Threshold improved $ZH$ production at the LHC
/ Samanta, Kajal (Institute for Particle Physics Phenomenology, Durham University, Durham DH1 3LE, United Kingdom) ; Das, Goutam (Institut für Theoretische Teilchenphysik und Kosmologie, RWTH Aachen University, D-52056 Aachen, Germany) ; Dey, Chinmoy (Department of Physics, Indian Institute of Technology Guwahati, Guwahati-781039, Assam, India and Theoretical Physics Division, Physical Research Laboratory, Navrangpura, Ahmedabad 380009, India) ; Kumar, M C (Department of Physics, Indian Institute of Technology Guwahati, Guwahati-781039, Assam, India)
We present precise theoretical results for the $ZH$ production cross section and invariant mass distribution at the Large Hadron Collider (LHC) taking into account the effects of soft gluons. We improve both quark-initiated and gluon-initiated subprocesses through threshold resummation within the QCD framework and present combined results relevant for 13.6 TeV LHC [...]

We present state-of-the-art predictions for the inclusive cross section of gluon-initiated $ZH$ production, following the recommendations of the LHC Higgs Working Group. In particular, we include NLO QCD corrections, where the virtual corrections are obtained from the combination of a forward expansion and a high-energy expansion, and the real corrections are exact.

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

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. [...]
