Proton-nucleus (p+A) collisions have long been recognized as a crucial component of the LHC heavy ion program. However, significant experimental and theoretical developments have occurred in this area since the last broad-based discussions of p+A collisions at the LHC. In particular, d+Au measurements at RHIC have provided decisive benchmark experiments for discoveries in the RHIC nucleus-nucleus program and show the potential for elucidating the low-x structure of matter.
 
The goals of this workshop are to assess the current state of the art in p+A physics and to identify the milestones required for optimal implementation of the p+A running in the LHC program. The focus will be on the following topics:

LHC machine operation with p+A John Jowett, Stephan Maury, Andreas Morsch

LHC experiments with p+A Michiel Botje (ALICE), Helio Takai (ATLAS), Bolek Wyslouch (CMS).

p+A as a benchmark for A+A Nestor Armesto, Carlos A. Salgado, J.W. Qiu

small-x physics with p+A Dima Kharzeev, Alex Kovner, Marzia Nardi, Larry McLerran.

Ultraperipheral Collisions Kai Hencken, Pablo Yepes, Spencer Klein, Ramona Vogt.

Following the workshop, the important issues for further planning will be summarized in a brief document (~20 pages).
