Abstract:

In this note, we discuss how the future HL-LHC program will enable highly precise measurements of flow observables in small systems. Projections of the statistical uncertainties achievable for symmetric cumulant analyses at

\sqrt{\text{s}} = 13

TeV for pp collisions and at

\sqrt{\text{s}_{NN}} = 5.02

TeV for pPb collisions are presented. The improvement in the symmetric cumulant precision by increasing the pp beam energy to 14 TeV, while extending the CMS tracker pseudorapidity coverage to

|\eta| < 4

, is also shown. In addition, we show how the HL-LHC will allow for elliptic flow measurements of

D^0

and

J/\psi

mesons in 8.16 TeV pPb collisions that are a factor of two more precise than currently possible.
