9. Effect of dimension-6 operators on Higgs VBF

Albert Zhou (Cornell University (US))

We examine the effects of dimension-6 SMEFT operators on Higgs production in the vector boson fusion channel through the Simplified Template Cross Section (STXS) framework. After reweighting MadGraph generated samples, we extract quadratic dependencies of the two bin yields as a function of Wilson Coefficients. We then perform a chi-squared fit on CMS observed data to constrain the Wilson Coefficients.

7. Effective Field Theories in Cosmology

Mikhail Ivanov (MIT)

I will review the application of Effective Field Theories to Cosmology and share some recent results on tests of new physics with EFT tools

17. Efficient EFT Monte Carlo with differentiable matrix elements

Jonathan Samudio (Baylor University (US))

EFT sample generation for physics analysis has largely relied on MadGraph’s traditional reweight operation. This is limited in its effectiveness by computational bottlenecks, and the statistical power is challenged by the choice of initial sampling point. We have developed a new reweight plugin for MadGraph which is built on MadJax, a plugin enabling differential matrix elements. By utilizing...

2. Energy enhancements and cutoffs in EFT

Benoit Assi (Fermilab)

SMEFT interpretations at the LHC typically rely on a truncation at linear dimension six, while experimental sensitivity is increasingly driven by high-energy regions where contributions grow with energy and higher-dimensional effects become important. I will present a framework that addresses both issues. First, we introduce an energy-based power counting that organizes SMEFT contributions...

20. Matrix-element method for ttH(bb) EFT analysis

Adrian-Antonio Petre (ETH Zurich (CH))

The Matrix Element Method (MEM) is a well motivated multivariate technique to access the likelihood of a reconstructed event given a hypothesis. It offers optimal statistical power for hypothesis testing in particle physics, but it is limited by the computation of the intensive multi-dimensional integrals required to model detector and theory effects. We present a novel approach that addresses...

4. Metrics and Compression for Quantum Observables for EFT

Heshy Roskes (Johns Hopkins University (US))

Advances in machine learning have expanded our ability to construct powerful observables for collider measurements by enabling approximation of analytical matrix elements that are impractical to compute for complex processes. However, there is no rigorous metric for optimality when quantum interference is important. Standard tools often fail when probability distributions change sign, as it...

16. Odd Physics Off the Diagonal: Constraining CP-violating SMEFT with Quantum Information Techniques

Patrick Dougan (Southern Methodist University (US))

New sources of charge-parity (CP) violation beyond those described in the Standard Model (SM) are required to explain the observed matter--antimatter asymmetry of the Universe. The Standard Model Effective Field Theory (SMEFT) provides a framework to introduce additional electroweak sources of CP-odd physics in a model-independent manner. However, these CP-violating signatures are mostly...

10. Probing SMEFT Effects in Polarized WZ Production at the LHC

Maryam Bayat Makou (Southern Methodist University (US))

Diboson production at the LHC provides a powerful probe of the electroweak sector and its extensions within the Standard Model Effective Field Theory (SMEFT). We present a study of the interplay between dimension-6 operators and gauge boson polarization in $WZ \rightarrow 3\ell$ production at $\sqrt{s}=13$ TeV.

The analysis is based on dedicated Monte Carlo samples generated with...

6. Quantifying EFT Uncertainties in LHC Searches

Teng Ma

This talk presents an EFT analysis procedure that gives model-independent constraints even if the new physics cutoff (M) is low. The method treats the uncertainties from higher dimensional operators as nuisance parameters which are marginalized in the analysis. Unlike normal EFT analyses, this leads to conservative constraints which are consistently weaker than UV complete models with new...

5. Quantum Information Meets Collider Physics

dorival Gonçalves (Oklahoma State University)

Collider experiments provide direct access to the quantum dynamics of fundamental interactions at the highest accessible energies. By interpreting scattering processes as coherent superpositions of polarized amplitudes, quantum tomography enables reconstruction of spin density matrices and direct probes of entanglement and symmetry properties. In this talk, I will review recent progress in...

11. Search for new physics in triple boson production in proton-proton collisions at √s = 13 TeV using the effective field theory approach

Saptaparna Bhattacharya (Southern Methodist University (US))

We will present a new CMS result on the search for new physics (NP) in triboson processes, interpreted within the framework of an Effective Field Theory (EFT). This comprehensive analysis covers ten final states comprising boosted jets and leptons, notably including the first exploration of hadronic and tau-based final states. The analysis utilizes thirty-seven kinematic bins tuned for each...

18. Search for new physics using top quark pairs produced in association with a boosted Z or Higgs boson in effective field theory with symmetry preserving attention networks

Jonathan Samudio (Baylor University (US))

Standard Model effective field theory (EFT) provides a broad search framework for new physics which may exist at collision energies beyond the current reach of the LHC. We present the current status of the analysis searching for EFT effects in pp collisions where a top quark pair is produced in association with a boosted Z or Higgs boson, and the Z or Higgs decays to a bb pair. This process is...

42. The Tangled Dance of Higgs Boson Decays: Quantum State Studies in H -> ZZ

Zhiyuan Huang (Johns Hopkins University (US))

The study of spin correlations in the Higgs boson decay into two Z bosons provides a powerful approach to probing the Higgs boson's quantum state and investigating its interactions with Standard Model particles. We present the first study of quantum entanglement in Higgs boson decays. Data from the CMS Run 2 and Run 3 datasets are used, and the spin polarization density matrix for Higgs boson...

3. Toward Machine-Learned Representations of SMEFT Deformations in Collider Observables

Supratim Das Bakshi

We discuss an AI-assisted inference pipeline that learns the mapping between Wilson coefficient deformations and collider observables directly from simulated event data. This approach constructs physics-informed latent representations of SMEFT parameter space using neural architectures trained on differential cross sections and kinematic distributions. These learned embeddings enable efficient...

19. Unbinned multidimensional scale factors for SBI

Davide Valsecchi (ETH Zurich (CH))

Precision detector calibration is a fundamental prerequisite for deploying realistic Simulation-Based Inference (SBI) in high-energy physics, particularly for maximizing sensitivity in Effective Field Theory (EFT) measurements. Recent advances in probabilistic machine learning enable unbinned likelihood fits that extract continuous, multidimensional calibrations simultaneously. This talk...
