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…

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…

Deconstructing resonant Higgs pair production at the LHC: effects of coloured and neutral scalars in the NMSSM test case

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…

Unveiling ESSM Scalar Diquarks at the HL-LHC

Murad Ali, Shaaban Khalil, Stefano Moretti +2

We investigate the phenomenology of scalar diquarks with sub-TeV masses within the framework of the Supersymmetric Standard Model (ESSM) at the Large Hadron Collider (LHC…

Leptonic CP-violation in the sneutrino sector of the BLSSM with Inverse Seesaw

Arindam Basu, Amit Chakraborty, Yi Liu +2

We study CP violation (CPV) in the sneutrino sector within the B-L extension of the Minimal Supersymmetric Standard Model (BLSSM), wherein an inverse seesaw mechanism has been impl…
