Collider probes of baryogenesis with maximal CP asymmetry

Journal of High Energy Physics
We propose a novel collider probe of baryogenesis at TeV scale by measuring decay asymmetries into particle and anti-particle final states. Motivated by the idea of Dirac leptogenesis, we consider an extension of the standard model with new colored and ...

Low radioactive material screening and background control for the PandaX-4T experiment

Journal of High Energy Physics, 2022
PandaX-4T is a ton-scale dark matter direct detection experiment using a dual-phase TPC technique at the China Jinping Underground Laboratory. Various ultra-low background technologies have been developed and applied to material screening for PandaX-4T ...

Modeling the Redistribution of Dust Across the Martian Surface for Mars Years 24 to 36

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Global Dust Events (GDEs) transport huge amounts of dust across the Martian atmosphere. GDEs occur only every few Mars Years (MYs), but the reasons behind this inter‐annual variability remain poorly understood. The question whether surface dust exhaustion and subsequent replenishment explain this variability remains open.

On the Lambda-evolution of galaxy clusters

European Physical Journal C: Particles and Fields, 2020
The evolution of galaxy clusters can be affected by the repulsion described by the cosmological constant. This conclusion is reached within the modified weak-field General Relativity approach where the cosmological constant $$\varLambda $$ Λ enables to ...

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$

Sensitivity analysis of gamma spectroscopy system with dual high-purity germanium detectors

He jishu, 2022
BackgroundIn rare decay experiments, for instance dark matter and neutrino experiments, rays produced by the radioavtive decay in detector material induce extra experiment background, the energy deposition would contaminate the concerned region ...

Mesoscale Modeling of Titan’s Shangri‐La Region: The Impact of Surface Properties on Winds

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The knowledge of Titan’s near‐surface atmosphere is sparse. The Huygens descent probe measured winds, and the multiple dune field observations and possible dust storms suggest active near‐surface dynamics. The Dragonfly rotorcraft lander will fly close to the surface in the Shangri‐La region, near the Huygens landing site, where complex dune ...
