Off-shell Higgs Interpretations Task Force : Models and Effective Field Theories Subgroup Report
/ Azatov, Aleksandr (SISSA, Trieste ; INFN, Trieste) ; Falkowski, Adam (U. Paris-Saclay ; CNRS, France ; Paris, IN2P3 ; IJCLab, Orsay) ; Gritsan, Andrei V. (Johns Hopkins U.) ; Grojean, Christophe (DESY ; Humboldt U., Berlin) ; Kauer, Nikolas (Royal Holloway, U. of London) ; Salvioni, Ennio (Padua U. ; INFN, Padua) ; Thomas, Marion (Manchester U.) ; Vryonidou, Eleni (Manchester U.) ; Kang, Lucas (Johns Hopkins U.) ; de Blas, Jorge (CAFPE, Granada) et al.
This report presents the results of the Models and Effective Field Theories Subgroup of the Off-Shell Interpretations Task Force in the LHC Higgs Working Group. The main goal of the subgroup was to discuss and advance the potential impact of off-shell Higgs measurements on searches for BSM physics carried out in the EFT framework or as benchmark model studies.

Truncation, validity, uncertainties
/ Brivio, Ilaria (Heidelberg U. ; Zurich U.) ; Dawson, Sally (Brookhaven) ; de Blas, Jorge (CAFPE, Granada ; Granada U., Theor. Phys. Astrophys. ; CERN) ; Durieux, Gauthier (CERN) ; Petrucciani, Giovanni (CERN) ; Savard, Pierre (Toronto U.) ; Berger, Nicolas (Annecy, LAPP) ; Contino, Roberto (Rome U.) ; Degrande, Céline (Louvain U., CP3) ; Falkowski, Adam (IJCLab, Orsay) et al.
The truncation of the standard-model effective field theory, its validity and the associated uncertainties have been discussed in meetings of the LHC EFT WG. Proposals were made by participants to address these issues. [...]

EFT at FASER$\nu$
/ Falkowski, Adam (IJCLab, Orsay) ; González-Alonso, Martín (Valencia U.) ; Kopp, Joachim (CERN ; U. Mainz, PRISMA) ; Soreq, Yotam (CERN ; Technion) ; Tabrizi, Zahra (Virginia Tech.)
We investigate the sensitivity of the FASER$\nu$ detector to new physics in the form of non-standard neutrino interactions. FASER$\nu$, which has recently been installed 480 m downstream of the ATLAS interaction point, will for the first time study interactions of multi-TeV neutrinos from a controlled source. [...]

Light quark Yukawas in triboson final states
/ Falkowski, Adam (IJCLab, Orsay) ; Ganguly, Sanmay (Weizmann Inst.) ; Gras, Phillippe (IRFU, Saclay) ; No, Jose Miguel (Madrid, Autonoma U.) ; Tobioka, Kohsaku (Florida State U. ; KEK, Tsukuba) ; Vignaroli, Natascia (Pisa U. ; INFN, Pisa) ; You, Tevong (CERN ; Cambridge U., DAMTP)
Triple heavy vector boson production, $p p \to VVV$$(V = W, Z)$, has recently been observed for the first time. We propose that precision measurements of this process provide an excellent probe of the first generation light quark Yukawa couplings. [...]

The CKM parameters in the SMEFT
/ Descotes-Genon, Sébastien (Orsay, LPT) ; Falkowski, Adam (Orsay, LPT) ; Fedele, Marco (ICC, Barcelona U.) ; González-Alonso, Martín (CERN) ; Virto, Javier (Munich, Tech. U. ; MIT, Cambridge, CTP)
The extraction of the Cabibbo-Kobayashi-Maskawa (CKM) matrix from flavour observables can be affected by physics beyond the Standard Model (SM). We provide a general roadmap to take this into account, which we apply to the case of the Standard Model Effective Field Theory (SMEFT). [...]

Report from Working Group 4 : Opportunities in Flavour Physics at the HL-LHC and HE-LHC
/ Cerri, A. (Sussex U.) ; Gligorov, V.V. (Paris U., VI-VII) ; Malvezzi, S. (INFN, Milan Bicocca) ; Martin Camalich, J. (Laguna U., Tenerife ; IAC, La Laguna) ; Zupan, J. (Cincinnati U.) ; Akar, S. (Cincinnati U.) ; Alimena, J. (Ohio State U.) ; Allanach, B.C. (Cambridge U., DAMTP) ; Altmannshofer, W. (UC, Santa Cruz, Inst. Part. Phys.) ; Anderlini, L. (INFN, Florence) et al.
Motivated by the success of the flavour physics programme carried out over the last decade at the Large Hadron Collider (LHC), we characterize in detail the physics potential of its High-Luminosity and High-Energy upgrades in this domain of physics. We document the extraordinary breadth of the HL/HE-LHC programme enabled by a putative Upgrade II of the dedicated flavour physics experiment LHCb and the evolution of the established flavour physics role of the ATLAS and CMS general purpose experiments.
