The reinforcement learning for autonomous accelerators collaboration
/ Santamaria Garcia, Andrea (KIT, Karlsruhe) ; Eichler, Annika (DESY) ; Xu, Chenran (KIT, Karlsruhe) ; Kaiser, Jan (DESY) ; Scomparin, Luca (KIT, Karlsruhe) ; Schenk, Michael (CERN) ; Pochaba, Sabrina (Unlisted, AT) ; Hirlaender, Simon (U. Salzburg (main))
Reinforcement Learning (RL) is a unique learning paradigm that is particularly well-suited to tackle complex control tasks, can deal with delayed consequences, and can learn from experience without an explicit model of the dynamics of the problem. These properties make RL methods extremely promising for applications in particle accelerators, where the dynamically evolving conditions of both the particle beam and the accelerator systems must be constantly considered.

Bayesian Optimization Algorithms for Accelerator Physics
/ Roussel, Ryan (SLAC) ; Edelen, Auralee L. (SLAC) ; Boltz, Tobias (SLAC) ; Kennedy, Dylan (SLAC) ; Zhang, Zhe (SLAC) ; Ji, Fuhao (SLAC) ; Huang, Xiaobiao (SLAC) ; Ratner, Daniel (SLAC) ; Garcia, Andrea Santamaria (KIT, Karlsruhe) ; Xu, Chenran (KIT, Karlsruhe) et al.
Accelerator physics relies on numerical algorithms to solve optimization problems in online accelerator control and tasks such as experimental design and model calibration in simulations. The effectiveness of optimization algorithms in discovering ideal solutions for complex challenges with limited resources often determines the problem complexity these methods can address. [...]

Particle physics using reactor antineutrinos
/ CHANDLER Collaboration
Nuclear reactors are uniquely powerful, abundant, and flavor-pure sources of antineutrinos that continue to play a vital role in the US neutrino physics program. The US reactor antineutrino physics community is a diverse interest group encompassing many detection technologies and many particle physics topics, including Standard Model and short-baseline oscillations, BSM physics searches, and reactor flux and spectrum modeling.

Model Independent Approach of the JUNO $^8$B Solar Neutrino Program
/ JUNO Collaboration
The physics potential of detecting $^8$B solar neutrinos is exploited at the Jiangmen Underground Neutrino Observatory (JUNO), in a model independent manner by using three distinct channels of the charged-current (CC), neutral-current (NC) and elastic scattering (ES) interactions. [...]
