Figure 1: Transverse momentum spectra of (a) prompt with no polarisation, (b) from b with no polarisation, (c) prompt with full transverse polarisation, and (d) prompt with full longitudinal polarisation in pp collision at TeV. The symbols with the error bars represent the experimental data with the quadratic sums of the statistical and systematic uncertainties measured by the LHCb Collaboration [15] in different rapidity ranges and scaled by different amounts marked in the panels. The curves are our fitted results.
