Discreteness of time in the evolution of the universe
Mir Faizal, Ahmed Farag Ali, Saurya Das
In this paper, we will first derive the Wheeler-DeWitt equation for the generalized geometry which occurs in M-theory. Then we will observe that M2-branes act as probes for this ge…
Remnant for all Black Objects due to Gravity's Rainbow
Ahmed Farag Ali, Mir Faizal, Mohammed M. Khalil
We argue that a remnant is formed for all black objects in gravity's rainbow. This will be based on the observation that a remnant depends critically on the structure of the rainbo…
Absence of Black Holes at LHC due to Gravity's Rainbow
Ahmed Farag Ali, Mir Faizal, Mohammed M. Khalil
In this paper, we investigate the effect of Planckian deformation of quantum gravity on the production of black holes at colliders using the framework of gravity's rainbow. We demo…
Remnants of Black Rings from Gravity's Rainbow
Ahmed Farag Ali, Mir Faizal, Mohammed M. Khalil
In this paper, we investigate a spinning black ring and a charged black ring in the context of gravity's rainbow. By incorporating rainbow functions proposed by Amelino-Camelia, et…
Double Higgs peak in the minimal SUSY B-L model
W. Abdallah, S. Khalil, S. Moretti
Motivated by a excess recorded by the CMS experiment at the LHC around a mass of order GeV in and samples, we analyse the discovery potential o…
A Proposal for Testing Gravity's Rainbow
Ahmed Farag Ali, Mohammed M. Khalil
Various approaches to quantum gravity such as string theory, loop quantum gravity and Horava-Lifshitz gravity predict modifications of the energy-momentum dispersion relation. Magu…
Neutrino Mixing and Leptogenesis in Symmetry
E. I. Lashin, N. Chamoun, C. Hamzaoui +1
We study the consequences of the -symmetry behind the -- universality in neutrino mass matrix. We then implement this symmetry in the type-I seesaw mechanism and show ho…
Fermion masses and mixing in flavour model
Mohammed Abbas, Shaaban Khalil
An extension of the Standard Model (SM) based on the non-Abelian discrete group is considered. The flavour symmetry is spontaneously broken only by gauge singlet sc…
Absence of an Effective Horizon for Black Holes in Gravity's Rainbow
Ahmed Farag Ali, Mir Faizal, Barun Majumder
We argue that the divergence in time for the asymptotic observer occurs because of specifying the position of the Horizon beyond the Planck scale. In fact, a similar divergence in…
Electron EDM as a Sensitive Probe of PeV Scale Physics
Tarek Ibrahim, Ahmad Itani, Pran Nath
We give a quantitative analysis of the electric dipole moments as a probe of high scale physics. We focus on the electric dipole moment of the electron since the limit on it is the…
Heavy neutrinos and neutral gauge boson Z' at the LHC
A. A. Abdelalim, A. Hammad, S. Khalil
We explore possible signatures for heavy neutrinos and neutral gauge boson, Z', in TeV scale B-L extension of the Standard Model (BLSM) with inverse seesaw mechanisms at the Large…
AdS/CFT Correspondence Beyond its Supergravity Approximation
Mir Faizal, Ahmed Farag Ali, Ali Nassar
We will study the AdS/CFT correspondence in an intermediate region between the strong form of this correspondence (string theory on AdS being dual to a boundary CFT), and the weak…
Minimal Length, Friedmann Equations and Maximum Density
Adel Awad, Ahmed Farag Ali
Inspired by Jacobson's thermodynamic approach[gr-qc/9504004], Cai et al [hep-th/0501055,hep-th/0609128] have shown the emergence of Friedmann equations from the first law of thermo…
Cosmology from quantum potential
Ahmed Farag Ali, Saurya Das
It was shown recently that replacing classical geodesics with quantal (Bohmian) trajectories gives rise to a quantum corrected Raychaudhuri equation (QRE). In this article we deriv…
Planck-Scale Corrections to Friedmann Equation
Adel Awad, Ahmed Farag Ali
Recently, Verlinde proposed that gravity is an emergent phenomenon which originates from an entropic force. In this work, we extend Verlinde's proposal to accommodate generalized u…
Fractional quantum Hall states as an Abelian group
Ali Nassar
We show that the set of double-layer Fractional Quantum Hall (FQH) states with a given topological order form a finite Abelian group under a new product. This group structure makes…
Black Hole Remnant from Gravity's Rainbow
Ahmed Farag Ali
In this work, we investigate black hole (BH) physics in the context of gravity rainbow. We investigate this through rainbow functions that have been proposed by Amelino-Camelia, et…
Towards a Cosmology with Minimal Length and Maximal Energy
Ahmed Farag Ali, Barun Majumder
The Friedmann-Robertson-Walker (FRW) universe and Bianchi I,II universes are investigated in the framework of the generalized uncertainty principle (GUP) with a linear and a quadra…
SU(5) Octet Scalar at the LHC
S. Khalil, S. Salem, M. Allam
Color scalars are salient features of non-minimal SU(5) model, where Higgs sector is extended by 45-dimensional multiplet. We show that gauge coupling unification can be realized i…
