Charge Correlations in Heavy Ion Collisions

The view to the quark gluon plasma phase (QGP) in heavy ion collisions is obscured by events taking place later on. One way around this is to focus on conserved charges, such as electric charge, baryon number or strangeness.1,2 Later evolution can only change these charges locally, through pair creation or annihilation, but charge fluctuations with long enough wavelengths will remain unchanged....

System Size Dependence of Azimuthal Correlations in Relativistic Heavy Ion Collisions

Systematic comparisons of jet pair correlations obtained in Cu+Cu and Au+Au collisions at √ sNN =200 GeV are presented. The measured jet-pair distributions for both systems show strong modification of the away-side jet. For the same number of participating nucleons, the modification does not show a strong dependence on the collision system. It is suggested that such comparisons can provide impo...

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...
