Forecasting dark showers at Belle II

Journal of High Energy Physics, 2022
Dark showers from strongly interacting dark sectors that confine at the GeV scale can give rise to novel signatures at e + e − colliders. In this work, we study the sensitivity of B factory experiments to dark showers produced through an effective ...

Dark matter searches and energy accumulation and release in materials

SciPost Physics Proceedings, 2023
Efforts to identify dark matter by detecting nuclear recoils produced by dark matter particles reveal low-energy backgrounds of unknown origin in different types of detectors.

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Scalar dark matter behind b → sμμ anomaly

Journal of High Energy Physics, 2019
We construct a scalar dark matter model with U 1 L μ − L τ $$ \mathrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$ symmetry in which the dark matter interacts with the quark flavours, allowing lepton non-universal b → s ℓ ℓ ¯ $$ s\ell \overline{\ell} $$ decays. The

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Addressing the Crisis in Fundamental Physics

, 2007
I present the case for fundamental physics experiments in space playing an important role in addressing the current "dark energy'' crisis. If cosmological observations continue to favor a value of the dark energy equation of state parameter w=-1, with no

Fingerprinting Dark Energy III: distinctive marks of viscosity [PDF]

, 2012
The characterisation of dark energy is one of the primary goals in cosmology especially now that many new experiments are being planned with the aim of reaching a high sensitivity on cosmological parameters.

Spectroscopic Needs for Imaging Dark Energy Experiments: Photometric Redshift Training and Calibration

, 2013
Large sets of objects with spectroscopic redshift measurements will be needed for imaging dark energy experiments to achieve their full potential, serving two goals:_training_, i.e., the use of objects with known redshift to develop and optimize photometric redshift algorithms; and_calibration_, i.e., the characterization of moments of redshift (or ...

New constraints on coupled dark energy from the Planck satellite experiment [PDF]

Physical Review D, 2013
We present new constraints on coupled dark energy from the recent measurements of the cosmic microwave background anisotropies from the Planck satellite mission. We found that a coupled dark energy model is fully compatible with the Planck measurements, deriving a weak bound on the dark matter-dark energy coupling parameter xi = -0.49(-0.31)(+0.19) at ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
