Chiral Phase Structure and In-Medium Modifications of Charmed Meson Masses within SU(4) extended Linear-Sigma Models
Nourhan M. Rfeek, Alexandra Friesen, Yuri Kalinovsky +4
We extend the Polyakov-loop-enhanced linear-sigma model to encompass four flavors and utilize it to analyze the light, strange, and charmed meson mass spectrum as it transitions fr…
Sneutrino Tribrid Inflation in Flipped : Confronting ACT DR6 and Planck Observations
Farishta Israr, Mansoor Ur Rehman, Saleh O. Allehabi
We construct a realization of sneutrino tribrid inflation within the -symmetric flipped grand unified theory. A vector-like pair of matter multiplets, $10_V+\overline{10…
Radiatively Corrected Hybrid Inflation: Parameter Scans and Machine Learning with ACT and Future CMB Experiments
Waqas Ahmed, Saleh O. Allehabi, Mansoor Ur Rehman
We investigate a realistic non-supersymmetric hybrid inflation model incorporating right-handed neutrinos and assess its viability in light of recent cosmological observations. At…
Temperature Dependence of the Masses of Various Meson States: A Comparative Study in SU(3) and SU(4) extended Linear-Sigma Model
Alexandra Friesen, Yu. Kalinovsky, Saleh O. Allehabi +3
In the extended Linear-Sigma Model (eLSM), the chiral phase structure of meson states, including pseudoscalars (), scalars (), vectors ($J^{pc}=1^{--}…
Revisiting Polynomial Hybrid Inflation: Planck and ACT Compatibility via Radiative Corrections
Waqas Ahmed, Saleh O. Allehabi, Mansoor Ur Rehman
We investigate the impact of one-loop radiative corrections in a non-supersymmetric model of hybrid inflation with a chaotic (polynomial-like) potential,, in…
Tribrid Inflation, Type II Leptogenesis, and Observable Gravitational Waves in
Waqas Ahmed, Saleh O. Allehabi, Farishta Israr +1
We present a concrete realization of tribrid inflation within the framework of the gauge group . In this model, inflation i…
High-accuracy optical clocks with sensitivity to the fine-structure constant variation based on Sm
Saleh O. Allehabi, V. A. Dzuba, V. V. Flambaum
We identify two metastable excited states in Sm highly charged ion as candidates for high accuracy optical clocks. Several atomic properties relevant to optical clock dev…
