Topical Workshop on QCD Structure of Nucleons in the Modern Era

May 4-6, 2017 (Thursday, Friday, Saturday)
UCLA Physics & Astronomy Department

The fundamental laws of QCD are elegantly concise; however, understanding the structural complexity of nucleons in terms of quarks and gluons governed by those laws is one of the most important challenges facing subatomic physics today, and is of fundamental importance in science. There have been tremendous advancements and breakthroughs following the vast investigations in the last few decades. Current and future projects at world facilities, such as RHIC at Brookhaven National Lab and CEBAF at Jefferson Lab, and the planed electron-ion collider (EIC) in the US, will undoubtedly provide new opportunities to further deepen our understanding of the fundamental questions associated with QCD structure of nucleons. In particular, the EIC will provide unprecedented precision in exploring the nucleon structure and address many of the outstanding questions. In line with these experimental advances and future plans, we envision that the theory developments must follow.

We intend to gather a small group of experts working on QCD to discuss the current status of the theoretical developments, and future perspectives. We will mainly focus on recent developments on the nucleon tomography, in particular theory and phenomenology of confined motion of quarks and gluons inside the nucleons, encoded in the transverse momentum dependent distributions (TMDs). The meeting will be organized in an informal way, mainly focusing on the exchange of ideas.

Organizers: Zhongbo Kang (UCLA), Jianwei Qiu (JLab), Feng Yuan (LBL).

QCD Meets Gravity Workshop 2016

December 5-9, 2016
UCLA Physics & Astronomy Department

This is the second in a series of meetings for researchers interested in the remarkable correspondence between Yang-Mills theory and gravity, known as the double-copy construction. An early manifestation of this is the KLT relations.

The BCJ double-copy construction has greatly simplified multiloop perturbative computations in gravity theories, leading to new insight into the ultraviolet properties of gravity theories. Currently there an intense global research activity to understand the origin of the relation as well as to apply it to more general classical solutions in General Relativity. This meeting will bring together experts in both QCD and gravity (including supersymmetric extensions), and focus on the development of common methodologies for handling both theories.

Organizers: Zvi Bern (UCLA), Clifford Chueng (Caltech), Donal O'Connell (Edinburgh), Jaroslav Trnka (UC Davis).

California Amplitudes Meeting

October 10-12, 2016
UCLA Physics & Astronomy Department

This is the second in a series for meetings for researchers in California interested in scattering amplitudes. The first was held at UC Davis.

The focus is on recent topic in scattering amplitudes, including mathematical aspects of positive Grassmannian and Amplituhedron, non-planar on-shell diagrams, ratio functions in N=4 SYM, symbols and the basis of hexagon functions, multi-loop integrated amplitude, the CHY formula, BCJ duality, double-copy relations and applications to effective field theories.

Organizers: Zvi Bern (UCLA), Clifford Cheung (Caltech), Lance Dixon (SLAC), Jaroslav Trnka (UC Davis).
