Interference Effects in Resonant Standard Model di-Higgs Production and Decay into Final States: the Role of Machine Learning Analysis

A. Hammad, S. Moretti, A. P. Przybyl +1

The final state with four -quarks has generally the largest event rate in Standard Model (SM)-like Higgs () pair production, but also the largest backgrounds. We stu…

Freeze-in and Freeze-out in a Right-Handed Neutrino Extended MSSM with a Seesaw Mechanism

Tushar Gupta, Matti Heikinheimo, Katri Huitu +1

We investigate the possibility of saturating the relic density bound with light Higgsinos. When the minimal supersymmetric Standard Model is extended with right-handed neutrino sup…

Stefano Moretti, Luca Panizzi, Jörgen Sjölin +1

We study resonant production of pairs of Standard Model (SM)-like Higgs bosons, in the presence of new neutral Higgs states together with new coloured scalars (stops or sbottoms) i…

Constraints on the boson from IceCube searches for non-standard interactions of neutrinos

Rikard Enberg, Yaşar Hiçyılmaz, Stefano Moretti +2

We explain the ATOMKI anomaly with a very light state that features non-anomalous and non-flavour-universal vector and axial-vector couplings to all leptons. This comes f…

Exploring high scale seesaw models through a supersymmetric portal

Yi Liu, Stefano Moretti, Harri Waltari

The seesaw scale is a priori unknown. If the seesaw scale is low, one may directly look for the new particles predicted by seesaw models. If the seesaw scale is high, such an appro…

TeV-scale leptoquark searches at the LHC and their ESSM Interpretation

Murad Ali, Shaaban Khalil, Stefano Moretti +4

We perform a model-independent search for leptoquarks (LQs) at the Large Hadron Collider through their pair-production and subsequent decay into intermediate states. W…

Deconstructing squark contributions to di-Higgs production at the LHC

Stefano Moretti, Luca Panizzi, Jörgen Sjölin +1

We present a novel approach to the study of di-Higgs production via gluon-gluon fusion at the LHC. The relevant Feynman diagrams involving two Standard Model-like Higgs bosons …

Exploring neutrino physics through sneutrinos

Stefano Moretti, Claire Shepherd-Themistocleous, Harri Waltari

Supersymmetry relates neutrinos with their superpartners, sneutrinos. Unlike neutrinos, sneutrinos may decay visibly in colliders. We discuss how we could get information from neut…
