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…
