Vacuum Homogeneous and Nonhomogeneous Metrics with Conventional and Quantized Metric Tensor: Singular or Nonsingular Solution
A. Tawfik, S. G. Elgendi, M. Hanafy
To investigate whether the Universe underwent a singularity or maintained a nonsingular state, we carry out analytical and numerical analyses of the evolution of the Raychaudhuri e…
Expansion Evolution of Nonhomogeneous Metric with Quantum-Mechanically Revisited Fundamental Metric Tensor
Abdel Nasser Tawfik, Azzah A. Alshehri, Antonio Pasqua
To explore the properties of space and initial singularities in the context of general relativity, where spacetime becomes poorly defined and no longer belongs to a regular manifol…
Derivation of Meson Masses in SU(3) and SU(4) Extended Linear-Sigma Model at Finite Temperature
Abdel Nasser Tawfik, Azar I. Ahmadov, Alexandra Friesen +3
The present study focuses on the mesonic potential contributions to the Lagrangian of the extended linear-sigma model (eLSM) for scalar and pseudoscalar meson fields across various…
Mass Spectrum of Non-Charmed and Charmed Meson States in Extended Linear-Sigma Model
Azar I. Ahmadov, Azza A. Alshehri, Abdel Nasser Tawfik
The mass spectrum of different meson particles is generated using an effective Lagrangian of the extended linear-sigma model (eLSM) for scalar and pseudoscalar meson fields and qua…
Reconstruction schemes of scalar field models for the Power Law Entropy Corrected Holographic Dark Energy model with Ricci scalar cut-off
Antonio Pasqua, Surajit Chattopadhyay, Irina Radinschi +2
In this work, we examine the cosmological characteristics of the Power Law Entropy Corrected Holographic Dark Energy (PLECHDE) model with infrared (IR) cut-off, which is determined…
Particle species and energy dependencies of freeze-out parameters in high-energy proton-proton collisions
Muhammad Waqas, Guang Xiong Peng, Fu-Hu Liu +4
We used blast wave model with Tsallis statistics to analyze the experimental data measured by ALICE Collaboration in proton-proton collisions at Large Hadron Collider and extracted…
Horizons: Nuclear Astrophysics in the 2020s and Beyond
H. Schatz, A. D. Becerril Reyes, A. Best +162
Nuclear Astrophysics is a field at the intersection of nuclear physics and astrophysics, which seeks to understand the nuclear engines of astronomical objects and the origin of the…
An appropriate statistical approach for nonequilibrium particle production
Abdel Nasser Tawfik, Eman R. Abou Elyazeed, A. A. Alshehri +1
The incapability of thermal models to accurately reproduce the horn-like structure of the Kaon-to-pion ratio measured at AGS, SPS, and low RHIC energies, as well as confirmed in th…
A Possible Solution of the Cosmological Constant Problem based on Minimal Length Uncertainty and GW170817 and PLANCK Observations
Abdel Magied Diab, Abdel Nasser Tawfik
We propose the generalized uncertainty principle (GUP) with an additional term of quadratic momentum motivated by string theory and black hole physics as a quantum mechanical frame…
Extensive/nonextensive statistics for distributions of various charged particles produced in p+p and A+A collisions in a wide range of energies
Abdel Nasser Tawfik, Hayam Yassin, Eman R. Abo Elyazeed
We present a systematic study for the statistical fits of the transverse momentum distributions of charged pions, Kaons and protons produced at energies ranging between 7.7 and 267…
Flow of anisometric particles in a quasi-2D hopper
Balazs Szabo, Zsolt Kovacs, Sandra Wegner +4
The stationary flow field in a quasi-two-dimensional hopper is investigated experimentally. The behavior of materials consisting of beads and elongated particles with different asp…
Silo outflow of soft frictionless spheres
Ahmed Ashour, Torsten Trittel, Tamas Börzsönyi +1
Outflow of granular materials from silos is a remarkably complex physical phenomenon that has been extensively studied with simple objects like monodisperse hard disks in two dimen…
