Open AccessTop-philic ALP phenomenology at the LHC: the elusive mass-window
We study the LHC phenomenology of an Axion Like Particle (ALP) that couples only derivatively with the top quark at tree level. We inspect the radiatively induced couplings with the SM fermions and (gauge) bos...

Open AccessQuantum detection of new physics in top-quark pair production at the LHC
The recent observation of entanglement between top and anti-top quarks at the LHC opens the way to interpreting collider data with quantum information tools. In this work we investigate the relevance of quantu...

Open AccessPhenomenology of superheavy decaying dark matter from string theory
We study the phenomenology of superheavy decaying dark matter with mass around 1010 GeV which can arise in the low-energy limit of string compactifications. Generic features of string theory setups (such as high ...

Open AccessProbing new physics through entanglement in diboson production
Pair production of heavy vector bosons is a key process at colliders: it allows to test our understanding of the Standard Model and to explore the existence of new physics through precision measurements of pro...

Open AccessRenormalisation group effects on SMEFT interpretations of LHC data
We explore the impact of Renormalisation Group (RG) effects in the Standard Model Effective Field Theory (SMEFT) interpretations of LHC measurements. We implement the RG running and mixing for the Wilson coeff...

Open AccessThe Effective Vector Boson Approximation in high-energy muon collisions
Due to the inclination for forward gauge radiation, lepton colliders beyond a few TeV are effectively electroweak (EW) boson colliders, suggesting the treatment of EW bosons as constituents of high-energy lept...

Open AccessSingle top production in association with a WZ pair at the LHC in the SMEFT
We study single top quark production in association with a WZ pair at the LHC in the context of the Standard Model (SM) and the Standard Model Effective Field Theory (SMEFT). A significant advantage of tWZ compar...

Open AccessTop-philic heavy resonances in four-top final states and their EFT interpretation
With an expected rate of about one event per 100,000 top-quark pairs, four top-quark final states very rarely arise at the LHC. Though scarce, they offer a unique window onto top-quark compositeness, self-inte...
