BSM Cosmology from BSM Physics

, 2021
International audienceNow Standard $\Lambda$CDM cosmology is based on physics Beyond the Standard Model (BSM), which in turn needs cosmological probes for its study.

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

Dynamical evolution of gravitational leptogenesis [PDF]

Journal of High Energy Physics, 2020
Radiatively-induced gravitational leptogenesis is a potential mechanism to ex- plain the observed matter-antimatter asymmetry of the universe. Gravitational tidal effects at the quantum loop level modify the dynamics of the leptons in curved spacetime ...

Cosmological constraints on dark scalar

Journal of High Energy Physics, 2022
We discuss cosmological constraints on a dark scalar particle mixing with the Standard Model Higgs boson. We pay particular attention to the dark scalar production process when the reheating temperature of the Universe is very low, which allows us to ...

Multifield positivity bounds for inflation

Journal of High Energy Physics, 2023
Positivity bounds represent nontrivial limitations on effective field theories (EFTs) if those EFTs are to be completed into a Lorentz-invariant, causal, local, and unitary framework.
