Gravitational Waves from Nnaturalness

Journal of High Energy Physics
We study the prospects for probing the Nnaturalness solution to the electroweak hierarchy problem with future gravitational wave observatories. Nnaturalness, in its simplest incarnation, predicts N copies of the Standard Model with varying Higgs mass ...

Signal identification with Kalman Filter towards background-free neutrinoless double beta decay searches in gaseous detectors

Journal of High Energy Physics, 2021
Particle tracks and differential energy loss measured in high pressure gaseous detectors can be exploited for event identification in neutrinoless double beta decay (0νββ) searches.

Noise Reduction Method for Radio Astronomy Single Station Observation Based on Wavelet Transform and Mathematical Morphology [PDF]

Research in Astronomy and Astrophysics
The 21 cm radiation of neutral hydrogen provides crucial information for studying the early universe and its evolution. To advance this research, countries have made significant investments in constructing large low-frequency radio telescope arrays, such

Colorful particle production at high-energy muon colliders

Journal of High Energy Physics
A high-energy μ + μ − collider provides a wide variety of mechanisms for the production of new heavy particles. While the reach for such particles via the direct annihilation of μ + μ − will approach the center-of-mass energy of the collider, the ...

Hybrid Streaming Workflows for Scalable Visualization in Astronomy and Cosmology

SN Computer Science
Modern astrophysics and cosmology generate petabyte-scale datasets that demand advanced tools for scalable visualization and analysis. The Visualization Interface for the Virtual Observatory (VisIVO) provides multi-dimensional data exploration, but its ...

Dynamics of dark matter misalignment through the Higgs portal

Journal of High Energy Physics
A light singlet scalar field feebly coupled through the super-renormalizable Higgs portal provides a minimal and well-motivated realization of ultra-light bosonic dark matter.

A global analysis of charmless two body hadronic decays for anti-triplet charmed baryons

Journal of High Energy Physics, 2022
Recently Belle collaboration reported new measurements for the branching fractions with the first observing two processes of B Ξ c 0 → Λ K S 0 $$ \mathcal{B}\left({\Xi}_c^0\to \Lambda {K}_S^0\right) $$ , B Ξ c 0 → Σ 0 K S 0 $$ \mathcal{B}\left({\Xi}_c^0 ...

Lectures on Astronomy, Astrophysics, and Cosmology

, 2007
This is a written version of a series of lectures aimed at undergraduate students in astrophysics/particle theory/particle experiment. We summarize the important progress made in recent years towards understanding high energy astrophysical processes and we survey the state of the art regarding the concordance model of cosmology.

Light quark decays of doubly heavy baryons in light front approach

European Physical Journal C: Particles and Fields, 2023
We explore the semileptonic and nonleptonic decays of doubly heavy baryons $$(\Omega _{cc}^{(*)+},\Omega _{bb}^{(*)0},\Omega _{bc}^{(*)-},\Omega _{bc}^{\prime 0})$$ ( Ω cc ( ∗ ) + , Ω bb ( ∗ ) 0 , Ω bc ( ∗ ) - , Ω bc ′ 0 ) induced by the $$s\rightarrow u$
