Invariant-mass threshold resummation for the production of four top quarks at the LHC

Journal article

The elliptic and triangular flow of charged particles are measured using two-particle angular correlations in pPb collisions in the pseudorapidity range 2.0 <|η|< 4.8.The data sample was collected by the LHCb experiment in 2016 at a centre-of-mass energyper nucleon pair of √sNN = 8.16 TeV, containing in total approximately 1.5 billion collisionevents. Non-flow contributions are obtained in low-multiplicity collisions and subtracted toextract the flow harmonics. The results are presented as a function of event multiplicity andhadron transverse momentum. Comparisons with a full (3+1)D dynamic model indicate thatit overestimates the measured elliptic flow. A comparison between the forward and backwardregions reveals no significant differences in flow parameters, suggesting that final-state effectsmay dominate over initial-state effects in the origin of flow in small systems
