Investigating three body charm hadron decays with missing energy within non-minimal SU(5) Open
In the Standard Model, the $$c \rightarrow u\nu {\bar{\nu }}$$ transition arises only at the one-loop level, leading to extremely suppressed branching ratios for the corresponding three-body decays of charmed hadrons. This suppr…

Flavor Violations in $B$-Mesons within Non-Minimal SU(5) Open
Recent anomalies in $B$-meson decays, such as deviations in $R_{D^{(*)}}$ and $B\to Kν{\barν}$, suggest possible lepton flavor universality violation and new exotic interactions. In this work, we explore these anomalies within a non-minima…

CP Asymmetry in $τ\to Kπν_τ $ within Non-Minimal $SU(5)$ Open
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 $τ^- \to K^- π^0 ν_τ$ decays in non-minimal SU(5) model, with 4…

Phenomenology of the hidden SU(2) vector dark matter model Open
We investigate the phenomenology of an extension of the Standard Model (SM) by a non-abelian gauge group $SU(2)_{HS}$ where all SM particles are singlets under this gauge group, and a new scalar representation $ϕ$ that is singlet under SM …

Analytic solutions for the energy density and the temperature of the QGP in the early Universe Open
After the Big Bang and at a time estimated to be a millionth of a second, the Universe was in a phase that filledwith quark-gluon plasma. Due to the high temperature, the strong coupling constant that describes the strength of the strong f…

Supersymmetric NJL-Type Model for a Real Superfield Composite Open
The Nambu–Jona-Lasinio (NJL) model is a classic theory for the strong dynamics of composite fields and symmetry breaking. Supersymmetric versions of the NJL-type models are certainly of interest too. Particularly, the case with a composite…
