Renormalisation group evolution effects on global SMEFT analyses

Journal of High Energy Physics
Global analyses in the Standard Model Effective Field Theory (SMEFT) framework serve as a tool to probe potential directions of new physics. To break degeneracies between the Wilson coefficients of the SMEFT, it is essential to combine observables from ...

On the Atomki nuclear anomaly after the MEG-II result

Journal of High Energy Physics
Recent experimental results from the Atomki collaboration have reported the observation of anomalous effects in Beryllium, Helium and Carbon nuclear transitions that could hint at physics beyond the Standard Model.

Automatizing the search for mass resonances using BumpNet

Journal of High Energy Physics
The search for resonant mass bumps in invariant-mass distributions remains a cornerstone strategy for uncovering Beyond the Standard Model (BSM) physics at the Large Hadron Collider (LHC). Traditional methods often rely on predefined functional forms and

Explanation of the excesses in associated di-photon production at 152 GeV in 2HDM

Journal of High Energy Physics
Statistically significant excesses exist at around 152 GeV in associated di-photon production (γγ + X) in the sidebands of SM Higgs analyses of ATLAS (using the full run-2 dataset).

Interference effects in resonant di-Higgs production at the LHC in the Higgs singlet extension

Journal of High Energy Physics
Interference effects are well founded from the quantum mechanical viewpoint and in principle cannot be ignored in realistic studies of New Physics scenarios.
