Quadrupole Anisotropy in Dihadron Azimuthal Correlations in Centrald+AuCollisions atsNN=200 GeV

Azimuthal Correlation in Dihadron Production

where p(c,d)⊥ and y(c,d) are, respectively, the transverse momenta and the rapidities of the outgoing hadrons and χ is the azimuthal angle, as defined in figure 1. Moreover a complete QCD study has been recently carried out for the corresponding observable in DIS processes.2 From an experimental point of view, the azimuthal correlation in pion-pair production in hadronic collision was one of th...

Trends in Yield and Azimuthal Shape Modification in Dihadron Correlations in Relativistic Heavy Ion Collisions

Transition in yield and azimuthal shape modification in dihadron correlations in relativistic heavy ion collisions.

Hard-scattered parton probes produced in collisions of large nuclei indicate large partonic energy loss, possibly with collective produced-medium response to the lost energy. We present measurements of π^{0} trigger particles at transverse momenta p{T}{t}=4-12  GeV/c and associated charged hadrons (p{T}{a}=0.5-7  GeV/c) vs relative azimuthal angle Δϕ in Au+Au and p+p collisions at sqrt[s{NN}]=2...

Azimuthal anisotropy in Au plus Au collisions at root S-NN=200 GeV

Dihadron correlations at high pT

Jet quenching in the matter created in high energy nucleusnucleus collisions provides a tomographic tool to probe the medium properties. Recent experimental results from the Relativistic Heavy-Ion Collider (RHIC) on characterization of jet production via dihadron correlations at high transverse momentum are reviewed. Expectations from the dihadron measurements for the lower energy √ sNN=62.4 Ge...
