69. Jets in Heavy Ion Collisions

Prof. Dennis Perepelitsa (University of Colorado Boulder)

2/3/17, 9:00 AM

Fully reconstructed jets have become a sophisticated and widely-used tool through which to probe the properties of the quark-gluon plasma created in nucleus-nucleus collisions at RHIC and the LHC. In this talk, I will give an experimental overview of some of the the latest developments in these measurements, including recent results from the LHC Run 2 Pb+Pb data-taking on high-statistics...

70. Photon at NLO as a CGC probe in p+A collisions

Sanjin Benic (University of Zagreb)

2/3/17, 9:25 AM

We report on a first NLO computation of photon production in p+A collisions at collider energies within the Color Glass Condensate framework, significantly extending previous LO results. At central rapidites, our result is the dominant contribution and probes multi-gluon correlators in nuclei. At high photon momenta, the result is directly sensitive to the nuclear gluon distribution. We...

20. From small to moderate-x: beyond the eikonal approximation

Dr Andrey Tarasov (BNL)

2/3/17, 9:50 AM

In recent years significant progress has been made in our understanding of the small-x physics beyond the eikonal approximation. Rigorous analysis of the dependence on the transverse momentum helps us better understand not only physics of the Regge limit, but to connect it to the kinematic limit of the moderate-x as well. I’ll describe the technique we used in calculation of TMD evolution...

30. An Effective Theory for small-R jets

Christopher Lee (Los Alamos National Laboratory)

2/3/17, 10:10 AM

Logarithms of jet radii R become large in jet cross sections when R is small. In exclusive jet cross sections with jets of energy Q and a veto on additional jets of energy E, we find that logs of R come from ratios of not one but two hierarchies of scales, QR over Q and ER over E. We construct an effective field theory with modes for both hard-collinear and soft-collinear scales QR and ER,...
