Workshop on Controlled Fabrication of NV Centers in Diamonds

March 10th-11th, 2018
UCLA Physics & Astronomy Department

The properties of NV centers in diamonds have been extensively explored over the past 20 years. Single-site experiments with extraordinary precision and resolution have been demonstrated, raising expectations for revolutionary metrology/spectroscopy applications. However, all potential applications require a highly reproducible and precise placement of NV centers in pure synthetic diamond crystals.

Confronted with the requirements of proposed applications, the Workshop intends is to examine the limits and potentials of techniques used to control the NV center’s concentration, orientation, and relative depth below the diamond surface, while maintaining their excellent sensing properties. Ultimately, realizing the full potential of many of the proposed applications will require producing NV centers at a precision, scale and cost beyond what is currently possible. By bringing together experts in CVD, MWP-CVD growth, ion-implantation, and diamond processing with the instrument builders who are using the NV centers, the workshop will explore the intersection of future needs with manufacturing capabilities.

QCD Meets Gravity Workshop 2017

December 11th-15th, 2017
UCLA Physics & Astronomy Department

This is the third 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), Radu Roiban (Penn State), Jaroslav Trnka (UC Davis), Henrik Johansson (Uppsala).

Advances in QCD and Applications to Hadron Colliders Workshop

November 8-10, 2017 (Wednesday, Thursday, Friday)
UCLA Physics & Astronomy Department

There have been exciting recent progress in the field of QCD, including: new understanding of factorization, resummation and power corrections that give insight into effective field theories; a new ability to compute NNLO and beyond perturbative corrections that allow precision jet phenomenology at the LHC and other future colliders; better organizing principles for computing multi-loop corrections; the development of new parton showers with higher-order matching; and, many other new advances. This workshop will bring together a small group of experts to allow for targeted discussions that identify possible future advances that merge these new ideas. The topics we plan to discuss include but are not limited to:

• Factorization in effective field theory, including the impact of Glauber logs and power corrections;
• Resummation-based subtraction techniques and their latest precision phenomenology results;
• Recent advances in parton shower Monte Carlos;
• New PDFs and the impact of resumation on improving their uncertainty;
• Combining QCD and electroweak effects in precision observables;
• Developments in calculating two-loop virtual corrections and beyond.

This is the second year for this workshop following a very successful "Advances in QCD and Applications to Hadron Colliders 2016 Workshop" held at Argonne National Laboratory October 26 - 28, 2016. This year the workshop will be co-sponsored by Mani L. Bhaumik Institute for Theoretical Physics at UCLA and Argonne National Laboratory. The workshop will be held at UCLA Department of Physics and Astronomy.

Organizers: Radja Boughezal (ANL), Fernando Febres Cordero (Freiburg), Zhongbo Kang (UCLA), Mao Zeng (UCLA).

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).
