Equivariant, safe and sensitive — graph networks for new physics (2024)
Journal Article
Bhardwaj, A., Englert, C., Naskar, W., Ngairangbam, V. S., & Spannowsky, M. (2024). Equivariant, safe and sensitive — graph networks for new physics. Journal of High Energy Physics, 2024(7), Article 245. https://doi.org/10.1007/jhep07%282024%29245

This study introduces a novel Graph Neural Network (GNN) architecture that leverages infrared and collinear (IRC) safety and equivariance to enhance the analysis of collider data for Beyond the Standard Model (BSM) discoveries. By integrating equivar... Read More about Equivariant, safe and sensitive — graph networks for new physics.

Dispelling the L myth for the High-Luminosity LHC (2024)
Journal Article
Belvedere, A., Englert, C., Kogler, R., & Spannowsky, M. (2024). Dispelling the L myth for the High-Luminosity LHC. The European Physical Journal C, 84(7), Article 715. https://doi.org/10.1140/epjc/s10052-024-13032-w

Extrapolations of sensitivity to new interactions and standard model parameters critically inform the programme at the Large Hadron Collider (LHC) and potential future collider cases. To this end, statistical considerations based on inclusive quantit... Read More about Dispelling the L myth for the High-Luminosity LHC.

Higgs boson off-shell measurements probe nonlinearities (2024)
Journal Article
Anisha, Englert, C., Kogler, R., & Spannowsky, M. (2024). Higgs boson off-shell measurements probe nonlinearities. Physical Review D, 109(9), Article 095033. https://doi.org/10.1103/physrevd.109.095033

The measurements of off-shell Higgs boson contributions in massive gauge boson pair production are known to probe its electroweak interactions across different energy scales. Often employed as an estimator of the Higgs boson width in restricted theor... Read More about Higgs boson off-shell measurements probe nonlinearities.

Evasive Higgs Boson Maneuvers at the LHC (2012)
Journal Article
Englert, C., Jaeckel, J., Re, E., & Spannowsky, M. (2012). Evasive Higgs Boson Maneuvers at the LHC. Physical Review D, Particles and fields, 85(3), Article 035008. https://doi.org/10.1103/physrevd.85.035008

Nonstandard decays of the Higgs boson produced at the Large Hadron Collider can lead to signatures which can easily be missed due to nonadapted trigger or search strategies. Keeping electroweak symmetry breaking standard model-like, we classify the p... Read More about Evasive Higgs Boson Maneuvers at the LHC.

Observing Strongly Interacting Vector Boson Systems at the CERN Large Hadron Collider (2009)
Journal Article
Englert, C., Jager, B., Worek, M., & Zeppenfeld, D. (2009). Observing Strongly Interacting Vector Boson Systems at the CERN Large Hadron Collider. Physical Review D, Particles and fields, 80(3), Article 035027. https://doi.org/10.1103/physrevd.80.035027

We explore the potential of the CERN Large Hadron Collider to access a strongly interacting electroweak symmetry breaking sector via weak boson scattering with W + W − j j , Z Z j j , and W ± Z j j final states. As examples of models with scalar or v... Read More about Observing Strongly Interacting Vector Boson Systems at the CERN Large Hadron Collider.
