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.

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
/ Lykasov, Gennady (Dubna, JINR) ; Brodsky, Stanley J (SLAC) ; Bednyakov, V A (Dubna, JINR) ; Lipatov, A V (SINP, Moscow) ; Smiesko, J (Comenius U.) ; Tokar, S (Comenius U.)
/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. [...]

$\alpha_s$(2019) discussions summary
/ Alekhin, Sergey (Hamburg U., Inst. Theor. Phys. II ; Serpukhov, IHEP) ; Barreiro, Fernando (U. Autonoma, Madrid (main)) ; Bethke, Siegfried (Munich, Max Planck Inst.) ; Brambilla, Nora (Munich, Tech.

A summary of the main points of discussion raised during the talks and their follow-up questions,as well as in the round table of the last day of the $α_s$ (2019) workshop, is presented. The discussions not only focused on particular issues affecting each one of the individual $α_s$ extractions, but also on the current PDG categorization of $α_s$ measurements and on the methods used to average them into a single $α_s$ ($m_Z$) value.

Dept.) ; Battaglieri, Marco (INFN, Genoa) ; Echenard, Bertrand (Caltech) ; Essig, Rouven (SUNY, Stony Brook) ; Graham, Matthew (SLAC) ; Izaguirre, Eder (Perimeter Inst. Theor. Phys.) ; Jaros, John (SLAC) ; Krnjaic, Gordan (Fermilab) ; Mardon, Jeremy (Stanford U., Phys. Dept.) ; Morrissey, David (TRIUMF) et al.
This report, based on the Dark Sectors workshop at SLAC in April 2016, summarizes the scientific importance of searches for dark sector dark matter and forces at masses beneath the weak-scale, the status of this broad international field, the important milestones motivating future exploration, and promising experimental opportunities to reach these milestones over the next 5-10 years..
