Abstract (data abstract)
CERN-LHC. Measurements of the angular correlations between charged trigger and associated particles in proton-Lead collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV for trigger and associated particle transverse momentum in the range 0.5 to 4 GeV (with PT_trig>PT-assoc). The correlations are measured over two units of pseudorapidity and full azimuthal angle in different intervals of event multiplicity (multiplicity classes). Two longe-range ridge-like structures, on the near and away sides, are observed when the per-trigger yield observed in low multiplicity events is subtracted from the one in high multilplisity events. The two ridge-like structures, projected on to the azimuthal angle, are quantified with the 2nd and 3rd Fourier coefficients as well as by near-side and away-side yields and widths.
