Dr. Zhiyuan Wang talks about: "The R-matrix theory of parastatistics"

R-parastatistics [1] is an exotic type of particle exchange statistics beyond fermions and bosons
that is consistently dened in any dimension. This talk presents an updated account of this research
direction, including recent progress and future perspectives. I begin by reviewing the main results
from Ref. [1], including the foundation, physical realization, and a proposed application in secret
communication [2]. I then discuss several new developments, including generalized symmetries of
paraparticle systems, Bogoliubov-type Hamiltonians that describe \paraparticle superconductors",
and R-quantized relativistic eld theories that may model elementary paraparticles. I conclude with
a discussion of open questions and future directions.

Dr. Vitaly Wirthl talks about: "Standard Model test below 1ppt with the 2S-6P transition frequency measurement in atomic hydrogen"

Quantum electrodynamics (QED) forms the basis for all other quantum field theories, upon which the Standard Model of particle physics is constructed. Due to the simplicity of the hydrogen atom, its energy levels can be precisely calculated from bound-state QED and confronted with the experiment. In this talk I will present our recent 2S-6P transition frequency measurement in atomic hydrogen, which provides a theory test with an accuracy below 1 ppt, making it one of the most precise tests of the Standard Model.
