高p_T触发的Delta-eta、Delta-phi相关
High p_T Triggered Delta-eta,Delta-phi Correlations over a Broad Range in Delta-eta
摘要：
首次测量了高横动量带电强子（p_T > 2.5GeV/c）与所有伴生粒子在连续赝快度接受范围（-4<Delta-eta<2）内的短程（小Delta-eta）和长程（大Delta-eta）关联.在这些诉讼中，各种近侧和远侧的相关结构的功能进行了讨论，作为一个功能的中心在金+金碰撞测量的PHOBOS在sqrt（S_NN）=200 GeV。特别是，这种测量可以更完整地确定脊结构的纵向范围，首先由STAR合作在有限的eta范围内观察到。在中心碰撞中，脊至少持续到Δ-eta =4，随着碰撞变得更加外围，脊的大小逐渐减小，直到它在Npart=80附近消失。
英文摘要：
The first measurement of pseudorapidity (Delta-eta) and azimuthal angle (Delta-phi) correlations between high transverse momentum charged hadrons (p_T > 2.5 GeV/c) and all associated particles is presented at both short- (small Delta-eta) and long-range (large Delta-eta) over a continuous pseudorapidity acceptance (-4<Delta-eta<2). In these proceedings, the various near- and away-side features of the correlation structure are discussed as a function of centrality in Au+Au collisions measured by PHOBOS at sqrt(s_NN)=200 GeV. In particular, this measurement allows a much more complete determination of the longitudinal extent of the ridge structure, first observed by the STAR collaboration over a limited eta range. In central collisions the ridge persists to at least Delta-eta=4, diminishing in magnitude as collisions become more peripheral until it disappears around Npart=80.
