Quantum Zeno Dynamics of Two Interacting Particles
Varqa Abyaneh, Parsa Ghorbani
According to quantum Zeno dynamics (QZD), the evolution of a quantum system can be restricted to a subspace of its Hilbert space by frequent measurements. A crucial question in QZD…
Fermion Dark Matter Effect on Electroweak Phase Transition
Soudeh Mirzaie, Karim Ghorbani, Parsa Ghorbani
The addition of extra scalars to the Standard Model (SM) of particle physics enriches the vacuum structure and consequently gives rise to strong first-order phase transitions (EWPT…
Loop quantum effects on direct detection prediction in two-scalar dark matter scenario
Karim Ghorbani, Parsa Ghorbani
We investigate the effect of quantum corrections on the elastic scattering cross section of dark matter off nucleus in two-scalar dark matter model. Among two extra singlet scalars…
Gravitational waves from thermal heavy scalar dark matter
Parsa Ghorbani
We propose a gauge singlet scalar with mass around 1-100 TeV as a thermal heavy dark matter candidate along with a dilaton as a Higgs portal mediator in a dimensionless scalar exte…
Two pseudo-Goldstone bosons in the Gildener-Weinberg model
Parsa Ghorbani
In a dimensionless multi-scalar extension of the Standard Model, Gildener and Weinberg assumed that along a flat direction, there is only one classically massless scalar, known as…
