California Amplitudes Meeting 2021

We are hosting the virtual California Amplitudes meeting on March 24/25 2021. For those of you who have not participated in CAmplitudes in the past, it is a very informal annual meeting of people in California that work on scattering amplitudes and related topics.

This year we are opening the meeting to a slightly wider audience and perhaps there will be around 40 participants in total.
We will have a couple of longer talks by non-CA speakers, several shorter talks by locals, and plenty of time for discussions.

A preliminary schedule and further information can be found on the website (  which we will update with more information closer to the date of the workshop.

We hope to see many of you in March.

QCD Meets Gravity Workshop 2019

December 9-13, 2019

black hole mergerThis is the fifth 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 is 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, including the important problem of gravitational radiation from compact astrophysical objects. This meeting brings together experts in both gauge and gravity theories including supersymmetric extensions, and focus bringing the methodologies developed for gauge theories to handle problems in gravity.

QCD Evolution Workshop 2020

Apr 27 - May 1, 2020

QCD Evolution Workshop 2020A main objective of QCD Evolution Workshop is to provide a forum to discuss the recent scientific accomplishments in areas such as Transverse Momentum Distributions (TMDs), Generalized Parton Distributions (GPDs), and small-x physics, together with advances in perturbative and non-perturbative techniques within Quantum Chromodynamics (QCD), such as lattice QCD and effective field theory techniques.

Sudipfest 2019

April 4-6, 2019 at the UCLA Luskin Conference Center, Optimist Room

Organizers: Zvi Bern (UCLA), Stuart Brown (UCLA), Joseph Rudnick (UCLA)

Sudip ChakravartySudip ChakravartyThis three-day workshop will celebrate the career of Distinguished Professor Sudip Chakravarty, UCLA Physics & Astronomy.

Professor Chakravarty's research interest involves quantum theory of collective behavior of electronic systems. He is interested in theories of high temperature superconductivity, dissipative quantum systems, quantum phase transition and criticality, localization transition in interacting systems, and the concept of von Neumann entropy in quantum phase transitions. He is currently actively interested in competing electronic states in high temperature superconductors, in particular in understanding the surprising magnetic quantum oscillations discovered recently in these superconductors.

His past accomplishments include theories of quantum phase transition in double well and arrays of Josephson junction systems coupled to a dissipative bath, criticality of Ising spin glass through high-order series expansion, path-integral analysis of electronic weak localization in disordered electrons, quantum magnetism and criticality in Heisenberg magnets in relation to high temperature superconductors, electron-electron interaction based mechanism of superconductivity in doped fullerenes, frustrated kinetic energy driven superconductivity in multilayered high temperature superconductors, and the proposal of the hidden d-density wave order as an explanation of the enigmatic pseudogap phase in high temperature superconductors, which he is still vigorously pursuing.

UCLA 2019 Santa Fe Jets and Heavy Flavor Workshop

January 28-30, 2019, 8:30am-5:30pm, UCLA IDRE Portal, Room 5628 Math Sciences Building

Organizers: Huan Huang, Zhongbo Kang (Chair), Christopher Lee, Cesar da Silva, Ivan Vitev

This workshop, to be held at the UCLA IDRE Portal in the Math Sciences Building, will bring together senior researchers, postdoctoral fellows and talented graduate students to discuss the exciting recent developments and future directions in high energy and nuclear science. The purpose of the 2019 Santa Fe Jets and Heavy Flavor workshop is to summarize the accomplishments and provide guidance for the community effort in the areas of hadronic jets, jet substructure, quarkonia and open heavy flavor, with emphasis on perturbative Quantum Chromodynamics (pQCD) and Soft Collinear Effective Theory (SCET).

SchwingerFest2018: g-2

December 3rd - 5th, 2018
UCLA Physics & Astronomy Department

Organizers: Zvi Bern (UCLA), Thomas Blum (UConn), Lance Dixon (SLAC), William Marciano (Brookhaven)

Julian SchwingerJulian Schwinger2018 is Julian Schwinger's Centennial.  To help celebrate Julian Schwinger's legacy, the Mani L. Bhaumik Institute will be holding a workshop on the latest developments on the anomalous magnetic moment of leptons, especially the muon.  A long-standing 3 sigma discrepancy between theory and experiment points towards new physics beyond the Standard Model. Is it real? This workshop is particularly timely given the ongoing Fermilab muon g-2 experiment, which will reach unprecedented precision.  In order to fully interpret the upcoming experimental results, it is essential to improve the theoretical uncertainty in difficult to compute hadronic contributions, especially to the light-by-light contribution.   Recent progress in lattice gauge theory calculations suggests that it is possible to achieve this.  The primary purpose of this workshop is to bring together leading experts to assess the situation and to identify paths towards new breakthroughs.
