Partonic spin correlations in Higgs boson decays provide a novel opportunity to probe the CP structure of the Higgs--gluon coupling at future lepton colliders. Translating this physics potential into a realistic measurement requires the identification of different gluon splitting modes, whose contributions can otherwise largely cancel in inclusive observables. In this work, we take a step...

High-energy physics experiments require increasingly high-speed data transmission in front-end readout systems. Based on our prior designs and measurements, the 10-Gbps NRZ transmission is approaching the bandwidth limit of the 55-nm CMOS process. Consequently, PAM4 transmission technology, which doubles the data rate within the same analog bandwidth, presents an attractive alternative.

Yttrium-doped barium fluoride (BaF2:Y) is attractive for high-rate radiation detection because Y doping suppresses the slow self-trapped-exciton emission while retaining the ultrafast core-valence luminescence of BaF2. Its practical use, however, requires both scalable crystal growth and control of position-dependent light collection. We address these requirements through two complementary...
