Fermionic Dark Matter and New Scalar Production in $e^{+} e^{-} \to H^{+} H^{-}$ at Colliders

Asmaa AlMellah, Faeq Abed, Gaber Faisel

We investigate the pair production process $e^{+} e^{-} \to H^{+} H^{-}$ in the framework of the scotogenic model. The production mechanism receives contributions at tree level from photon a…

Dark Higgs in Hidden Sector as a Probe for Dark Matter

Faeq Abed, Asmaa AlMellah, Gaber Faisel

This study presents a sensitivity analysis of exotic Higgs boson decays at the electron--positron stage of the Future Circular Collider (FCC-ee), performed within the FCCAnalyses f…

Flavor Violations in $B$ -Mesons within Non-Minimal SU(5)

Bhubanjyoti Bhattacharya, Alakabha Datta, Gaber Faisel +2

Recent anomalies in $B$ -meson decays, such as deviations in $R_{D^{(*)}}$ and $B \to K ν ν ˉ$ , suggest possible lepton flavor universality violation and new exotic interactions. I…

CP Asymmetry in $τ \to K π ν_{τ}$ within Non-Minimal $S U (5)$

Gaber Faisel, S. Khalil

Direct CP asymmetry in semi-leptonic $τ$ decays is an intriguing hint for new physics beyond the standard model. We investigate the CP asymmetry in $τ^{-} \to K_{S}^{0} π^{-} ν_{τ}$ and $τ^-…

Thermodynamic and cosmological parameters of early stages of the Universe

Amr Abd Al-Rahman Youssef, Gaber Faisel, Hakan Akyildirim

The early Universe was characterized by the presence of heavy particles that decoupled at different temperatures leading to different phases of the Universe. This had a consequence…

Investigating $R_{D}$ and $R_{D^{*}}$ anomalies in a Left-Right model with an Inverse Seesaw

K. Ezzat, G. Faisel, S. Khalil

We investigate $R_{D}$ and $R_{D^{*}}$ anomalies in a low scale left-right symmetric model based on $S U (3)_{C} \times S U (2)_{L} \times S U (2)_{R} \times U (1)_{B - L}$ with a simplified Higgs secto…
