Measurement of antiproton production in $\mathrm{pHe}$ collisions at $\sqrt{s_{NN}}=110$ GeV

LHCb collaboration, R. Aaij, C. Abellán Beteta +839

The cross-section for prompt antiproton production in collisions of protons with an energy of $6.5$ TeV incident on helium nuclei at rest is measured with the LHCb experiment from…
