Observation of the rare $B_{s}^{0} \to μ^{+} μ^{-}$ decay from the combined analysis of CMS and LHCb data

The CMS, LHCb Collaborations, : +2807

A joint measurement is presented of the branching fractions $B_{s}^{0} \to μ^{+} μ^{-}$ and $B^{0} \to μ^{+} μ^{-}$ in proton-proton collisions at the LHC by the CMS and LHCb experiments. The data sam…

Reconstruction of $f (T)$ -gravity in the absence of matter

W. El Hanafy, G. L. Nashed

We derive an exact $f (T)$ gravity in the absence of ordinary matter in Friedmann-Robertson-Walker (FRW) universe, where $T$ is the teleparallel torsion scalar. We show that vanishi…

Double Higgs peak in the minimal SUSY B-L model

W. Abdallah, S. Khalil, S. Moretti

Motivated by a $\sim 3 σ$ excess recorded by the CMS experiment at the LHC around a mass of order $\sim 137$ GeV in $Z Z \to 4 l$ and $γ γ$ samples, we analyse the discovery potential o…

The Hidden Flat Like Universe: Starobinsky-like inflation induced by f(T) gravity

W. El Hanafy, G. G. L. Nashed

We study a single fluid component in a flat like universe (FLU) governed by $f (T)$ gravity theories, where $T$ is the teleparallel torsion scalar. The FLU model, regardless the val…

Neutrino Mixing and Leptogenesis in $μ - τ$ Symmetry

E. I. Lashin, N. Chamoun, C. Hamzaoui +1

We study the consequences of the $Z_{2}$ -symmetry behind the $μ$ -- $τ$ universality in neutrino mass matrix. We then implement this symmetry in the type-I seesaw mechanism and show ho…

A Comparative Study of Meta-heuristic Algorithms for Solving Quadratic Assignment Problem

Gamal Abd El-Nasser A. Said, Abeer M. Mahmoud, El-Sayed M. El-Horbaty

Quadratic Assignment Problem (QAP) is an NP-hard combinatorial optimization problem, therefore, solving the QAP requires applying one or more of the meta-heuristic algorithms. This…

Fermion masses and mixing in $Δ (27)$ flavour model

Mohammed Abbas, Shaaban Khalil

An extension of the Standard Model (SM) based on the non-Abelian discrete group $Δ (27)$ is considered. The $Δ (27)$ flavour symmetry is spontaneously broken only by gauge singlet sc…

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…

Regularization of $f (T)$ gravity theories and local Lorentz transformation

G. G. L. Nashed

We regularized the field equations of $f (T)$ gravity theories such that the effect of Local Lorentz Transformation (LLT), in the case of spherical symmetry, is removed. A "general…

A Built-in Inflation in the $f (T)$ -Cosmology

G. G. L. Nashed, W. El Hanafy

In the present work we derive an exact solution of an isotropic and homogeneous Universe governed by $f (T)$ gravity. We show how the torsion contribution to the FRW cosmology can p…
