“…That is why it was a surprise to find in 2004 and confirm later [158,159,160,161,162,163,164,165,166,167,168] the so-called double-humped events in central nucleus-nucleus collisions at RHIC. In fact, the obtained distributions closely remind those published by Cherenkov in 1937 when he used the projection of famous rings on their diameter and got the doublehumped structure (e.g., see [169]).…”

“…The KLM consists of alternating layers of charged particle detectors and 4.7 cmthick iron plates, which are the magnetic flux return in the barrel and endcap regions. 6) There are 15 detector layers and 14 iron layers in the octagonal barrel region and 14 detector layers in each of the forward and backward end-caps. The iron plates provide a total of 3.9 interaction lengths of material for a particle traveling normal to the detector planes.…”

“…Recently many theoretical models have been proposed to describe the phenomenon : Mach-cone shock waves generated by large energy deposition in the medium [23], conical emission due to Cherenkov radiation [24], the excitation of collective plasmon waves [25], large angle gluon radiation [26,27], strong parton cascade [28][29][30], jets deflected by radial flow [25,31] and path-length dependent energy loss [32]. It has also been observed previously that the double peak structure in the dihadron angular correlation strongly depends on φ s , the trigger particle azimuthal angle with respect to the direction of the event plane [33,34]. The angular correlation distributions on the away side are different between in-plane and out-ofplane orientations which indicate a strong path-length effect on parton-medium interactions [34].…”

Dihadron azimuthal angle correlations relative to the reaction plane have been investigated in Au + Au collisions at √ sNN = 200 GeV using a multi-phase transport model (AMPT). Such reaction plane azimuthal angle dependent correlations can shed light on path-length effect of energy loss of high transverse momentum particles propagating through the hot dense medium. The correlations vary with the trigger particle azimuthal angle with respect to the reaction plane direction, φs = φT − ΨEP , which is consistent with the experimental observation by the STAR collaboration. The dihadron azimuthal angle correlation functions on the away side of the trigger particle present a distinct evolution from a single peak to a broad, possibly double peak, structure when the trigger particle direction goes from in-plane to out-of-plane of the reaction plane. The away-side angular correlation functions are asymmetric with respect to the back-to-back direction in some regions of φs, which could provide insight on testing v1 method to reconstruct the reaction plane. In addition, both the root-mean-square width (Wrms) of the away-side correlation distribution and the splitting parameter D between the away-side double peaks increase slightly with φs, and the average transverse momentum of the away-side associated hadrons shows a strong φs dependence.Our results indicate that strong parton cascade and resultant energy loss could play an important role for the appearance of a double-peak structure in the dihadron azimuthal angular correlation function on the away side of the trigger particle.
