Pileup and Infrared Radiation Annihilation (PIRANHA): a paradigm for continuous jet grooming [PDF]

Journal of High Energy Physics, 2023
Jet grooming is an important strategy for analyzing relativistic particle collisions in the presence of contaminating radiation. Most jet grooming techniques introduce hard cutoffs to remove soft radiation, leading to discontinuous behavior and ...

Cleaning Effect of Atmospheric-Plasma-Sprayed Y2O3 Coating Using Piranha Solution Based on Contamination Particle Measurement

Coatings, 2023
A Y2O3 coating was prepared using the atmospheric plasma spraying (APS) technique. On exposing the coating to CF4/O2/Ar plasma, a fluorine contamination layer (YOxFy) was formed, which was the main cause of process drift and contamination particle ...
