Neda Darvishi: "Extension of the Standard Model with a Doublet and a Complex Singlet and Heavy Vector Quarks"
Friday, 26 October 2018 from to (Europe/London)
I will discuss the extension of Standard Model by a doublet and a complex scalar singlet and a pair of heavy vector quarks. It will be shown that this model provides an extra source of spontaneous CP violation and a strong enough first order electroweak phase transition to suppress the baryon violating sphaleron process. This model contains a proper description of baryogenesis and also a suitable candidate for dark matter (DM) that provide a correct relic density of DM while fulfilling direct and indirect DM detection limits and simultaneously agreeing with the LHC results.
