第十二届中国 LHC 物理会议（CLHCP2026）

"A direct measurement of the Higgs-top Yukawa coupling is essential for testing the Standard Model and probing new physics. The associated production of a Higgs boson with a top-quark pair (ttH) provides the only direct access to this coupling at the LHC, with the multilepton channel regarded as the ‘golden channel’ for ttH measurement owing to its relatively high signal-to-background ratio...

In this report, we will introduce the current status of the Flex Tail (FT) and High Voltage Power Supply (HVPS) systems. In the ATLAS High Granularity Timing Detector (HGTD) project , the FTs are designed for the connection between detector module and Peripheral Electronics Board (PEB). According to different location in the detector sector, there are so many kinds of FTs with different...

Semiconductor detectors, owing to their low material budget, precise spatial resolution, and mature fabrication processes, are widely used in the tracking systems of large-scale spectrometers. Compared with conventional strips or hybrid chips, MAPS detectors use highly integrated commercial semiconductor processes, enabling complex front-end electronics while maintaining low cost in...

"The increasing level of front-end integration in particle detectors has placed new requirements on powering systems, particularly in terms of material budget, power distribution, and system scalability. Serial powering, based on a constant-current scheme with shunt-LDO regulators (SLDO), has been an attractive solution for large-scale detector systems and future collider upgrades.
