Description

The 7th International Workshop on "Higgs as a Probe of New Physics" (HPNP2025) will be held at the University of Osaka (renamed in April 2025 from Osaka University). The aim of HPNP2025 is to bring together Higgs-related physicists from around the world to discuss the relationship between Higgs physics and models beyond the Standard Model. More details can be found on the workshop homepage: https://www-het.phys.sci.osaka-u.ac.jp/~nhwg/HPNP2025/
