- Ratios R(Q) obtained with the opposite-hemisphere, same-charge reference samples for data (dots) and MC with no BEC effect (crosses).:

- Double ratios for the 0.9 TeV data, using the opposite-hemisphere, same-charge reference samples for combinations enriched, using a dE/dx measurement, in pion-pion pairs (dots) and in pion--non-pion pairs (open circles), respectively.:

- Fits to the double ratios with exponential (solid lines) and Gaussian (dashed lines) functions, for 0.9 TeV (top) and 2.36 TeV (bottom) data. The range 0.6<Q<0.9 GeV is excluded from the fits.:

- Values of the \lambda (top) and r (bottom) parameters as a function of the charged-particle multiplicity in the event for combined (dots) and opposite-hemisphere, same-charge (open circles) reference samples, at 0.9 TeV. The errors shown are statistical only. The points are placed on the horizontal scale at the average of the multiplicity distribution in the corresponding bin.:
