We here report on the progress of the HHH Workshop, that took place in Dubrovnik in July 2023. After the discovery of a particle that complies with the properties of the Higgs boson of the Standard Model, all SM parameters are in principle determined. [...]

ALP-ine quests at the LHC: hunting axion-like particles via peaks and dips in $t \bar{t}$ production
/ Anuar, Afiq (CERN) ; Biekötter, Anke (Mainz U., Inst. Phys. ; U. Mainz, PRISMA) ; Biekötter, Thomas (KIT, Karlsruhe, TP) ; Grohsjean, Alexander (Hamburg U.) ; Heinemeyer, Sven (Madrid, IFT) ; Jeppe, Laurids (DESY) ; Schwanenberger, Christian (Hamburg U. ; DESY) ; Weiglein, Georg (DESY ; Hamburg U., Inst. Theor. Phys. II)
We present an analysis of the sensitivity of current and future LHC searches for new spin-0 particles in top-anti-top-quark ($t\bar{t}$) final states, focusing on generic axion-like particles (ALPs) that are coupled to top quarks and gluons. [...]

Interdependence of the new "MUON G-2" Result and the $W$-Boson Mass
/ Bagnaschi, Emanuele (CERN) ; Chakraborti, Manimala (Warsaw, Copernicus Astron. Ctr.) ; Heinemeyer, Sven (Madrid, IFT) ; Saha, Ipsita (Tokyo U., IPMU) ; Weiglein, Georg (DESY ; Hamburg U.)
The electroweak (EW) sector of the Minimal Supersymmetric extension of the Standard Model (MSSM), assuming the lightest neutralino as Dark Matter (DM) candidate, can account for a variety of experimental results. In particular it can account for the discrepancy between the experimental result for the anomalous magnetic moment of the muon, $(g-2)_{\mu}$, and its Standard Model (SM) prediction. [...]

Constraining the ${\mathcal {C}}{\mathcal {P}}$ structure of Higgs-fermion couplings with a global LHC fit, the electron EDM and baryogenesis

CP violation in the Higgs couplings to fermions is an intriguing, but not yet extensively explored possibility. We use inclusive and differential LHC Higgs boson measurements to fit the CP structure of the Higgs Yukawa couplings. [...]

Simple and statistically sound recommendations for analysing physical theories

Physical theories that depend on many parameters or are tested against data from many different experiments pose unique challenges to statistical inference. Many models in particle physics, astrophysics and cosmology fall into one or both of these categories. [...]

Higgs-mass predictions in the MSSM and beyond
/ Slavich, P. (ed.) (Paris, LPTHE) ; Heinemeyer, S. (ed.) (Madrid, Autonoma U. ; Cantabria Inst. of Phys.) ; Bagnaschi, E. (PSI, Villigen) ; Bahl, H. (DESY) ; Goodsell, M.

(Korea U. ; Cornell U., LEPP ; Toronto U.) et al.
Predictions for the Higgs masses are a distinctive feature of supersymmetric extensions of the Standard Model, where they play a crucial role in constraining the parameter space. The discovery of a Higgs boson and the remarkably precise measurement of its mass at the LHC have spurred new efforts aimed at improving the accuracy of the theoretical predictions for the Higgs masses in supersymmetric models.

Indirect $\mathcal{CP}$ probes of the Higgs-top-quark interaction: current LHC constraints and future opportunities
/ Bahl, Henning (DESY) ; Bechtle, Philip (Bonn U.) ; Heinemeyer, Sven (CSIC, Madrid ; Cantabria Inst. of Phys.) ; Katzy, Judith (DESY) ; Klingl, Tobias (Bonn U.) ; Peters, Krisztian (DESY) ; Saimpert, Matthias (CERN) ; Stefaniak, Tim (DESY) ; Weiglein, Georg (DESY)
The $\mathcal{CP}$ structure of the Higgs boson in its coupling to the particles of the Standard Model is amongst the most important Higgs boson properties which have not yet been constrained with high precision. In this study, all relevant inclusive and differential Higgs boson measurements from the ATLAS and CMS experiments are used to constrain the $\mathcal{CP}$-nature of the top-Yukawa interaction. [...]
