Higgs Boson Breakthroughs: Run 3 Data Reveals Exciting Discoveries at CERN (2025)

Higgs hunters are abuzz with excitement as the latest data from Run 3 arrives. The 15th Higgs Hunting workshop, held from July 15-17 at IJCLab in Orsay and LPNHE in Paris, brought together around 100 participants to delve into the most recent LHC Run 2 and 3 Higgs-boson results, alongside cutting-edge theoretical developments. One of the most anticipated presentations was from the CMS collaboration, who unveiled a novel search for Higgs boson coupling to charm quarks through its production in association with top-antitop pairs. This analysis, focusing on Higgs decays into charm-quark pairs, achieved a sensitivity comparable to the most stringent direct constraints on this elusive interaction. The CMS findings were complemented by new ATLAS analyses, which showcased the transformative potential of the vast Run 3 dataset. For instance, Run 3 data has significantly reduced uncertainties on the coupling of the Higgs boson to muons and Zγ by 30% and 38%, respectively. In the realm of di-Higgs production, the expected upper limit on the signal-strength modifier, measured exclusively in the bbγγ final state, has now surpassed the sensitivity of the combined Run 2 HH channels. This development is particularly promising, as it suggests that a signal could be detected before the upcoming long shutdown, scheduled from mid-2026 to the end of 2029. Juan Rojo from the Vrije Universiteit Amsterdam presented on parton distribution functions for Higgs processes at the LHC, while Thomas Gehrmann from the University of Zurich offered a comprehensive review of recent advancements in general Higgs theory. Mathieu Pellen from the University of Freiburg provided an insightful overview of vector-boson fusion, and Jose Santiago Perez from the University of Granada summarized the effective field theory framework. Oleksii Matsedonskyi from the University of Cambridge reviewed progress on electroweak phase transitions. Alfredo Urbano from INFN Rome delivered a thought-provoking "vision" talk, exploring the intricate relationship between Higgs physics and early-universe cosmology. Benjamin Fuks from LPTHE, Sorbonne University, presented a novel toponium model, reigniting interest in the enigmatic romance of top-quark pairs. After a relaxing cruise on the Seine, illuminated by the Olympic Cauldron, participants transitioned into the future during the European Strategy for Particle Physics session. Karl Jakobs from the University of Freiburg and the session speakers set the stage for lively discussions on the community's options, especially in the event that the FCC program, the clear plan A, is not realized. The next Higgs Hunting workshop is scheduled for September 16-18, 2026, in Orsay and Paris.
