Description

New (9/May/2019): A summary of the workshop, prepared by the session convenors is available on the arXiv at arXiv:1905.00059.

The aim of this workshop is to bring together experts and those interested in measuring QED in the presence of strong fields at and above the Schwinger critical field. It is organised jointly by DESY and the Stanford PULSE institute. The pioneering experiment, E144 at SLAC, measured multi-photon absorption in Compton scattering and e+e- pair production in electron--photon interactions but never reached the Schwinger critical field value. With the advances in laser technology, in particular, new experiments are being considered which should be able to measure non-perturbative QED and its transition from the perturbative regime. This workshop will review the physics case and current theoretical predictions for QED and even effects beyond the Standard Model in the interaction of a high-intensity electron bunch with the strong field of the photons from a high-intensity laser bunch. The world's various electron beam facilities will be reviewed, along with the challenges of producing and delivering laser beams to the interaction region. Possible facilities and sites that could host such experiments will be presented, with a view to experimentally realising the Schwinger critical field during the 2020s.

The workshop will have two days of talks, with an informal drinks reception on the evening before and a workshop dinner. The registration fee is 120 Euro and will cover the reception, the lunches, the workshop dinner and coffee breaks during the two days. Posters can be presented during the workshop. In case you are interested please email the title and a short abstract to beate.heinemann@desy.de and matthew.wing@desy.de

      The field of laser-matter interaction traditionally deals with the response of atoms, molecules, and plasmas to an external light wave. However, the sustained technological progress is opening up the possibility of employing intense laser radiation to trigger or substantially influence physical processes beyond atomic-physics energy scales. Available optical laser intensities exceeding 1022  W/cm2 can push the fundamental light-electron interaction to the extreme limit where radiation-reaction effects dominate the electron dynamics, can shed light on the structure of the quantum vacuum, and can trigger the creation of particles such as electrons, muons, and pions and their corresponding antiparticles. Also, novel sources of intense coherent high-energy photons and laser-based particle colliders can pave the way to nuclear quantum optics and may even allow for the potential discovery of new particles beyond the standard model. These are the main topics of this talk, which is devoted to a review of recent investigations on high-energy processes within the realm of relativistic quantum dynamics, quantum electrodynamics, and to a smaller degree nuclear and particle physics, occurring in extremely intense laser fields.
