The Supersymmetric R-Parity Violating Dine-Fischler-Srednicki-Zhitnitsky Axion Model

Stefano Colucci, Herbi K. Dreiner, Lorenzo Ubaldi

We propose a complete R-parity violating supersymmetric model with baryon triality that contains a Dine-Fischler-Srednicki-Zhitnitsky axion chiral superfield. We parametrize supers…

Radiative corrections to vectorlike portal dark matter

Stefano Colucci, Federica Giacchino, Michel H. G. Tytgat +1

A massive real scalar dark matter particle can couple to Standard Model leptons or quarks through a vector-like fermionic mediator , a scenario known as the Vector-like port…

Top-philic Vector-Like Portal to Scalar Dark Matter

Stefano Colucci, Benjamin Fuks, Federica Giacchino +3

We investigate the phenomenology of scalar singlet dark matter candidates that couple dominantly to the Standard Model via a Yukawa interaction with the top quark and a colored vec…

Heavy concerns about the light axino explanation of the 3.5 keV X-ray line

Stefano Colucci, Herbi K. Dreiner, Florian Staub +1

An unidentified 3.5 keV line from X-ray observations of galaxy clusters has been reported recently. Although still under scrutiny, decaying dark matter could be responsible for thi…

On baryogenesis from dark matter annihilation

Nicolas Bernal, Stefano Colucci, Francois-Xavier Josse-Michaux +2

We study in detail the conditions to generate the baryon asymmetry of the universe from the annihilation of dark matter. This scenario requires a low energy mechanism for thermal b…
