50 Years of Quantum Chromodynamics
/ Gross, Franz (Jefferson Lab ; William-Mary Coll.) ; Klempt, Eberhard (Bonn U., HISKP) ; Brodsky, Stanley J. (SLAC) ; Buras, Andrzej J. (TUM-IAS, Munich) ; Burkert, Volker D. (Jefferson Lab) ; Heinrich, Gudrun (KIT, Karlsruhe, TP) ; Jakobs, Karl (Freiburg U.) ; Meyer, Curtis A. (Carnegie Mellon U.) ; Orginos, Kostas (Jefferson Lab ; William-Mary Coll.) ; Strickland, Michael (Kent State U.) et al.
This paper presents a comprehensive review of both the theory and experimental successes of Quantum Chromodynamics, starting with its emergence as a well defined theory in 1972-73 and following developments and results up to the present day. Topics include a review of the earliest theoretical and experimental foundations; the fundamental constants of QCD; an introductory discussion of lattice QCD, the only known method for obtaining exact predictions from QCD; methods for approximating QCD, with special focus on effective field theories; QCD under extreme conditions; measurements and predictions of meson and baryon states; a special discussion of the structure of the nucleon; techniques for study of QCD at high energy, including treatment of jets and showers; measurements at colliders; weak decays and quark mixing; and a section on the future, which discusses new experimental facilities or upgrades currently funded.

(Warsaw U. of Tech.) et al.
Extraction of the multi-TeV proton and lead LHC beams with a bent crystal or by using an internal gas target allows one to perform the most energetic fixed-target experiment ever. $pp$, pd and $p$A collisions at $\sqrt{s_{\rm{NN}}}$ = 115 GeV and Pb$p$ and PbA collisions at $\sqrt{s_{\rm{NN}}}$ = 72 GeV can be studied with high precision and modern detection techniques over a broad rapidity range.

Novel Phenomena in QCD: Heavy Flavor and Higgs Production at High $x_F$ from Intrinsic Heavy Quarks
/ Brodsky, Stanley J (SLAC)
Calculations from lattice gauge theory have recently verified the contribution of intrinsic heavy quarks to the non perturbative structure of the proton in QCD.The lattice results show that the intrinsic charm contribution to the proton's heavy quark distribution is maximal at large x ∼ 0.4, and that the c(x)vs.¯ c(x) distributions differ strongly. I discuss the implications of the LGTH results for LHC and EIC collider phenomenology, including Higgs and heavy hadron production at high x F , as well as the proposed AFTER fixed target facility at CERN..

Constraints on the Intrinsic Charm Content of the Proton from Recent ATLAS Data

/ATLAS Collaboration
We investigate the possibility to constrain the intrinsic charm probability in proton $w_c$ using first ATLAS data on the associated production of prompt photons and charm-quark jets in $pp$ collisions at $\sqrt{s}$ = 8 TeV. The upper limit on the intrinsic charm probability in proton $w_{ul}$ < 1.93% is obtained at the 68% confidence level. [...]

Physics perspectives with AFTER@LHC (A Fixed Target ExpeRiment at LHC)

(Los Alamos) ; Didelez, J.P. (Orsay, IPN) ; Echevarria, M.G. (INFN, Pavia) ; Ferreiro, E.G. (Santiago de Compostela U.) ; Fleuret, F. (Ecole Polytechnique) et al.
AFTER@LHC is an ambitious fixed-target project in order to address open questions in the domain of proton and neutron spins, Quark Gluon Plasma and high-$x$ physics, at the highest energy ever reached in the fixed-target mode. Indeed, thanks to the highly energetic 7 TeV proton and 2.76 A.TeV lead LHC beams, center-of-mass energies as large as $\sqrt{s_{NN}}$ = 115 GeV in pp/pA and $\sqrt{s_{NN}}$ = 72 GeV in AA can be reached, corresponding to an uncharted energy domain between SPS and RHIC.
