Higgs boson mass and thermal wino dark matter from Starobinsky supergravity with the MSSM
Daniel Frolovsky, Alexander Belyaev, Sergei V. Ketov
We propose a framework connecting cosmic microwave background (CMB) observables with high-energy particle phenomenology, based on Starobinsky supergravity coupled to the Minimal Su…

Minimal Scale-Invariant Dark Matter
Alexander Belyaev, Roman Pasechnik, Rishav Roshan +1
We study the minimal classically scale-invariant extension of the Standard Model, containing a single -stabilised real scalar singlet whose mass is not an independent…

Novel Multilepton Signatures from the Fermionic Portal to Vector Dark Matter
Alexander Belyaev, Manimala Chakraborti, Claire Shepherd-Themistocleous +1
We perform a collider study of a novel multilepton signature arising from pair production of heavy vector-like leptons followed by cascade decays through a dark sector. In the muon…
