Author

Belvedere, Alberto, Bhattacharya, Saptaparna, Boldrini, Giacomo, Chatterjee, Suman, Calandri, Alessandro, Cruz, Sergio Sánchez, Dickinson, Jennet, Glessgen, Franz J., Goldouzian, Reza, Grohsjean, Alexander, Jeppe, Laurids, Knight, Charlotte, Mattelaer, Olivier, Mohrman, Kelci, Nelson, Hannah, Perovic, Vasilije, Presilla, Matteo, Schöfbeck, Robert, and Smith, Nick

Abstract

This note gives an overview of the tools for predicting expectations in the Standard Model effective field theory (SMEFT) at the tree level and one loop available through event generators. Methods of event reweighting, the separate simulation of squared matrix elements, and the simulation of the full SMEFT process are compared in terms of statistical efficacy and potential biases., Comment: 40 pages, 23 figures.

Abstract

We introduce the usage of equivariant neural networks in the search for violations of the charge-parity ($\textit{CP}$) symmetry in particle interactions at the CERN Large Hadron Collider. We design neural networks that take as inputs kinematic information of recorded events and that transform equivariantly under the a symmetry group related to the $\textit{CP}$ transformation. We show that this algorithm allows to define observables reflecting the properties of the $\textit{CP}$ symmetry, showcasing its performance in several reference processes in top quark and electroweak physics. Imposing equivariance as an inductive bias in the algorithm improves the numerical convergence properties with respect to other methods that do not rely on equivariance and allows to construct optimal observables that significantly improve the state-of-the-art methodology in the searches considered.

3. A rotation-equivariant graph neural network for learning hadronic SMEFT effects

Abstract

We introduce a graph neural network architecture designed to extract novel phenomena in the Standard Model Effective Field Theory (SMEFT) context from LHC collision data. The proposed infrared- and collinear-safe architecture is sensitive to the angular orientation of radiation patterns in jets from hadronic decays of highly energetic massive particles. Equivariance with respect to rotations around the jet axis allows for extracting the information on the angular orientation decoupled from the jet substructure. We demonstrate the robustness of the approach and its potential for future probes of the SMEFT at the LHC through toy studies and with realistic event simulations of the WZ process in the semileptonic decay channel., Comment: 9 pages, 5 figures

4. Search for EFT in associated top production

Author

Abstract

A search for new physics in top quark production with additional final-state leptons is performed with 138 $\mathrm{fb}^{-1}$ of proton-proton collision data at $\sqrt{s}$ = 13 TeV. We use the framework of effective field theory to parametrize potential new physics effects in terms of 26 dimension-six EFT operators. The data are divided into several categories based on lepton multiplicity, total lepton charge, jet multiplicities, and b-tagged jet multiplicities. Kinematic variables are used to extract limits simultaneously on the associated set of Wilson coefficients., Comment: 6 pages, 2 figures.

22. Measurement of tW the production cross-section at 13 TeV with CMS

Author

Subjects
High Energy Physics - Experiment
Abstract

The inclusive cross-section for tW production in proton-proton collisions at $\sqrt{s} = 13$ TeV is measured with a dataset corresponding to an integrated luminosity of 35.9 fb$^{-1}$ collected by the CMS experiment. The measurement is performed in events with one electron and one muon, and exploits kinematic differences between the signal and the dominating $t\bar{t}$ background through the use of multivariate discriminants designed to separate the two processes. The measured cross-section of $\sigma = 63.1 \pm 1.8~({\rm stat}) \pm 6.0~({\rm syst}) \pm 2.1~({\rm lumi})$ pb is in agreement with standard model expectations.

Abstract

A set of measurements of top quark pair and single top quark production in association with standard model (SM) bosons performed by the CMS and ATLAS Collaborations is presented. The consistency of these results among themselves and with the SM prediction is discussed. The latest results on four top quark production are also shown.

31. Searches for strong production of SUSY particles with two opposite-sign same-flavor leptons at CMS

Author

Cruz, Sergio Sánchez

Subjects
High Energy Physics - Experiment
Abstract

A search is presented for physics beyond the standard model in events with two opposite-sign, same-flavor leptons, jets and missing transverse momentum in the final state. The search is performed in a dataset of 35.9 $\mathrm{fb}^{-1}$ of $\sqrt{s} = $ 13 TeV pp collisions recorded by the CMS experiment in the year 2016. The search targets models in which a colored particle is produced. Models are considered, in which a kinematic edge is observed in the dilepton invariant mass distribution and models in which a Z boson arises in the decay chain of the SUSY particles. Such searches have been performed in 8 TeV pp collisions as well as 13 TeV collisions. This version of the search adds additional event categories as well as improved background estimation procedures substantially increasing the sensitivity of the search. The results are interpreted in the context of simplified models of Supersymmetry.
