Automated Extraction of Collins-Soper Kernel from Lattice QCD using An Autonomous AI Physicist System

This paper demonstrates that the autonomous AI system PhysMaster can fully automate the complex, multi-step extraction of the Collins-Soper kernel from Lattice QCD data, reducing the workflow duration from months to hours while achieving precision consistent with state-of-the-art traditional methods and stabilizing signals at large transverse separations.

Pseudoscalar contributions to Zh production at the LHC at 95 GeV and above

This paper analyzes pseudoscalar contributions to ZhZh production in extended scalar sector models, finding that while a 95 GeV pseudoscalar yields negligible effects, heavier pseudoscalars (100–1000 GeV) can produce cross-sections exceeding current LHC limits, thereby constraining the parameter spaces of the Two Higgs Doublet Model and its singlet extension.

Dynamically assisted Schwinger pair production in differently polarized electric fields with the frequency chirping

This paper investigates how frequency chirps and field polarization influence dynamically assisted electron-positron pair production within the Dirac-Heisenberg-Wigner formalism, revealing that chirps significantly enhance pair yields through interference effects while simultaneously reducing the system's sensitivity to polarization, thereby offering a pathway for optimizing particle generation.
