The Higgs self-couplings remain only weakly constrained by current Large Hadron Collider (LHC) measurements, leaving ample room for physics beyond the Standard Model that could modify the structure of the Higgs potential. Multi-Higgs production processes provide a particularly sensitive probe of deviations in both the trilinear and quartic Higgs self-couplings. [...]

Charged Higgs Pairs at the LHC: A NLO Analysis
/ Spira, Michael (Paul Scherrer Institute (CH)) ; Biermann, Lisa (Paul Scherrer Institute) ; Ita, Harald (Paul Scherrer Institute, UZH) ; Yedelkina, Yelizaveta (Paul Scherrer Institute) ; Rusetski, Irina (Paul Scherrer Institute, Bern University) ; Ahmed, Mohamed (Paul Scherrer Institute)
Charged Higgs-boson pair production at hadron colliders yields information about the trilinear couplings involving charged Higgs fields in extensions of the Standard Model (SM). We consider the two-Higgs doublet model (2HDM) extension and obtain next-to-leading order QCD predictions for the charged-Higgs pair production ($H^+H^-$ production). [...]

Impact of Higgs-Boson measurements on SMEFT Fits
/ De Blas Mateo, Jorge (Universidad de Granada (ES)) ; Goncalves, Angelica (Florida State University (USA)) ; Miralles, Victor (University of Manchester (UK)) ; Reina, Laura (Florida State University (USA)) ; Silvestrini, Luca (Sapienza Universita e INFN, Roma I (IT)) ; Valli, Mauro (Sapienza Universita and INFN, Roma I (IT))
We present current bounds on SMEFT operators that are mainly constrained by Higgs-boson observables, under different assumptions for the flavour structure of the UV theory. We investigate how the accuracy reached through a dedicated Higgs-boson precision physics program is starting to have a major impact in setting a lower bound on the scale of new physics, and we discuss the relevance of considering the scale evolution of the SMEFT coefficients in this context.

State-of-the-art electroweak Higgs boson pair production in association with two jets at the LHC in the Standard Model and beyond

We present a systematic comparison of two state-of-the-art tools for the simulation of Higgs-pair production via vector boson fusion (VBF) as implemented in GoSam+Whizard and the POWHEG-BOX. Cross sections and distributions are provided within the Standard Model and beyond within scenarios typical for experimental analyses and for a range of energies of relevance to the LHC and its upcoming high luminosity phase.

We present new state-of-the-art predictions for Standard Model Higgs boson production in association with a bottom-quark pair ($b\bar bH$). Updated cross sections are computed in accordance with the recommendations of the LHC Higgs Working Group, including the use of the PDF4LHC21 set of parton distribution functions, with a center-of-mass energy of 13.6 TeV.

The inclusive Higgs boson cross-section in gluon-gluon fusion in soft-virtual approximation at fourth order in QCD
/ Das, Goutam (RWTH Aachen University) ; Moch, Sven-Olaf (Hamburg University (DE))
We present precise results for the inclusive Higgs boson cross-section in gluon-gluon fusion at the LHC considering state-of-the-art fourth-order results in perturbative QCD arising from the dominant soft and virtual gluon emissions. Utilizing four-loop QCD results for the gluon-form factor, the splitting function and related anomalous dimen- sions, we study the effects of threshold enhanced soft gluon emissions and estimate their impact on the total cross-section at the fourth order.

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 [...]
