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.

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

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). [...]

Compilation of low-energy constraints on 4-fermion operators in the SMEFT
/ Falkowski, Adam (Orsay, LPT) ; González-Alonso, Martín (Lyon, IPN ; CERN) ; Mimouni, Kin (ITPP, Lausanne)
We compile information from low-energy observables sensitive to flavor-conserving 4-fermion operators with two or four leptons. Our analysis includes data from e+e- colliders, neutrino scattering on electron or nucleon targets, atomic parity violation, parity-violating electron scattering, and the decay of pions, neutrons, nuclei and tau leptons.

On the Validity of the Effective Field Theory Approach to SM Precision Tests
/ Contino, Roberto (ITPP, Lausanne ; CERN) ; Falkowski, Adam (Orsay, LPT) ; Goertz, Florian (CERN) ; Grojean, Christophe (DESY) ; Riva, Francesco (CERN)
We discuss the conditions for an effective field theory (EFT) to give an adequate low-energy description of an underlying physics beyond the Standard Model (SM). Starting from the EFT where the SM is extended by dimension-6 operators, experimental data can be used without further assumptions to measure (or set limits on) the EFT parameters. [...]
