_T and rapidity dependence of the obtained B₂ is extrapolated for p_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 flux of antinuclei from cosmic rays, in combination with coalescence models.
