Both differential and total cross sections are calculated. The 95\\% C.L. exclusion limits, as well as $3\\sigma$ and $5\\sigma$ discovery limits on an ALP coupling constant versus ALP mass $m_a$ are given, using integrated luminosities of 30 ab$^{-1}$, 27 pb$^{-1}$ and 110 nb$^{-1}$. Our results are compared with the current LHC bounds. The strongest limit on the ALP coupling is obtained if $m_a \\simeq 250$ GeV for the PbPb collisi"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"The strongest limit on the ALP coupling is obtained if m_a ≃ 250 GeV for the PbPb collisions, and if m_a ≃ 1 TeV for pp or pPb collisions.
