A landscape for the cosmological constant and the Higgs mass
Parsa Ghorbani, Alessandro Strumia, Daniele Teresi
The cosmological constant and the Higgs mass seem unnaturally small and anthropically selected. We show that both can be efficiently scanned in Quantum Field Theories with a large…
Scalar gauge dynamics and Dark Matter
Dario Buttazzo, Luca Di Luzio, Parsa Ghorbani +5
We consider theories with one gauge group (SU, SO or Sp) and one scalar in a two-index representation. The renormalizable action often has accidental symmetries (such as global U(1…
A Simultaneous Study of Dark Matter and Phase Transition: Two-Scalar Scenario
Karim Ghorbani, Parsa Hossein Ghorbani
The simplest extension of the Standard Model by only one real singlet scalar can explain the observed dark matter relic density while giving simultaneously a strongly first-order e…
