Comment on $\mu p$ and $\mu A$ Luminosities of Muon-Ion Collider at BNL

Luminosities of muon-proton and muon-nucleus collisions at a recently proposed muon-ion collider (MuIC) at Brookhaven National Laboratory (BNL) in the USA have been estimated using A Luminosity Optimizer for High Energy Physics (AloHEP) software keeping in mind beam-beam tune-shift values. It is shown that L${}_{\mu p}$ = 3.6x10${}^{31}$ cm${}^{-2}$s${}^{-1}$ and L${}_{\mu -\mathrm{A}\mathrm{u}}$ = 2.84x10${}^{27}$ cm${}^{-2}$s${}^{-1}$ values can be achieved at MuIC. The physics search potential of the collider is superior to HERA. However, LHeC will provide 2 orders of higher luminosities at approximately same center-of-mass (CoM) energies.
