The 22th Meeting on Off-Shell Science (, formally, Meeting on Dressed Photon and Off-Shell Science Theories) was held on February 14, 2022 (On line meeting).

The 22th Meeting on Off-Shell Science (, formally, Meeting on Dressed Photon and Off-Shell Science Theories) was held on February 14, 2022 (On line meeting). Twelve experts joined the meeting. Interesting topics on the mathematical bases of the quantum walk model for describing dressed photon phenomena, high-speed computation by using the network quantum walk model, and numerical simulations of DP generation efficiency, were presented. Intensive discussions on these topics were made.
