118. Azimuthal angle correlations in forward dihadron production in pA collisions

Heikki Mäntysaari (University of Jyväskylä)

Oral presentation

Single inclusive hadron production in the forward rapidiy region in deuteron-gold collisions is well understood in the Color Glass Condensate (CGC) framework. As a complement to single inclusive spectra, detailed information is obtained with two-particle correlations. Recent measurements of the azimuthal angle correlations at RHIC have shown that there is a strong suppression of the...

49. The Future of Relativistic Heavy Ion Physics in the Foward Region in PHENIX

Richard Seto (University of California, Riverside)

Oral presentation

The field of Relativistic Heavy Ion Physics has made great strides in the past decade with the establishment of the strongly interacting Quark Gluon Plasma (sQGP) in high energy collisions of heavy ions at the Relativistic Heavy Ion Collider (RHIC) and now at the LHC. Experience has taught us that large rapidity coverage, as well as careful measurements of cold nuclear matter will be...

108. Multigluon correlations in the Color Glass Condensate

DIONYSIS TRIANTAFYLLOPOULOS (ECT*, Trento)

Oral presentation

At high energy and/or for large atomic numbers the wave-function of a generic hadron is dominated by gluon modes with soft longitudinal momenta and high occupation numbers, which can reach the state of saturation. This state, known as the Color Glass Condensate (CGC), is universal and can manifest itself in any hadronic process involving small-x partons, like deep inelastic scattering and...

109. Modeling the Impact Parameter Dependence of the nPDFs With EKS98 and EPS09 Global Fits

Ilkka Helenius (University of Jyväskylä, Department of Physics)

31/05/2012, 17:30

Oral presentation

The knowledge of the parton distribution functions (PDFs) is essential for interpreting any hard-process results from hadronic and nuclear collisions. The nuclear modifications of PDFs have been successfully determined through a global DGLAP analysis e.g. in the sets EKS98 and more recently EPS09. So far the nuclear PDFs (nPDFs) in the global fits have been taken to be spatially independent....

110. Suppression of high $p_{T}$ hadron spectra in $p+A$ collisions

Wei-Tian Deng (Frankfurt Institute for Advanced Studies)

31/05/2012, 17:50

Oral presentation

Multiple hard and semi-hard parton scatterings in high-energy $p+A$ collisions involve multi-parton correlation in both momentum and flavor inside the projectile proton which will lead to modification of the final hadron spectra relative to that in $p+p$ collisions. Such modification of final hadron transverse momentum spectra in $p+A$ collisions is studied within HIJING 2.1 Monte Carlo model...

119. Multigluon correlations in JIMWLK

Tuomas Lappi (University of Jyväskylä)

31/05/2012, 18:10

Oral presentation

Multiparticle correlations, such as the "ridge" effect in pp and AA collisions and forward dihadron correlations in pA collisions, are an important probe of the strong color fields that dominate the initial stages of a heavy ion collision. We argue that the Color Glass Condensate framework provides the most natural way to understand them. We describe recent progress in understanding...
