Rare few-body decays of the Standard Model Higgs boson
/ D'Enterria Adan, David (CERN) ; Le, Van Dung (Vietnam National University (VN))
We present a survey of rare and exclusive few-body decays of the standard model (SM) Higgs boson, defined as those into two to four final particles with branching fractions $\mathcal{B}\lesssim 10^{-5}$. Studies of such decays can be exploited to constrain Yukawa couplings of quarks and leptons, probe flavour-changing Higgs decays, estimate backgrounds for exotic Higgs decays into beyond-SM particles, and/or confirm quantum chromodynamics factorization with small nonperturbative corrections [...]

Parametrisation and dictionary for CP violating Higgs interactions
/ Barducci, Daniele (Universita & INFN Pisa (IT)) ; Giardino, Pier Paolo (CERN) ; Forslund, Matthew (C. N. Yang Institute for Theoretical Physics, Stony Brook University, Stony Brook, NY, 11794, USA High Energy Theory Group, Physics Department, Brookhaven National Laboratory, Upton, NY 11973, USA) ; Fuentes Zamoro, Marta (Departamento de Física Teórica and Instituto de Física Teórica UAM/CSIC, Universidad Autónoma de Madrid, Cantoblanco, 28049, Madrid, Spain)
Searches for charge-parity (CP) violating interactions of the Standard Model (SM) Higgs boson are a key priority of the LHC physics program. Experimental results from ATLAS and CMS are often reinterpreted within a variety of theoretical parametrisations, the most commonly used being the Higgs basis, $\kappa$'s and angles, CP fractions and effective field theories (EFT) such as the SMEFT and the Higgs EFT. [...]

Higgs production via vector-boson fusion at the LHC
/ Barone, Gaetano (Brown University (US)) ; Chen, Jiayi (Simon Fraser University (CA)) ; Dolganov, Nikita (Simon Fraser University (CA)) ; Ferrario Ravasio, Silvia (CERN) ; Haddad, Yacine (Northeastern University (US)) ; Hoche, Stefan (Fermilab) ; Jager, Barbara (Institute for Theoretical Physics, University of Tübingen) ; Karlberg, Alexander (CERN) ; Mück, Alexander (Institute for Theoretical Particle Physics and Cosmology, RWTH Aachen University) ; Pellen, Mathieu (University of Freiburg (DE)) et al.
In this article, we summarise the recent experimental measurements and theoretical work on Higgs boson production via vector-boson fusion at the LHC. Along with this, we provide state-of-the-art predictions at fixed order as well as with parton-shower corrections within the Standard Model at 13.6 TeV. [...]
