Theoretical and Experimental Challenges in the Measurement of Neutrino Mass

Advances in High Energy Physics, Volume 2023, Issue 1, 2023., 2023
Neutrino masses are yet unknown. We discuss the present state of effective electron antineutrino mass from β decay experiments; effective Majorana neutrino mass from neutrinoless double‐beta decay experiments; neutrino mass squared differences from neutrino oscillation: solar, atmospheric, reactor, and accelerator‐based experiments; sum of neutrino ...

Decadal and Annual Variations in Meteoric Flux From Ulysses, Wind, and SOFIE Observations

Journal of Geophysical Research: Space Physics, Volume 127, Issue 10, October 2022., 2022
Abstract Our solar system is filled with meteoric particles, or cosmic dust, which is either interplanetary or interstellar in origin. Interstellar dust (ISD) enters the heliosphere due to the relative motion of the sun and the interstellar flow. Interplanetary dust (IPD) comes primarily from asteroid collisions or comet sublimation, and comprises the ...

Sounding Rocket Observation of Nitric Oxide in the Polar Night

Journal of Geophysical Research: Space Physics, Volume 127, Issue 6, June 2022., 2022
Abstract An altitude profile of Nitric Oxide (NO) in the 80–110 km altitude range was measured in the polar night from a sounding rocket on 27 January 2020. The observations were made using the technique of stellar occultation with a UV spectrograph observing the γ (1,0) band of NO near 215 nm.

A New Result for a Blow‐up of Solutions to a Logarithmic Flexible Structure with Second Sound

Advances in Mathematical Physics, Volume 2021, Issue 1, 2021., 2021
This paper is concerned with a problem of a logarithmic nonuniform flexible structure with time delay, where the heat flux is given by Cattaneo’s law. We show that the energy of any weak solution blows up infinite time if the initial energy is negative.

Global Existence and Decay Estimates of Energy of Solutions for a New Class of p‐Laplacian Heat Equations with Logarithmic Nonlinearity

Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021
The present research paper is related to the analytical studies of p‐Laplacian heat equations with respect to logarithmic nonlinearity in the source terms, where by using an efficient technique and according to some sufficient conditions, we get the global existence and decay estimates of solutions.

Existence, Nonexistence, and Stability of Solutions for a Delayed Plate Equation with the Logarithmic Source

Advances in Mathematical Physics, Volume 2021, Issue 1, 2021., 2021
In this work, we study a plate equation with time delay in the velocity, frictional damping, and logarithmic source term. Firstly, we obtain the local and global existence of solutions by the logarithmic Sobolev inequality and the Faedo‐Galerkin method. Moreover, we prove the stability and nonexistence results by the perturbed energy and potential well

Bouncing cosmology in modified gravity with higher-order curvature terms

Journal of High Energy Physics, 2023
A bouncing scenario of a flat homogeneous and isotropic universe is explored by using the reconstruction technique for the power-law parametrization of the Hubble parameter in a modified gravity theory with higher-order curvature and trace of the energy ...

Probing Scalar and Pseudoscalar Solutions to the g − 2 Anomaly

Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020
I investigate a class of models with scalar and pseudoscalar solutions to the g − 2 anomaly for both the muon and the electron over the mass range of perturbativity (mϕ≲50 GeV), with Yukawa couplings proportional to the lepton’s mass. In particular, I investigate the constraints from BaBar, beam dump experiments, Z decay measured quantities, LEP mono‐γ

Global Existence and Decay for a System of Two Singular Nonlinear Viscoelastic Equations with General Source and Localized Frictional Damping Terms

Journal of Function Spaces, Volume 2020, Issue 1, 2020., 2020
The current paper deals with the proof of a global solution of a viscoelasticity singular one‐dimensional system with localized frictional damping and general source terms, taking into consideration nonlocal boundary condition. Moreover, similar to that in Boulaaras’ recent studies by constructing a Lyapunov functional and use it together with the ...
